Alright I decided to completely redo the HUD instead of simply modifying it. The purple is mana, the green is health, and the blue is experience.
Also about the weapons, there are Axe, Spears, swords, daggers, katanas, maces, and staffs. All weapons (except the staff) have a basic version, 1-3 slot version, and rare weapon version. The staff has much lower attack and no slots but will allow you to use a skill when equipped. It also increases your mana. The rare version has 1 slot, all the skills of the other staffs, and other stuff.
Also about skills you learn each version of every skill every 11 levels so not only do you not learn your first skills till level 11, you can't learn the last skill. Unless you buy a spell book or use a staff. With a staff you have the skill as long as the staff is equipped. Spell books are permanent and extremely expensive.
