The idea came from when I was switching weps really fast. So the order and combinations cause different spells to be cast. Depending on the goodness of the spell more switches are needed. For example bow, dagger 1h makes an ice floor (makes everyones pings worse in an area). Spells can only be used if you have the required weps and a magic stone. The magic stone however nerfs your armor by 50%. Whenever you cast a spell you temporarily get bad ping (seriously, getting bad ping gets makes me feel like I just got a headache) and a poof of smoke from the flintlock appears.
Ideas for spells:
Dome appears around you so they can't escape, ice floor, smokescreen, the other team sees a banner over your head, horse stampede swarm, counter spells, mind travel to an enemy, slash the air which becomes a projectile, make a tree fall over, make a decoy that you can control like an RC car, freeze someone else if you freeze yourself, poison blade, summon npcs, disguise as a tree, reverse the keys of your enemy, summon a healing tent with a doctor, autokill from behind, attack when it looks like you're still and vice versa.
