New Classes
PC1 The Kineticist - Originally the Warlock, inspired by the 3e one. Renamed after the 5e srd was released which had its own warlock
PC2 The Exorcist - An anti-magic fighting class, inspired by a class from a MMORPG I played
PC3 The Witch Hunter -Another anti-magic class, this one more like Solomon Kane
PC4 The Dervish - Cleric variant, basically a cleric with monk AC and worse turn undead
PC5 The Tomb Robber - An attempt at a thief replacement, since thieves are not a well balanced class, especially single class ones.
PC6 The Android - The first class I made that offers a lot of customization
PC7 The Templar - A holy warrior class for all sorts of different deities.
PC8 The Amazon Warrior - My take on the barbarian, essentially.
PC9 The Outlander - Not finished, this is a character from the real world that finds himself in a fantasy world
PC10 The Beguiler -A sleazy sort of assassin.
PC11 The Warlock -The 5th edition warlock backported, basically a magic-user type that gains its powers from making a pact with a deity or demon
PC12 The Rogue - A backport of the 3.75th edition rogue, designed to be a viable, single class thief type character
PC13 The Witch - This went through a lot of changes. Originally was like the 3rd edition sorcerer, but has a spell selection based on adjectives (fire, white, etc)
PC14 The Shadowdancer -A backport of the 3rd edition prestige class.
PC15 The Chymist -A backport of the 3.75 edition Alchemist. Name change because it's quite a bit different than traditional OSR alchemists.
PC16 The Balladeer - A do-gooder bard-cleric, inspired by the Silver John stories of Manly Wade Wellman.
PC17 The Puppeteer -A character with no real powers, except a legion of vicious puppets.
PCS1 The Shieldmaiden - A simple adaption of a 2nd edition kit into a class
