Maybe this has been suggested before but I would say a lot of wizards would like to have another amulet. One amulet that gives a spell and another that is a mastery amulet.
It would be nice if we had an item that allowed us to have another amulet spot. I would suggest a ring or athame that instead of giving health or mana, gives us another spot of amulet. That way, it is up to the player to choose whether they would use another amulet for more item cards as strategy or more health and mana as strategy. That way, it is still fair for all players and we have more choice of items to use for our strategy!
The Amulet Spot Ring/Athame can be 5000 crown in the crown shop and 100 000 gold.
I feel like maybe that slot should be inherit, or by quest or something, but not by buying it. For example, remember how we got potions one by one, at certain levels? It could be something like that. Or like a reward for a Zeke quest, or a recipe, or a crafting quest. Something like that lol.
