Unemployed SMP Magic Skill Balance

Install this ZIP in World/datapacks/ on the server. Back up the world first.

Attribute reward changes: spell power x0.60, cooldown reduction x0.40, mana regeneration x0.70. Other rewards unchanged.
This modifies the skill tree, NOT the base spell damage. Set base spell damage separately if desired.

WARNING: Test on a COPY of the world first, particularly already-unlocked skills, to verify attribute refresh.
