Soul Power is the resource that allows the player to use different Tablets.
Soul Power has a max cap of 200. It has the slowest regeneration out of the resource bars, at 0.01 points per tick.
Soul Power is used to activate Tablets. Each individual tablet requires an Activation Cost of Soul Power in order to use, and once activated, drains a certain amount of Soul Power every second.
Soulfire Bow consumes Soul Power to have its arrows lifesteal from targets.
