Cast on damage taken mechanics

I have a question about mentioned trigger gem. Lets consider a situation: i have 4L item, so all slots are linked and i put there cast on damage taken and 3 skills.
Now fun begins:
1) when support gem trigger, will all skills activate, or rather for each of them chance to be activated is rolled separately? So one of them can be activated, but can also be 2 of them or 3?
Other situation: i put 4 skills and 2 support gems: cast on damage taken and cast stunned, all linked together.
2) How will they behave, when requitements to activate one of them are met?
3) What will happen when requitements for both of them are met?

I'd be grateful for explanation, the more detailed the better :D

The support triggers all linked skills when you take a certain amount of damage, there's no chance involved.



On levelling the support it increases the threshold and lowers damage penalty, so you can either trigger weaker spells more often or stronger spells more rarely. A good choice.

Thanks for information :)

Does it always reliably behave like this though? Both the times I've tried it, I can't get each linked skill to trigger every time in a CwDT + 3 skill setup. Sometimes it's all three, sometimes just 1 or 2 of the linked skills trigger when the damage threshold is reached.

I made a video demonstrating, I haven't been able to get more reliable triggering than this with two different characters now. I'd love to know if I'm being stupid somehow!

Cast When Damage Taken Multiple Triggers?

It's a bug, mini-cooldown that CoDT forces on linked skills sometimes causes 2nd and 3rd skills not to activate. Nothing you can do until they rework the gem.

That's not a bug, but intentional. Cooldowns are global, and everything linked to CwDT is in the same cooldown group.
Otherwise it wouldn't really accomplish anything. The problem wasn't casting a specific skill more than four times per second, but casting 15 skills with one trigger.

Can't say, people are reporting it sometimes casts all linked skills and sometimes it doesn't. Haven't been playing much with it because it's a lame system so wouldn't know firsthand. They should fix description then to 'casts a single linked spell', can't get fucked up more than it already is.

I say just throw the damn thing out and replace it with something else, cast on block or something.

Take a look at the video that I posted though. We see all three skills fire off at once on the first trigger, proving there isn't a deliberate programmed limit. After that the skills trigger in ones and twos. The skills all have their own cooldown speeds that I put onscreen - the problem is they don't all actually trigger 100% of the time.

Another newbie question please:)

I am very confused about the nature of wording when the gem says "only supports level 31 gem or lower".

Very confused on this cause I look at others builds and they have high level gems linked to this. So they have the cast on damage at level 1, but other gems are like level 16 which would make the min req level like over 45 or so. How then would this trigger gem work.

Thanks for any replies.

It means "only supports gems with a level requirement of 31 or lower".

If someone has linked a gem with a higher level requirement to a level 1 Codt gem they are either ignorant of that or don't want to have actually liked to Codt.

edit:
I'm not entirely sure but it could be that Codt had not always the level requirement part, if that's true those builds are properly from that time.
