Simpler class trees
Changed
- Knight and Archer now each have one cohesive eight-skill tree, matching Mage. Abilities from the second path continue as later tiers, while the third paths have been removed.
- When a class has a single tree, the Library now shows its skills directly without a redundant weapon-name button.
Fixed
- Butterfly once again uses Rain of Arrows, and editing its stats no longer removes the assigned ability.
