So for a lot of characters I've made and a lot of other characters I've seen made, hammers have been almost an entirely unseen weapon choice. It really feels like just about every other weapon type has something up on the hammer; swords have better crit ranges, polearms have reach, and bows are just amazing. Sure, you might have a backup hammer for bludgeoning against skeletons/oozes, but even in APs, the weapon choice almost never includes hammers, they're rarely in treasure, and they're severely lacking when it comes to specific magical ones.
Hammers are like really cool, but a high crit multiplier doesn't really make them that good because for the most part higher crit threat ranges are better, and hammers don't even have the best crit multiplier (scythes/sickles are better for crit fishing and butterfly sting shenanigans), so there's really not a lot of base value for the hammer in most games.
Please, tell me about anything you've done to make hammers better and or awesome examples of hammer using characters you've played!
