Btw, it's possible to install a +1 skill without the need of overwriting a slot, you can just choose the option not to install it, yet it will still add an additional +1, this way you don't need to wait until it's on +30 to install all the good skills, however the skill you chose not to install will disappear afterwards. ^^
