Is the burn damage from this cold based or fire based? Say I hit a mob for 100 cold damage and it burns - what happens if I use frostbite? flammability?

Why southbound?
1. It gives a load of cold res and HP for very low price (mentioned already)
2. While using Poison on Traps, Totems or Minions the "On Killing a Poisoned enemy" Bino's effect only works if the Poison kill the enemy.
Therefore, we face a huge problem: most of mobs are killed with Bladefall's first impact, not Poison => Bino's affix doesn't work and we don't get our poison spreading (which greatly slows down our clearspeed).
However, Southbound unique affix "Your Hits can only Kill Frozen enemies" fits this case perfectly. It does apply to Bladefall initial damage, but don't apply to Poison DoT. Therefore, Bladefall will lower HP of mobs to 1, but won't kill them. Then Poison applies and finish mob instantly, and Bino's spread the poison. Works like a charm!
(open-post doesn't mention this mechanic, and it can confuse a lot of beginners (like it did with me :D )


so i would say, you get the kill if, by any chance, you kill the mob with the poison effect.

(can't say anything about the second part of ur message.. hope i could help a bit)


This answers why I get the corrupting stacks I suppose but then again I'd say it still only adds to the confusion. Either the totem/trap/mine skills should be counted as their own entities consistently or they shouldn't at all and the distinction between you and your totems is unnecessary. Now it's in between where some parts counts as you and others don't.

Hi Mark, I am aware that reducing duration of dots (poison, bleed) does not strictly increase damage as its per second.

On that note though, suppose poison was reduced to 0.69 seconds, would it just do 69% of a tick damage?
Does the first stage of Flameblast deal 100% tooltip damage, then each additional stage deals 110% more? This would result in a 10 stack Flameblast dealing 9*110% = 990% more damage, or 10.9x your tooltip.

I have seen almost all sources say it deals 12x tooltip, but my own tests of the damage at stage 1 matches the tooltip so that would require an 11 stack Flameblast. It could be useful to correct community misconceptions if it does indeed only deal up to 10.9x base/tooltip damage.

A question about Wild Strike, how are the secondary effects calculated? Do they do damage based on the weapon damage and type, or based on their chosen element? And what are the ratios on the chosen effects? And how exactly does it interact with support gems, using Elemental Focus, with a full lightning build, I cant seem to shock or freeze, but mobs still get ignited every once in a while. And how exactly is the tooltip calculated, is it just based on the initial hit, or does it take in to account the secondary procs?

Hi mark, thanks for doing this!

I've been playing with hiltless the new 2h reaver sword, and I was wondering if fortify is reducing the reflected damage it does to me.

After reading that the reflected damage is not a hit, and then reading the poe wiki for fortify which says it reduces the damage of hits, I am unsure if it actually is reducing the damage or not.

Thanks.

The support team linked me to this thread,
so i have an issue with pierce chance from the Drillneck quiver. it is supposed to give "10% chance of Arrows piercing" but it doesnt increase the chance to pierce, that is indicated by the tooltip of my Lightning Arrow
Skill Tooltips intentionally only show the stats that are specific to that skill. They don't show global things that affect all skills.
If you want to see everything a skill does, including all your global stats, the character panel, not the skill popup, is the place to do that.

Consecrated ground created by "Decree of Light" gloves enchant (example below) seems to grant much higher health regen than expected.

Tested with a character with around 7.5k life, their life regen spikes by ~900 while standing on it, close to 12% of their maximum life.
Decree of Light skill description reads "4% of maximum life regenerated per second" and consecrated ground created by a Sulphur flask grants the expected 4% life regen. Where is this difference coming from?
A bug. Thanks for bringing it to my attention.

Related to above, do you still benefit from "when you take a critical strike" effects if you block said critical strike? For example, Avenger's prefix on flasks.
Yes.
"
Whirling Blades doesn't seem to be interruptible.
It's just as interruptable as any other skill.
"
what happens if I receive damage from a hit large enough to normally stun me while whirling?
You get stunned. Currently, there's a bug where the movement continues, meaning you slide while playing the stun animation, but you're no longer damaging things. The bug will be fixed in a future patch.
"
Is there a maximum range I need to be within of monsters killed (by me) to gain experience?
Yes. Experience for a kill is assigned to players within range, regardless of whether any of those players are the ones which killed it.
"
For example, do monsters dying to degen when I'm already several screens away still grant experience no matter what?
If you're actually getting "several screens away" before they die, they probably aren't dying at all, since time stops passing for things outside the player's wake range.
"
Do strongbox prefixes have any effect on quantity of items contained
No.
"
or would opening a normal strongbox be the same as opening a magic one (with no suffixes) loot wise?
Also no. Magic strongboxes inherently have increased quantity/rarity of items for being magic, but this is unrelated to any prefices they have. Similarly for rares and uniques.

The passive is clearly written as "20% more evasion chance when not on full Energy Shield", which you knew already.
This is incorrect. The passive says "20% more chance to Evade Attacks while not on full Energy Shield". This may seem pedantic, but given that wording is very specific in some cases, it's not a good idea to use quote marks around something that isn't actually the text used in the game.

Completed 4 Challengeswedontcare wrote:
On the wiki it states it being when you are on full ES, with the passive saying vice versa.
I have no idea what you mean by this. The wiki page for the passive shows the correct stat, and the history of that wiki page does not appeat to show it ever having being wrong. Regardless, the wiki is sometimes inaccurate, and should never be trusted over actual mechanical text in the game.
"
Completed 4 Challengeswedontcare wrote:
I'm curious because it doesn't seem to be doing either of those things. At full ES I have 48% chance to evade
This is incorrect. That's fundamentally not how evasion works. I'm assuming you're looking at the Estiamted chance to evade shown in the character panel. This is an estimate, based on the accuracy rating of an average monster of your level.
Your character does not ever have a specific chance to evade. Chance to evade is different for different hits, determined by comparing your evasion to the attacker's accuracy, not a fixed global value on the character.
"
Completed 4 Challengeswedontcare wrote:
and then upon taking damage, I see no change in that number, either going down or up. Is this tied to a stat that isn't visible to the player?
Technically no, in that it's tied to your actual chance to evade each hit you take, which isn't (and can' be) shown to the player, but is not a stat (because it must be calculated for each hit).
"
Completed 4 Challengeswedontcare wrote:
If so, would that make my chance to evade an inaccurate percentage to look at for the purpose of whether or not this passive is working?
The Estimated chance to evade shown in the character panel is inaccurate for any pupose. It can give a rough idea of how evady you're likely to be against monsters of the same level as you, but no more than that.
That said, this modifier to chance to evade should in theory apply both to your actual chance to evade, and to the estimate stat (which are entirely separate things). This is a (display only) bug, which I will investigate.

Of course. The projectile loses pierce chance, so anything calculated based on that pierce chance also changes.

Is there radius limitation on the Taunt effect? I.e. does the taunter have to be within a certain distance for the taunted monster to target the taunter?
No. However, if the taunter is outside the monster's aggro radius, they're an invalid target, meaning the monster has no targets to choose from (since objects that aren't the taunter can't be targeted).

1) is there any difference between scolds / heartbound loop damage taken, and between hiltless "reflected" damage?
Yes.
"
The_x_ile wrote:
if so.. where exactly? (aside from the fact that the reflected damage can be blocked/ dodged etc..)
The primary difference is that the reflected damage is reflected damage, which carries a whole bunch of rules baggage. Reflected damage cannot trigger on-hit effects, for example. The other two are just hits of regular secondary damage you deal to yourself. They are more different than they are similar.

in my COLB build i have no idea why my mana cost is as it is... care to explain how i reach 669 mana there? (tried diff stuff and nothing lead me to 669 mana)
You've made two errors I can see in your post - you list a mulitplier of 150% for WED support, when the actual value is 140%, and you treat Reduced Mana support as having a 75% mana multiplier, which it does not - it has no mana multiplier, but aplies the stat "reduced mana cost" to supported skills. Being a reduction, this is additive with the "increased mana cost" from your jewels.
The mana multipliers total to a 942% total multiplier, to the base cost of 15. This then has a 375% increased applied (400% increased from jewels - 75% reduced from RM support), giving the total of 699. (Note that each step of this process uses integer maths, so any fractional parts are discarded).

No. The skill is a spell, not an attack, and is already triggered. Supporting it with a cast on trigger support gem would mean it would be cast on that trigger. Because it already has a trigger, the spell would then be disabled for having two triggers.

First Contagion is added to the monsters, then Essence Drain. If they were not already under the effect of debuffs, contagion will be the "first" debuff on them, until that contagion runs out.

I have a question about Abyssal Cry and its interaction with critical strikes.
When does critical strike check occurs? in a moment of initial cast or in a moment of monster exploding?
Checking whether a hit is a critical strike or not is always done when that specific hit is calculated, and cannot be done at any other time, because your critical strike chance can be different for different hits.
The critical strike roll is only made once, when the skill is cast, just like most skills. All hits from the same action have the same roll, but are potentially checking against different chances to crit, so may or may not crit on different enemies.

You only play a block animation if a hit would have stunned you if not blocked. Since you avoided the stun, the hit would not stun you, and there is no block animtion.

The diamond flask does not affect chance to crit. Chance to crit is worked out, inclduing all modifiers such as Assassin's Mark, then compared to the Crit Roll of the skill. The Diamond flask does nothing at this point, it affects when the crit roll is made, by rolling twice and taking the better of the two rolls.

When do buffs affect a spell like flameblast? Say I'm using orb of storms to proc elemental overload - if the buff is triggered after I begin channeling flameblast, does it apply since it's active for the explosion? If the buff is active when channeling begins but times out before the explosion, it doesn't apply? Likewise, is crit for flameblast itself determined on explosion or when you begin channeling?

Debuffs (eg elemental equilibrium and curses) simply need to be active on explosion, right?

How is "8% reduced Elemental Damage Taken while at Maximum Endurance Charges" from the Unrelenting Juggernaut notable calculated? My initial thought was that it just removed a flat 8% from the final damage directed to the character, but it feels a lot more powerful than that in practice (which might just be me imagining things, I admit).
