I always find it time-consuming to switch back and forth between pages on the Path of Exile Wiki to find out which level is the optimal one for all the gems I link in my various CWDT setups while planning out my builds. I've posted this on Reddit but I think it might be useful to post it here as well.

Trigger order : Trigger gems and their linked skills are cast in a certain order that depends both on which item it is equipped on and which socket the skills are in.

When a linked spell is cast, it is put on cooldown for ms and will not track damage during that time.

All damage counters will be reset to 0 upon entering a new area. The effect ends when you have 1 life remaining. Your spell damage is substantially increased while under this effect. Damage counter and cooldown : Each linked spell gains an internal damage counter that tracks the total accumulated damage taken from hitsthough not from damage over time or the Blood Magic passive e. Multiple copies of Cast when Damage Taken will also function independently. Multiple spells can be linked to a single trigger gem, and will all be triggered if so.
