My idea is based on Dekan fighter from ROHAN Online. In there dekan is human like creature which have blood of dragons in his veins.

Dragon's child origins

When Progenitor walked the Earth creating his offsprings he venture thru small city of Al-Azam. He felt strong mystical force vibrating from this city. Upon entering he saw everyone in the city are in their full health, everyone is happy and enjoying their lives. Progenitor realized it must be that mystical force which helps people, that made him curius even more. He kept looking for it when finaly he came to small hut which was surronded with gifts from people. It was house of Aureliis. The greatest healer know to humans. Progenitor himeself witness her healing a pilgrims. However it seemed every time she healed someone she abosrbs the sicknes herself, when she healed blind women she became blind herself for some time. Progenitor could not understand where such power might come from but he realized mixing it with his own will create very powerfull offspring. One that might one day take his place.

Aurion powers [each form got one extra ability, u guys can decide which should be removed]

[You can also decide wheter Luck of heros or Switch form related effects should be removed]

Aurion (same like Torch Bearer) can fight in human form (sharing power and mercy from his mother) or dragon like form (Progenitor, his father awoke power and anger of his dragon grandfathers in him)

Stats - Aurion will be assasin not general, he can benefit from stats like every assasin.

Switch form - Upon changin his form Aurion (kind of like regulus at lvl 15 poping wings) will do the following:

Aurion Dragon -> Aurion Human - at lvl 15 Aurion can heal his nearby teammates for 500hp

Aurion Human -> Aurion Dragon - at lvl 15 Aurion can damage nearby enemies for 500

10 sec cooldown before being able to change again

Luck of Heros - At level 15 Aurion can use skill which will increase probability of chance effect by 20% (for example 30% chance  to deal critical damage, with that skill it will be 50%)(maybe aura that will affect friendly units too)

Aurion human

Aurions mercy (active ability) - Aurion activates aura around himself, when friendly demigod is in range of it and being hit he recives only X% of damage, Aurion recives Y% of damage, there is also Z% chance that damage will be swapped for manaand split between Aurion and targeted ally. Affects all friendly units in range. Once activated this ability cant be switched off for 10 sec (beast spit like range)

Aurions sacrafice (targeting ability) - Aurion can sacrafice his own life force(lose hp so teammate gains it) to save companion, to that that he needs to be able to tuch his companion (say 2ft. radius like lvl one rook tower summoning) which endangers himself.

Playin style

Well it wont be easy (rotfl). It is character for expierienced players who can assume what happens when they cast abilities.This not even beta of the sketch. So I am aware it would need tweaking to make this character more balanced, I realize this character will be both mana and hp depended, but in retun offers so much(specially dragon form). Damage output from dragon form in late game would be insane, but u gotta be carefull specially with Blood Lust which got chance to stun you with little hp, thats the price for becoming almost unkillable. Mothers mercy and Aurion protection are also very powerfull and dangerus spells for you. You need to be very carefull when u decide to use them.

So u got 2 character one is ultimate support character and the other one is killing machine.

Few Last Words

Wow!! if u get this far i just got fev more things to say: Comments are welcome. Constructive coments are more then welcome.

If wanna be abusive () remember silence is gold, ducktape is silver. Thanks for reading (took me only 3 hours writing lol).

PS.> I am not native speaker sorry for misspelling, but i think it is easy to understand what i mean, and there is no point to point those out. If u saw something looking like the one i created here be sure that i was not aware of it and didnt try to copy anyones work. All skills and history is created by me.

PPS. I also included pictures of rohan Dekan to show you example how he can look like

Dekan Thanks to wikia.com
