I dont know if these are even being used anymore? But this was my idea for something the game is noticeably lacking, a powerful non-support female assassin. Also uses some of the underutilised skills within the game so as to encourage different playstyles and builds and counters and everything 
Most of the new demigod ideas seemed quite a bit op when fully upgraded. I tried to make it so that maia cannot be fully upgraded in everything, and so is specialised in some areas but weak in others.
Also tried to make the spell names original so they arent confused with others.
Any balancing ideas will be greatly appreciated. Especially mana costs and cast times for balance.
(btw will try to include mostly non-winged pictures, as i realise regulus seems to have the monopoly on wings.)

[Name]: Maia
[Allignment]: Assassin. Potentially light, but perhaps dark. Not sure.
[Appearance]: 2 modes.
Human mode : Powerfully built female, with long flowing hair, armed with a specially designed halbered and wearing a suit of celestial-based (fancy future looking) armour. Also a metallic visor over the face, and fancy gladitorial boots.
Celestial mode : Emits an aura of pink/blue/white. Black celestial wings spawn from the either side of the visor out behind the head. Armour radiates/glows in certain areas. Halberd has a trail of pink/white/blue energy following it as it swipes.

[Strengths]:
Normal attack begins with slight aoe dmg and can be upgraded.
Can become good against mana dependant demigods.
Human abilities can be developed to allow for good 1v1.
Works best in a team environment.
[Weaknesses] :
Not much burst damage/nukes.
Non able to fully upgrade all abilities. Jack of all trades, or highly specialised but lacking in areas.
Most abilities not directly damaging.
Celestial form not so good at direct damage.

[Background] : (to be improved/added to)
Maia was a girl born into great prestige, and that great things were expected of. She was born the last daughter of the chiefess of the valkyrie Narmoth, and so her destiny was apparently set since birth. She too would be a valkyrie.
She lived with boarding schools of the ways of the valkyrie since birth. She learnt of the history of her tribe, granted the ability to take on celestial form and live in the peaceful celestial plains by and with the pacifist ancient elder beings.
In return, the tribe was given one task. Recover the souls of the recently dead great earth warriors, the lands being in constant battle with many fallen heros, and nurse them to full spiritual health.
For it was that rumours amongst the villagers of the land continually circulated that the rival tribes had been at war for eternity and it would always be so , but those on the celestial plain knew better.
Their oracles predicted that one day, a nation would be born so powerful as to attempt to ascend to the heavens and overthrow the elders.
After many many years, the prince of one of the great tribes was strolling through a recent battlefield and happened accross Maia in earth form, recovering the soul of a dead hero.
He fell in love at first sight. As did she.
But he was unable to identify who she was. Attempting in vain to persuade her to marry him and come live as a queen in his lands forever, Maia denied his requests and replied that she would never be able, as it was her duty to carry out the sole task of the elders, so to remain in the celestial plain.With this, she ascended up with the recovered soul, leaving the prince in despair.
So great was the princes broken heart and instant love, that upon inheritance of his kingdom, he decided to broker peace arrangements with the other tribes. He did this by proposing a united invasion of the great celestial lands, upon which treasures where meant to be bountiless and plentiful. All he wanted was the hand of Maia, all the rest could be divided between the other tribes.
Agreeing, the tribes united and began building collossal structures to allow access to, and assault of the heavenly celestial plains. It was as the oracles had predicted.
A great battle ensued between the celestial forces and the armies of earth. When it seemed but all hope was lost for the celestial beings, they bought out the recovered souls of fallen earth heros, whom had been allowed to live in spirit form to fight this one battle. The armies of earth were paralysed in fear by the arrival of all their greatest heroes, now fighting against them. They all fled, but the prince. Defeating many, he was finally downed in a 3v1. Maia, realising the tragedy of it all, rushed to the side of the dead king, and attempted to recover his soul.
But the elder would not allow it. As the instigator of the great war of the heavens, his crime wasto have his soul destroyed forever. Maia pleaded, but it fell on deaf ears. Unable to control her distraught, she stole a mightly celestial halberd and armour, and fled the celestial plains to the earth lands, never to be seen again in the heavens.

[Abilities]:
Human mode:
1. Shroud of Darkness
Limits the vision area of the demigod it has been cast upon. Higher ranks diminish this vision by 50/75/95%. Attacks may only be allowed in range, so when cast on ranged demigods they cannot attack someone not in their vision. All casts last 4 seconds.
1. @ Lvl 15
Affected demigod regains their vision as normal, but loses all other vision of the map (as provided by the creeps other dgs etc) for 15 seconds.
2. Winged Footsteps
Celestial wings spread out from the boots of maia, granting her limited time of great speed. 10/15/20% increase for 5 seconds.
2. @lvl 15
Gives the spell area of effect for allied forces.
3. Celestial Spike
Maias halberd charges with celestial power and slashes for an almighty hit. 200/400/600/800. Upon successful hit, the power dissolves onto the enemies equipment. This reduces hp regen and mp regen by 25/40/60/90% for 5 seconds.
3.@ lvl 15
A target struck with celestial spike is immune to all positive buffs for 6 seconds.
Celestial mode:
1. Maia's Kiss
Maia blows a kiss from afar at a rival demigod. The kiss, which takes on the physical form of a love heart and blown by celestial air, breaks upon inpact into a small area. The area of effect causes an interupt, a stun for creeps of 1/2/3/5 seconds and demigods of 0.5/1/2/3 seconds and a silence for 3/4/5/6 seconds.
1. @ lvl 15
Maias kiss also grants 500 bonus armour and heals for 500 for allied demigods in the affected area.
2. Magic Mana Hammer (name?)
Maia summons a celestial gods hammer that attacks by draining mana, no damage. This can be used in 2 ways.
Against an enemy demigod : will leach against the demigod for 200/300/450/700 gaining maia the equivilant mana. As this is a leach, if the demigod only has 50 mana, maia will only gain 50 mana.
Against an allied demigod : will transfer an amout of mana to a targeted demigod. The mana cost is penalised to double the amount of mana transfered.
Mana cost/mana given
400/200 800/400 1000 1500
2. @lvl 10 and 1000
The penalty cost is removed and it becomes a straight swap.
2. @lvl 15
Using magic mana hammer on an ally will also increases their mana regen by 100% (need good numbers?) for 5 seconds.
3. Ragnarok
Sensing the impending apocalypse, maia lets out a battlecry on her special horn to signify the coming of the final battle. This ability is available from level 5. It allows for the converting of enemy creeps in the small sourrounding area to the allied side permanently. Longish cast time.
25% chance on each creep at lvl 5
50% chance at lvl 10.
3.@ lvl 15
65% chance to convert normal creeps.
75% chance to convert 75% of the ghosts of all allied fallen creatures in the surrounding area to life for a limit of 10 seconds.
Passive:
1. Normal Attack AOE damage radius increased.
The halberd attacks individual targets naturally. Each increase increases the size and scope of the aoe damage slightly.
A level 2 (like regulus) upgrade allows 50% chance of cleave in small cone area to front.
Lvl5 100 % cleave (permanent from now on) and 180degree.
lvl7 360 degrees range of attack
2. Celestial form aura
Maia's transformation into celestial form doesnt allow her as many abilities to damage opponents.
As such, celestial aura can be upgraded to recieve a 10/15/25% evasion/dodge aura. This applies only to allied demigods.

And thats it. Thoughts? Ideas?
