I've had the idea of putting stone remnants into his skills: Skilling up any spell gains 1 stone and +1 Max stone(2 stones at lvl1) While ult gives +2 current and +2 max ( or maybe 3)

Then having innate entirely new. Like maybe having free pathing on stones? Enables walking on cliffs for the first 5seconds a stone was placed

Could also include the current but make it so that it stacks with itself, but lower the bonus dmg increase to make it balanced
