Ok, but so I have to make a clarification. This homebrew class is able to "purchase" some upgrades when it levels up. One upgrade let you learn a 7th spell (once a day) and another upgrade lets you an 8th. Also, another upgrade increases the slot amount of the higher slot by one. Another upgrade increases the slot amount of the lower slot by one (can be bought twice). Of course, there are more purchases, so you must choose focus on magic instead of another stuff like tank, warrior or tactic choices
