The changes made to the perk trees mean that previously worthless skill trees now have meaning: the most clear difference is that of the speechcraft tree, which gives perks for stamina use and shouts. The player has the ability to change which skill tree 'auto-perk' via a configurable MCN menu provided by SkyUI. Perk points are now earned on every second level, rather than every level as in base game and all skill trees have automatic perks earned when skills reach specific levels (25,50,75,100).
SPERG makes changes to every perk tree and changes how the Dragonborn levels. It was created by seorin and completely redesigns the perk trees and makes changes to how perk points and levels are obtained throughout the game. SPERG, sometimes referred to as Skyrim Perk Enhancements and Rebalanced Gameplay, is a gameplay enhancement mod for The Elder Scrolls V: Skyrim.
