it’s .75 in-game, haven’t found that one so far. don’t judge me yet, i’m just looking around for things. 
and is the devotion skill activation chance per cooldown mechanic somewhere i have overlooked so far?
also which one is the floor-is-lava-mechanic: hotspot_buff which has crazy high aether damage or wraithwind_buff which has vit + life% damages?
Cooldowns are listed per skill, they can obey or ignore the global skill cooldown modifier too.
Most caps are “exposed” and in many cases a min/max is set per item that modifies it. It is probably exposed, but look at some items that modify it first.
I think there are 8 or something “floor is lava” mechanics and they do different kinds of damage, often as a percentage of life.
