I am still learning the game rules, let alone adding any self-imposed restrictions! It took me hours to figure out how to dual-wield attack using the bonus action. I also just learned how to use the Throw action with a javelin. There are so many little action icons that are easy to miss.
One thing I am self-imposing now, and only because this came up in another thread last week, is the ability for a multi-class Spell Caster X / Wizard Level 1 to learn and cast every wizard spell in the game. For example, right now a Cleric 11 / Wizard 1 multi can cast any wizard spell up to the 6th level. That's just bad, and its wrong ... it's "badong" (ref. Kentucky Fried Movie). Maybe Larian will add the Arcana cleric domain someday.
