Eon, the embodiement of darkness (champion concept, AD fighter and AP mage at same time)

SO i had the idea of AD fighter that could transform from AD to AP, i know it would be hard to balance, but i thought it would be neat idea

He would have 2 forms, first is his "normal"(human form), or AD fighter (melee), second would be his stronger Primal (unleashed) form, with AP abilities (ranged)

passive: Eon does not use mana, he gains 1/3/5(depends on ult rank) shadow essence(100/150/200), everytime he kills a minion or 5/10/15 when he damages enemy champion, all essence is lost on death, eon also cannot criticaly strike (no 1000 AD crit and next second 700 AP damage), but gain 1 ad for every 2 essence he has (or something like that)

Q:normal mode: cost: 25 health Fires a shadow blast in a direction hitting 3 enemies (dealing and scalin with AD) "shadow altar" bonus: fire one additional blast dealing 50% less damage if hit by both strikes however the target get stunned for 1 sec

Q: (primal form) costs: 25 shadow essence creates a 3 wave shockblasts (like 3 circles one after another) that explodes individualy (dealing ap damage and scaling with ap) (closest first etc) dealing damage, if enemy gets hit by more than one he takes 50% less damage, but is slowed by 60% Shadow altar bonus: instead of slow its stuns target

W: (normal mode) no cost (has high coldown, but can store 2 charges, only one can be active at a time) creates a shadow altar at targeted location, creating area around it, eon gains bonus AD and AS fighting in area and spells get enhanced, however it gets destroyed if Eons move away for too long or by enemy AA

W:(Pimal mode) cost 25 shadow essence Summons a giant hand from the ground after brief delay dealing moderate damage(ap scaling and damage) and if enemy stands in the center its knocked up shadow altar bonus: if cast inside radious it tosses enemy slightly into direction of the shrine

E:(normal form): cost 40 health Eon dashes towards shrine if in its range, "pinning" any champion he collides with dealing small amount of AD damage, if enemy collides into a wall or enemy champion it gets stunned (both if it hits champion)

E:(primal form) cost 25 essence Eon chanells briefly, and then fires a shadow projectile int the targeted area dealing moderate AP damage, if shot thorugh altar it gains both damage and distance it can travel

Ulti: (normal form) when eon is at FULL essence he can then transform into his primal form (120/90/60 sec cd bettwen casts no matter the essence) gaining AP based on his AD (1:1/1:1.2/1:1.5 ratio, he losses all but his base AD tho) loosing passive damage boost, keeping altar bonus damage and gains new ablilites

Ulti (Primal form): Eon immobilizes itself being unable to move or cast other ablilites, firing shadowprojectiles in rapid fire fasison, each shot costing 5 essence and dealing small damage (similar to corki rockets), if inside shadow altar range is greatly increased, ulti can be canceled manualy or by getting hard CCed or diying (duh). If Eon falls under 25 essence, and is not in his ultimate he reverts back to his "normal form".

note that Eon has to be in Altar range for ablities to be empowered not ablities he cast (unles its his E)

sorry for any spelling errors, and i would apreciate any feedback
