Mechanical Questions Thread

I would like to understand how the Bubbling prefix on flasks works.

My pathfinder uses the following tree:

(summary: 50% increased effect of flasks, 28% flask effect duration, 30% increased life recovery from flasks)

On this character, Bubbling is an instant heal (or the duration is a frame or less and hence undetectable for me).

Also, it appears that neither flask life recovery rate nor flask effect duration modifiers modify it, as observed by toggling


In both cases, I recover 3888 hp (tested with vaal pact). I am confused two-fold here:

1) Why didn't the belt increase my recovery? I expected the game to first calculate the amount of heal-per-second and total duration, and then apply the instant/non-instant split. Or well, let me rephrase: I wish it was this way, so that my Belt would be useful! :)

2) Why would the Bubbling Flask be (near) instant?

Additionally I would appreciate a derivation of the exact recovery amount.

Edit: Forgot to link the flask in question:

So ive been playing for a few years now and in the past when socketing and fusing it has always stoped at max. ive noticed recently that when socketing it still stops at 4 or 6. but now when fusing it rolls past the max; atleast with 4. Is this some kind of new rolling thing or what cuz i wasted alot of fusings due to this. Ive never had this issue just only recently in the past 2 weeks or so. any ideas would be awesome.

This has, in practical terms, always been the case. It was for maybe half a day true that four-links could not be rerolled.
A quick question about the interaction of slowing effects:

In patch 2.1.0c this statement is listed: "A cap of 75% now applies to the action speed reduction caused by Temporal Chains..."

First -- I assume it does but I ask for completeness -- does this 75% apply to all slowing effects?

Second, of the slowing effects that stack:

Chill: 30% slow
Hinder: 25% slow (Arbitrary; realistic number)
Temporal Chains: 29% slow (Level 20/0% quality)

Are these effects ADDITIVE or MULTIPLICATIVE?

In other words does the above example result in enemies being slowed by:
30%+25%+29%=84% --> capped at 75% slow?
OR
1-(1-30%)*(1-25%)*(1-29%)=62.7% slow?
Thanks in advance!
If I ignite with explosive arrow, besides the more damage on hit; Does Less Duration affect the burning damage ie Does it double dip?

I have read a few days ago, on a forum post, that Temporal Chains is not stacking with other Slowing effects (not sure about movement like Hinder) but they said Chill doesn't stack with it anymore, so the maximum slow you can possibly reach is:

4L 20%TChains21+Empower4+Enhance5+20%Blasphemy+DyingBreath+AnimatedDyingBreath = 75.40% Slow

And I believe that they are Additive, since my cheaply builded Arctic Breath + TempChains summoner from 2 years ago used to make bosses attack/cast ridiculously slow.


I can be wrong on both statements tho, so I would really like a 2nd opinion on this, specially because I'm building a curse based Summoner on hardcore again and I've been searching everywhere for this info.

I hope I have helped.

When you cast a single firestorm and deal 3 hits to the monsters A and B...
-If you crit, you crit A & B (no assassin's mark).

This is both backwards and incomplete.
If you critically strike either A or B, then you count as having crit with the skill (not the other way around). The crit roll being the same for the whole skill means that if your chance to crit against both A and B is the same, you'll crit both or niether, but Assassin's Mark is not the only thing that could cause such a difference. Any conditional or enemy-specific crit chance modifier could do this.

If A is cursed with Assassin's mark, one possible outcome is that A recives a crit and B doesn't.
Yes. In this case, you still count as having crit with the skill.

If you crit, you support firestorm with power charge on crit level 1, you have 35% chance to get a power charge.
If you crit, you support firestorm with power charge on crit level 1, you have 92.4% chance to get a power charge (because the chance to roll for a power charge is different in each hit. But with a maximum of 1 because PCOC is limited to 1 charge per cast).
Each critical strike you get has a 35% chance to generate a power charge, but you can't gain more than one. In theory this should be a 35% chance to gain a charge if you get a crit (i.e. if you get at least one critical strike on A or B), but if you fail that roll, the skill doesn't know it tried, so will re-roll on each subsequent hit - the knowledge that you've already tried to gain a power charge for the crit is only possible if you have the charge. So it will currently keep rolling on each hit.

As above.

-If you don't crit, you support firestorm with elemental proliferation (0% quality), and you have 15% chance to ignite, A receives 3 hits, B receives 3 hits, you have 62.3% chance to ignite the pack (because the chance to roll for ignite is different in each hit).
Each hit has a 15% chance to ignite the monster being hit. That ignite will be based on that hit, and will proliferate to other enemies within a small radius. It's highly unlikely that one ignite will hit an entire pack unless you've gone to effort to compact them in, and even if it can, elemental proliferation is still not useless, as every hit proliferates, and since the strongest ignite applies, more individual hits igniting means some will roll more fire damage, and thus a stronger ignite, than others. Igniting each monster individually without proliferation is less good than igniting each monster idividually with proliferation, because if one of them rolls high, all of the enemies wi proliferation range take that higher damage.

-If you crit, and you have a surgeon flask, A receives 3 hits, B receives 3 hits, you have 73.8% chance to get a flask charge (the chance to get a flask charge is calculated on each of the 6 hits, but you get a max of 1 charge).
-If you crit, and you have a surgeon flask, A receives 3 hits, B receives 3 hits, you have a 20% chance to get a flask charge for every hit (a minimum of 0 and a max of 6).
Each hit has it's own chance, but you'll only be able to get one, just like the charges.

Is the Romira's Banquet and Herald of Thunder incompatibility intended? (because it is, right? was hard to test, I tested without increased critical strikes supports too).
They are not incompatable. However, Herald of Thunder has the same restriction as any normal skill that it can only gain one charge per skill use, so once you've got that one charge, you'd need to refresh the Herald to get another. This is likely to be changed in a future patch.
"
Visca wrote:
When Herald of Thunder + increased critical strikes crits, does it crit for all the bolts it launches on his duration (6.0 seconds)?
Each bolt has it's own crit roll. They are independant.

Visca wrote:
Killing a shocked enemy while herald of thunder is active, augments the time it is active, start a "new" herald of thunder's "rain" (see previous question) or works as other status ailments (active the most powerful but when it expires the weak keeps working).
When you kill a shocked enemy, it creates a set of lightning bolts. This is not an effect on you or a status ailment. Each set of bolts is independant (and has it's own location).

Visca wrote:
Herald of Thunder + Increased Critical Strikes + Power charge on crit: How often will it roll for a power charge? every time a bolt falls? only once for the entire duration of the herald of thunder duration (and to be able to get another charge only when there is a moment without herald of thunder active)? Or basically just any of the prior iterations
Just like the above charge-gainging cases, it will roll on eahc time the event occurs, until you get the charge.

If traps can hit, why curse on hit won't work with them?
Because the skill you used that was linked to Curse on Hit and a Curse threw a trap but never hit anything, and the skill the trap was the trap's only skill, and had no curses to apply. Traps do not have sockets. when you trappify a skill, you're changing that skill to create a trap that will have only that skill, and none of your other ones.

I've seen multiple people reporting that Blast Rain can't miss. Is that the case? If so is this a bug or working as intended (due to the explosions being secondary damage or something?).
As mentioned previously in the thread, Blast Rain was bugged and incorrectly checking spell dodge rather than regular evasion+dodge.
"
AlsoD wrote:
How does that affect crit confirmation rolls?
Not at all. The bug only applied to the initial hit check.

AlsoD wrote:
How does the "attacks can't miss" mod affect crit confirmation rolls?
There is no "attacks can't miss" mod. There's a "hits can't be evaded" mod, and it means evasion does nothing against those hits, including when confirming the crit.

What is the base (average) range of a ethereal knives projectile (with no increased/reduced projectile speed)?
The projectiles move at an average speed of close to 120 units/s for roughly 0.25 seconds of travel before they stop colliding with things, putting their effective range at somewhere around 30ish units. Then inherently have a variation of +/-40% base speed, but the average will be around 30.

What is the base (average) range of a freezing pulse projectile?
Similar calculation of around 165ish speed and 0.375s travel time suggests 60ish units.

Is there any rule of thumb what's the actual range of 'nearby enemies'?
No. "Nearby" is specifically (and only) meant to indicate that there is a range on an effect, not anything about what that range is.

25 units.

There's a valid concern here, but I'm fine filtering out such "noise" manually, and not including it in my responses (with this exception, because this is worth discussing). I've updated the OP to include a link to the thread filtered to just my posts, so people can just get answers (with their associated questions) that way.
There may be more on the way to help people sort through and find the answers they're interested in, but I can't say anything for sure yet.

Character (using Voll's Protector, Commandment of Frost enchantment on gloves) perform default attack on undamaged low level mob, rolls crit, do damage equal or higher than 90% mob's life pool (crit strikes have culling strike), kills the mob, triggers 'on kill' enchantment and getting 2 power charges.

Where is 2nd power charge comes from?
Definitely it's Commandment of Frost crit (there were no other mobs around)

Does it mean 'dead' mobs leave targetable 'body' for some time after death, before 'body hit the floor'?
Not for any time, no, but Commandment Of Frost happens during the killing hit - as an on-kill triggered effect, it is part of the process of the monster dying, so the monster hasn't finished dying when the enchantment skill hits it again.
This is on the list to improve long-term, but since it's rare and doesn't cause any real problems, is fairly low priority.

How does Commandment of Winter work?

Is it the same mechanic as Ball Lightning?
No. Ball Lightning does no pulse, it sends bolts of lightning at specific targets independantly. The "of Winter" skills have a projectile that periodically deals area damage around it as it travels. This is the same mechanic as the pulsing projectiles used by the "Maelstom" monsters.

We are currently changing descriptions to better distinguish between granting "immunity to X" and "cannot be affected by X" (shortened to "cannot be Xed" where applicable). Once this change is finished and made live (currently planned as part of 2.4.0, but that could change), gaining immunity to something will remove instances of that thing, in addition to preventing new instances, while "cannot be affected by" will prevent new effects applying, but not remove existing ones.

This can be worked out from the above info for a "perfect" case if you want, but in practice will vary because things have to be placed at an integer position, so angles change how far exactly things actually move (And thus how long they're moving for, since speed is constant).

Entities that are too far from any player are "asleep" and take no actions. Entities that are outside this sleep range of your player specifically, do not exist on your client (but may still be awake if in range of a different player. The exception to this is other players, who are always awake. If another player fires a projectile while outside your sleep range, it may not be able to create the projectile on your client.
This is unlikely to cause any actual mechanical effect, due to projectiles being unable to travel as far as the sleep range.

Intuitive leap

I'm not sure if you didn't saw the questions because you only posted the answers when you got the whole page (taking several days), but i edited on my post some questions that weren't answered. Please don't take this as "insisting". It's just in case you overlooked them:

"
-While having Ancestral Bond Rigteous fire does damage to you and don't damage enemies, while the wording is EXACTLY the same but changing "Enemies" for "You". If it's not you who damage yourself, then neither it's you who damage the enemies, or if it's you then you can't damage anybody (because Ancestral Bond) and that includes you (of course the objective was to gain a 40% more spell damage buff).
-I'm not sure about this question (because somebody asked me to edit it here because he didn't want to wait until you get to page 70), but why doesn't work the combo: CWDT (level 2) + Molten Shell (level 11) on a +2 fire weapon. You can equip that Molten Shell on level 40, so the level requirement for that specific gem on that specific setup is level 40, regardless of it's gem level. Is it intended or a bug?


I learned a lot. Herald of thunder can't sustain pcoc for now, and a multi-hit skill like firestorm/ice storm/bladefall are good choices to replenish surgeon flask's.

Could someone tell me can skills/effects from glove enchantments crit? if so affected by global crit/spell crit? ty
