Wand of Geb is usable if you either:
A. Have nothing else
B. Want to shoot around corners and lack a sprite wand
C. Same as B but instead the corner is too far away from the entrance for a sprite wand
D. Want to be the ultimate support class (since the dungeon uses test chests, the set wouldn’t be nearly as bad when in a shatts)
But yes, it is still terrible and needs a buff
