Another random pvp idea: each knight gets a wooden heavy sword. Multiple energy balls will appear on the map. The objetive would be to hit said balls, sending them towards the enemy. You'll also get a shield that can save you if used properly but regenerates very slowly.Shields deflects attacks on a random direction.

The more hits a ball acumulates, the faster it'll go until it kills a player and slows down. You can also charge your sword to give an extra temporary boost to the speed of the ball.Charged balls cannot be shielded.

Armor bonuses will be removed too and some boosts will appear on the map, like in blast network (+ move speed, CTR, ASI, shield regeneration, etc).

I'm thinking of a free for all big cage match, but the idea could also work for small teams or 1vs1 (with bigger teams a lot of coordination would be required). Also the maps could have some traps or switches that raise hidden walls,etc.
