Is that going to increase incrementally over time? Like 10 health skill it's 2 health per second. That'd be cool. Maybe a perk tree which can give you special skills. Like increased mining speed 5% with 1 point. I like point skill systems more than simple skill building systems. Like with a points based system someone could develope the skills they want to focus on,even if they are weak in that area. Say I'm bad at increasing my defense but I'm great with the bow. I could level up using the bow and put points into my defense,then i might start using my sword more,etc.
