W: Demon’s Mercenary swings his scythe in a 450 unit radius all enemies hit are slowed by 60% and the next 1/2/3/4/5 auto attacks do a cleave effect of 200 unit cone in front of him, for every enemy hit he heals 2% of his maximum hp, becomes upgraded if “Scythe” is in your inventory, if upgrades all auto attacks heal him for 2% of his maximum hp, unless another weapon is active base auto attack range is 175

E: Demon’s Mercenary cleaves an area of 350 units in front of him with his broadsword knocking all enemies back 100 units and the next 1/2/3/4/5 auto attacks deal an extra 15% of bonus AD and 5% of damage becomes true damage, becomes upgraded if “Broadsword” is in your inventory, if upgraded all auto attacks deal an extra 25% of bonus AD

Ult: i have no idea at all

i am developing a lore involving how he gets his weapons but i would like to hear from a rioter what can be changed to make it more balanced or more complex in a good way, i really hope this helps them create a champion and would love if i got some responses as to how to improve this

i don't mind answering anything that may confuse you
