say you have a hammerskald in a chariot and there are opposing figs in b2b conact with the back and sides of the chariot can you sweep all of the opposing figs in b2b with the back and sides?

I done it with Maelstrom Golem

so can the hammerskald sweep all sides

A passenger's front arc is considered to be the side and rear sections of the chariot.

Sweep allows the figure to simultaneously attack all figures in its front arc.

In other words, yes.

why not save a few points and use an axe-knight? (I dont have a hammerskald) also, would putting someone with polearm follow the same ruleset?

Can't wait to try that out with my Atlantis Ram (only chariot i got for now) and my gate lord!

I play high point games :D
