Is the mask of eee worth it on a chief or vet was thinking that and berserker blade would be tempting
I use it on my heroes to chase the goblins and skaven, it has worked nicely so far, and it takes out the fear from other units (not that lizardmen need that though).
It paid off big for me on a Chief in a Skink unit against Skaven. He ignored the flanking unit of 24 until to late. Rat ogres with WS 1 and Saurus to the front did not fare well. His horde even less so.
