I upgrade adrenaline once. Now I should have 1300 exp.Also, congratz on thread number 4 o.O
OOC: I take it's too long to change my ability, can't see how steam will be useful to my character , I'll just wait until I can get a new one and just upgrade that.
What can you get with one ability point? Is the cost of things based on tier? Does that mean I can get vampire at 500 exp?
