This is probably just one of my stupid ideas but... it might be cool if you could use both hands while using a single one hand weapon with no magic. So basically you could wield a larger broadsword (like the elven sword in OB) with both hands for more damage and maybe some different effects like knock back and not staggering as often when blocking compared to blocking with just a weapon normally. This likely wouldn't make sense for maces and especially daggers in most cases, but it may be cool for swords.
Well...if that made any sense, your thoughts? Also if this is really stupid or has been asked before... my bad
