As of now, I can only learn three Skills out of the four there are for Invokers, but there are also the other Skills for Alchemist which I've been ignoring for a little while. However, they might be just as important in my quest for more strength. Alchemy helps me create all sorts of items the better I am with it. I could create potions to increase my stats and even to enhance my abilities. Or even other items to do a variety of new things. Even special bombs can throwing items can be created through Alchemy at higher levels. However, I've already calculated that it should be possible to learn every Skill at around Level 7 or 8. So that'll leave roughly 22 levels with free Skill Points that I can save for the next Talent. That's 220 Skill Points.
