It’s almost useless for most situations. The blink ability is too short range to be meaningful, and one turn of invisibilty is useless, no actual time to do anything.
The previous ability (several turns of invisibility) was actually super useful, you could use it to reposition, escape tricky situations, close distance on ranged foes, or get out of range of the deathgaze as it powered up.
But with a short range blink and one turn of invis, all you are left with is a very limited reposition. I invariably find that any place I can actually blink to is still a place of danger, still in range of whatever ranged attacks I am trying to evade, and the single turn of invis is not enough to even step through a door out of sight. The very next turn you are visible again, and taking damage from ranged attacks or hit by the deathgaze or whatever. It becomes a pointless ability, and I find I no longer even use it.
Evan, I beg you to reconsider this change. Even if you got like 3-5 turns of invisibilty after the blink it would be useful. As it stands, it makes using dirk/assassin’s blade for Duelist utterly useless. Feels so horriby nerfed as to no longer be an option, which is a shame, because it was such a fun option for Duelist.
Dagger used to be a secondry life-saving weapon because of it’s long invisiblity, the new ability is just 0-damage combat ability compared to it
EDIT: It also made tansmuting the rapier interesting because it gave you a chance to get the best invisiblity dagger, which was unique change compared to the classical “Save SoT for high level artifacts”
