Cast on Damage Taken

Hey all, just had several questions about this, as I have not found one yet.

1) Does it respect cooldowns

2) Does the cast spell cost mana?

3) Can I use copies of the same gem to cast multiple times when damage taken? (ex, 3x fireball)

4) Is the target of the spell always the mob that dealt the damage

5) Is the "on damage taken" before mitigation, or after? (ie, 400 gross damage, or 400 net damage)

6) Not essential to answer...but can reflect proc this? If the spell does enough damage that reflect procs it, wouldn't that lead to infinite casts until either you or the mob dies?

Answers to any of the above are appreciated!


Edit - Thanks for the answers so far, but it seems like people don't agree about #1, which is a key for me. If I get cast when damage taken on three different items, linked with enduring cry, will I get it to cast three times, or only once?

6) not sure

1) yes
2)no
3)not sure. most use it for enduring cry/molten shell which cant be multicast anyway
4) hard to say if it is enemy that dealt damage or closest enemy
5)gross I believe. It procs for me and my health doesn't move

Your number 2 is wrong. The Trigger costs NO mana for the spells attached!

Sorry, just wanted to make sure

If you all are saying that the gems can't be the same(Question 3)

From what I had seen, for Molten Shield & Enduring Cry, even though they are multi-casted, they will still remain the same(eg: 10 sec/max amount of endurance charges)

Correct me if I'm wrong

You will cast them at once at the same time when damage threshold reached.

Not sure if this is what you mean.

Nice questions, I had been asking myself the same things. Another thing I'm going to try this week that I'm not entirely sure that works is:

Getting 2 Enduring Cry and using one linked to CODT and one independent from that so I can spam it.

Anyone knows if it works?

1)no
2) no
3) no
4) who deal dmg
5) befor(check molten shell desr and different lvl)
6) when you getting dmg via reflect it procs

yes ofc(didnt played really for a long time but cold snap traps and other stuff was able to abuse like this so im sure there different cd and spell)

also that ppl doesnt notice really all hits have right now a 0.35 sec delay
same as your ST cant hit one target in one time you cant make a loop with dmg taken( or any other autocast)

Look at his videos and his gem-linkings, I'hv tried it on my own too, although its kinda hard to see with EK, but, placing multiple same gems is available

Hi Guys,

sorry when this is a necro, but I found that thread via google, and it still does not answer my questions completely, so I thought I just add this here. :)

so as far as I understand it (also according the wiki), it cannot spam spells which have a cooldown, and more importantly, if the spell is on cooldown, it does not count towards the threshold:

http://pathofexile.gamepedia.com/Cast_when_Damage_Taken
Cooldown: Cast when Damage Taken has a cooldown of 250ms, or the linked skill's cooldown, whichever is longer. Each linked spell has its own cooldown and internal damage counter. The damage counter will not increase while the spell is cooling down.

I was surprised the answers here in this thread were different...

so, I take 440 dmg (at gem lvl 1), for example enduring cry (4 sec cd) triggers, now I continue to take damage (maybe some additional spells trigger, because every spell has its own counter), but the counter is "on hold", enduring cry CD finishes, and from now on I have to take another 440 damage so it triggers again.
1) am I correct with that?

the next thing is: I use blood magic gem for my main spell, and that spell costs 42 health because of that.
now I took 400 damage, and then I use that spell.
2) does cast when damage taken now trigger my linked spell, or do I still need to take that remaining 40 damage through mobs actually damaging me?
2.1) how about blood rage? I take 4% of my life as chaos damage per second because of that. I have 3600 hp, this is 144 damage per second. does this count towards the cast when damage taken damage counter? Or is it - again - only damage taken from mobs?

3) I run two auras combined with reduced mana (grace & hatred), and my remaining mana is I believe 58.
Do spells cast by cast when damage taken cost mana? If not (which most people, also in this thread here state), does the fact that if a spell would cost more mana than I have left (for example, my warlord's mark, which would cost 66) has any effect on that? such as, well it would not cost mana because of the trigger gem, but in theory it would not be able to be cast (not enough mana), so the trigger gem can't cast it either?

Thanks for any feedback on this :)
