Although more likely to be for an OSE game, this is something that I was thinking of implementing for a 2e game.
- Classes are all available to everyone.
- Multiclassing is available for everyone, as is dual classing.
- Humans now have a racial adjustment (I'll use the OSE adjustments for simplicity).
- A 10% xp bonus is applied for following an archetype, stacking with prime requisite.
- Humans get the bonus if single classed. They continue to gain the bonus if dual-classing.
- Elves get the bonus if a ranger or if a fighter/mage.
- Halflings get the bonus if a single classed thief or acrobat.
- Dwarves get the bonus if a single classed fighter or a fighter/cleric
This means that a human fighter with 16 strength would gain a +20% bonus to earned xp, as would a dwarf fighter. An elf fighter/mage with a strength of 11 and intelligence of 16 would gain a +10% bonus to fighter experience and a +20% bonus to their wizard experience, though I'm also tempted to merge multiclasses into a single class, combining the xp for each level together but that would change how prime requisites work.
