As the name suggests, Iron Spells n Spellbooks Dynamic Skill Trees Mod is a bridge between the Iron’s Spells ‘n Spellbooks mod and the Pufferfish’s Skills mod, both of which are very popular. While Iron’s Spells ‘n Spellbooks introduces magic into the game, while Pufferfish’s Skills mod introduces a skill based progression system. With this mod, features from both mods are combined to provide a system to progress through magical abilities.
