Swords/melee weapons
- Hrunting
- Caladbolg
- Excalipoor
- Dragon Sword (Ninja Gaiden)
- Tyrfing; could possibly deal extra damage to players
- Claiomh Solais (does not have to be the one from the Aria/Dawn of Sorrow games)
- Terminus Est (from SotN). Could cause poison (or deal poison "elemental" damage)
- Lance/Spear of Longinus (Holy Lance in many Final Fantasy games).
- Vampire Killer. Could be any incarnation of the whip, from the simple leather version, to one wreathed in flame, to the full length morning star from IV, etc.
I think I'm done with weapons for now. I'll edit/reply if I think of any other items. I seem to be having trouble thinking of armor and other items. :p
