■ Raised max level for characters. (150 not high enough then)
■ New potions.
■ Even more new medals.
■ New weapon skill(s)?
■ Smithy improved, adding several new options. "Delete Skill", "Check skills (before crafting)", and add "Sale weapons"
■ More information available during Adventure Mode. Total damage is visible, and you can now restart the mission without going back to the map. (about damn time)
