I am asking this because, in general, the tool tips in this game are largely horrible and specifically because of the tool tip for the Cryodiil's Light Set. 5 piece does "reduce damage taken by 25% while casting or channeling an ability".
What I think they mean based on other games I've played.
Channeling: having an ability do "x" over a period time and at the end of that time the ability is over. i.e. Remembrance
Casting: Instant use i.e. Breath of Life
Activation: Pressing the button and waiting "x" amount of time then the ability happens, i.e. dark flare
In this game, is casting different than channeling like the tool tip suggests? If so, what is the difference? What about a HoT or DoT? How does that factor in.?
