[Champion concept] Madin, the broken warrior

here is a concept for the champion Madin, a melee fighter dual wielding swords dealing alot of sustained damage

Passive: Rising power Every spellcast generates a stack of Rising power for 5 seconds, increasing mana costs on his basic spells but also lowering their cooldowns after their next cast, stacking up to 3 times. If Madin has no mana left to cast a spell, he will use health instead

Hovering Blade Madin spins around creating a hovering blade dealing damage to any nearby units every time an enemy unit touches it. After 1 second it can be reactivated flying in the targeted direction dealing damage to enemies in its path. Unactivated blades will remain hovering at their location for 2 additional seconds Uncontrollable Power boost: every time the blade hits an enemy it will create another blade hovering at the center of the unit that it hit.

W: Dark force All attacks within a short period of time after cast will deal bonus damage and attack at 1.75 attackspeed (this cannot be boosted or lowered) Madin will be healed for a percentage of his maximum health on cast and at the end of the duration Uncontrollable Power boost: the bonus damage is applied in an area of effect, it will automatically be active for the full duration of Uncontrollable Power.

E: Explosive bash Madin dashes forward dealing damage to every unit in his path, stunning minions and non-epic monsters for 2 seconds. If an enemy champion is near your landing location, you will instantly attack them stunning them for 1 second. Uncontrollable Power boost: If the dash hits a wall, minion or monster Madin will take it with him, exploding it on hitting an enemy champion, lowering their armor and magic resist for 5 seconds.

R: Uncontrollable Power: Madin Deals damage in an area of effect and gains bonus armor, magic resist, attack damage, health regen and health, removes his mana costs and empowers his abilities for 15 seconds. After those 15 seconds expire Madin will be extremely weak for 5 seconds afterwards, making him take 25% of his maximum health in true damage every hit.
