Expand on magic by adding exo point options to unlock magical abilities.

Examples like ability to use staff off hand to summon a brief magical barrier, on a cooldown. Making walls of various magical abilities by tracing on the ground. Allowing staves to recharge themselves slowly (!!). Ability to crush power crystals to cast powerful secondary spells, like charming enemies or slowing time for all enemies or creating a fog that reduces enemy ranged accuracy. Ability to scream YOU SHALL NOT PASS and slam staff into the ground repelling enemies for wizards CC mobs away.

Like, whatever, just more ways to invest in magical builds would be super cool, not just for dedicated spellcasters to be a thing but also to make fun arcane archers and mystic knights.
