Add a book to runemages where you can store X number of spells in order to use in battle.
Lets say you like using runemage (because magic duh) but you are kinda mediocre with casting, and even with a 50% success rate you still die very easy in a battle because of the sorta low damage of level 1-2 spells, along with the added stress of casting in a battle, wouldnt you like to have a way of charging up something that would give you the spell, instead of drawing it over and over to fail and die?
My suggestion would be a way of drawing up runes that you can save somewhere (book) where you can later on remove from the book or whatever, to instantly have the spell available.
Idea: you are prepping in your house for a battle, getting your potions ready, and your gear ready, and you can draw 5 runes and save in your notebook for the fight ahead, something like a lv 3 fire, a level 2 affliction, and the rest lv 3 frost, which you can quickly use on a boss, once the boss has been taken down, your team can clear out trash as you stay behind drawing more spells to add to your book for the next battle.
I think this is cool, but I would love to hear what the community has to say about something like this.
