I'm suggesting other damage types such as that have a sort of tri-strength/weakness. Making them more effective against 3 monster groups instead of just 2.
For example
Blunt Damage:
Strong against: constructs, gremlin, and beasts
Weak versus: slime, undead, and fiends
Weapons would be:
Close Range: maces, morning stars, clubs, and hammers
Long Ranges: hand cannons and shotguns
The bonus would not be as strong as using shadow damage vs gremlins, but better than using normal. Same goes for the weakness, it's weaker than normal but stronger than a monster's resistance type.
This would help add variety to player equipment.
I've also noticed a lack of weapon types in general. This might just be a early stages of the game thing, but it would be nice to see a greater variety of weapons in the existing damage types like:
Normal: axes, halberds
Piercing: spears, lances
Elemental: scimitars
Shadow: daggers, scythes
It seems a sword and a 1-handed weapon is integral to the game so I'm not going to suggest dual wielding or two handed weapons (although they would be neat and add a lot more variety to dungeon runs and play styles).
blunt damage would be filed under normal damage imo
we have a shotgun LIKE gun but its not that good hand cannon, no...
