Casting a skill and getting hit mid-cast puts your ability on cool-down without certain skilled being casted. Which happens a lot to me as a healer. Important heals/gates could not be dropped.
I have experienced this problem when using chronomancer as well.
I am wondering if this is intentional or a bug. Would be good to get clarification on this so we know. I could see a case for it either way. If intentional, some potion or skill to prevent interrupts in casting would be cool.
Should be the same issue here:
It’s annoying and I think it should be changed but there is a special sound effect when a spell fails like this so I assume it is intentional
