The skill Pauru is constantly greyed out in T3 NM cube after you cast it, and this may be the case in other content too, but so far only things I’ve done are chaos dungeons. Night Fox Yoho, Deskaluda, Cube and Boss Rush on this character, all of which don’t have this issue except Cube.
Cant say ive tried. But to be honest im not keen to since even as a Main Co build i use a Chaos dungeon build for Cube. The pets are pretty bad vs. multiple enemies.
Maybe someone else has had some experience?
Never tried pauru in any places. Maybe you should try bring this to bug and feedback session?
Personally i use chaos build for cubes and switch the special summon to akir when boss comes.
