This is just a fan-made what-if character in LoL franchise, hope you enjoy it, because I'm about to make more of these!
Passive: Whenever you die with an ultimate spell activated you will be revived by a yellow orb. (This is a reference to an item from DMC games where if you have this yellow orb you will be revived!)
Q: This is a ranged AD attack where Dante stabs opponent from distance while dashing into him. (This technique gets a bigger range everytime you level up this spell!)
W: This technique allows you to flash to a selected place. (This technique gets shorter prepare for teleport everytime you level up this spell, example - if you have lvl 1 spell it will take about 3,5 sec to flash to a selected place, but if you have it max it will take about 1 sec to flash to a selected place)
E: This technique allows you to knock-up opponent whenver you're near him dealing + AD damage while knocked. (The more your spell is leveled up, the more high you can knock your opponent, so because of that it's uselful not just for you, but for your teammates too, because they can prepare they're attacks while you knocked the opponent in the air)
R: This technique buffs your basic attacks, spells AS and AD + you gain more health and you deal about 60-120 AP. (The more your spell is leveled up, the more time you can keep this form activated + bigger use of AD,AS,AP of course).
If you want to know how these spells look, just search for Dante's moveset and you should see!
