Garian's battle skill tool tip is not accurate, it takes longer to go through a cycle than is stated. It looks like the timer did not take the animation into account, causing it to be slower than stated.
This is frustrating because I used resources to level him up, and level up the Ancestor's Candle specifically to time Garian's battle skill.
I have posted a video to try to show the problem. My Garian has a 9.7 second Battle skill cooldown. The Ancestor's Candle is at level 16 giving a 9% time reduction to the Battle skill. This means the Battle skill should recharge in 8.827 seconds, enough to get 2 rotations in the time the boss does 1 full rotation (18 seconds for Tawler).
However, the video shows Garian is late with his battle skill at about 1:47 on the video, or at about 3:46 on the in game battle screen.
This is frustrating wasting resources because the game does not accurately show the skill's cooldown. I never would have leveled the artifact up, Garian, or used the scrolls and wyrmarrow on him if I knew this was not an accurate description of his skill timing.
Is there any way to get my resources back, or to make his skill accurately cast at the time stated in the tool tip?
