>>20791025That was my DM's idea. It was a mix of good ol' 3.5 edition and Baldur's Gate 2 kits.
To make it simple, you take a three-form line and every 15 levels it evolves (at lv 25 for only two forms lines)
For exemple, Forakie starts at lv 1 as a basic Rogue/thief, then at lv 15 it evolves into Frogadier and has the option to stay as a regular rogue/thief or to become an Assassin, a swashbuckler or a Bounty Hunter. Then at lv 30 it becomes a Greninja and gains access to prestige classes.
Pokémon powers were like spells (arcane or divine), competences or weapons. For exemple, Recover acts like a healing spell, most attacks count as offensive spells and Greninja's Water Shuriken was one of its weapons.
