Lod skeletal mages

i saw in maxroll guide trag’oul corroded fang in the cube, why? i don’t get it, with lod mages you don’t apply any curses

Looks like an oversight? Some of the variants use Frailty so they forgot to change the cube powers.

Are you talking about the group speed build? I suppose the curse could be applied by others in the group.

The solo push build guide does have Frailty in its configuration.
