Cannot Use Abilities in Instances
I also can’t swap weapons.
Being unable to complete the instance is an exaggeration—after a few minutes, I regain the use of my abilities.
All 3 times so far, it’s during some sort of fight.
During the thing where you have to throw bloodstones that is the only skill you are allowed. During the instance facing your fears only one person can do anything, the other loses all of their skills again. There are probably more like this. Intended, but not what I would call good design.
That sounds exactly like lag. The chat servers aren’t the same as the game servers, so it’s entirely possible for chat to work fine while your skills appear not to be firing.
If it happens again, contact support. If you know how to run pingplotter or something similar, you can start doing that before they write back
