Yeah for gameplay purposes the character would be out of harm’s way, I just don’t want to get bandit blood on the flag :p , also sword combo looks cool.
Maybe if it were an offensive shield? A pike-thrust instead of SWall/Bash, with a free hand for a light weapon. The banner would restrict secondary weapon choice and the “pike” hitChance could be reduced when paired with another weapon. Might make them a bit more sturdy.
Regardless, the spear heads you have on some on the banners sell their added utility, and I suppose they could all have spiked bottoms.
