Plane of Force:
For the purposes of proficiency, this counts as a Long Sword, Battle Axe, or Scimitar. Select which whenever you pick it up.
Reach: Melee
Damage: 1d20 slashing damage per 6 levels. Strength modifier still applies. Cannot be wielded with more than one hand.
Critical Hit: 18-20 x2
Special:
A Plane of Force ignores Natural Armor and Non-Magical Armor/Shields.
A Plane of Force ignores hardness and bypasses material damage reduction.
On a confirmed critical threat(roll to confirm even against a creature immune to critical hits) the creature struck must pass a fortitude save or lose a limb as if the weapon had the Sharpness special quality.
A Plane of Force is a Force affect and thus can strike Incorporeal and Ethereal targets without the miss chance normally inherent in attacking something Incorporeal or Ethereal.
Amphisbaena:
For the purposes of proficiency, this counts as a morning star or a spiked chain. Select which whenever you pick it up.
Reach(M): 5’-10’ threatens
Damage: 1d6 piercing damage per 2 levels.
Critical Hit: 18-20 x2
Special:
Two Headed: Can be used as a double weapon with 5’ reach.
Poison: Initial and Secondary Damage is 1d6 Con per 4 levels; Fort Save DC10+½ HD+½ BAB.
Death Gaze: During the Full Moon you can aim the two heads of the snake as a full-round action and force any 2 creatures within 30ft. to make a Fort Save(DC10+½ HD+Cha Mod) or die. When not under the full moon you can use this power to Confuse instead of kill. The snake’s lantern-like eyes also function as a pair of bullseye lanterns that require no oil and can be used under water.
Bite Footprints*: You can attack the ground in any square a creature moved through on their last turn in order to inflict base weapon damage, but not poison, on that creature. You can also harm a creature in this manner if you have a clear and complete footprint belonging to the target, regardless of how old it is or how far away the creature is.
Spit Venom: As a Swift action you may take a ranged touch attack against any two creatures within 30ft., if you succeed these creatures are blinded for one minute.
*I didn’t find any reference to this in the mythology, though I didn’t look very hard, but I’m including it because angelfromanotherpin suggested it.
This is a really cool idea Koumei had and more people should contribute.
