Here is a few good ideas. That might put the magic back in the game we know, and love.
Bagdes give points to wizard.
if the bagdes give us points like trainging for spells, but point to get health, mana, stun block, critrical, or critcal block would be better.
We could use crowns to buy them back like in the gloem tower. The zebra there would be the perfect guy to bring the concept of this or buy them back for us.
