I personally think that void jump is too Op~ i mean look at Doranbalt (The FT mind trickster and council executive), he just uses teleportation and kicks many asses while doing that!
I would like a slow dissolving~ i mean teleportation also tends to meta gaming~ Not that i will have a last word about but still~ It allows you to evade very attack while also making direct counter attacks! Sure we should be powerfull~ but her other abilities are strong enough in my opinion!
