Current Ideas and Planning:
Claw Weapons: Dagger like weapons, stand slightly between Short Sword and Dagger. Do more damage.
Whip Variants: Whips made of things like sinew and muscle tissues. Also include bladed whips like Scourges or Urumi
New Shield Types: Though most people don't use them, lighter versions of shields that aren't as cumbersome.
Two Handed Maces and Great Mauls: Massive weapons on par with the Great Axe.
Armor Splitter: Massive (and heavy) weapons that hold the Vacuum Blade effect.
Enemy Types:
Enhanced mistresses that use the new bladed whips, they're a nightmare for other mistresses. Can probably do something with friend/enemy relations to make mistresses not like them as much. (Some form of monster infighting? Though, since they're masochistic, they'd probably not have an issue with it...)
Rats Of Unusual Size. Larger and more dangerous rats.
Enemies made of fluids: Enemies of fluids that are obviously extremely dangerous to equipment. Some have their benefits.. Others. (High speed acid baths anyone?)
New Unique Enemies
Violent Valse: A human character who wields dagger and tip-sword. High speed, light armor.
Karroth The Butcher: High arm strength, might wield some intensely strong two handed axe that is pre-rusted.
Grand Assassin Marsical: A contracted killer from a distant land, comes after the player wielding two sickles.
Spite: A unique Imp who will annoy the player by stealing items from them. If possible, will wield a unique Whip of Thievery.
Unique Armors
Thief's Harness: Increases Agility and Dexterity.
Glorious Golden Codpiece: A belt that acts as a light source.
Brawler's Cloak: A half-cape of sorts that will grant agility.
Unique Weapons
Holy Penetrator: A tip-sword made of unicorn horn with a obviously phallic name.
Portable Landmine: A shield that will explode upon block, similar to how Turox explodes upon attacking an enemy.
Unlabored Flawlessness: A wooden two handed sword of sorts that spawns as ebony or yew. Will probably always be +16. Could be dangerous.
Longevity: A whip with a vampiric effect.
