I'll skip the introduction here, it's really not needed. I had some ideas, and figured it's time to let them out. Sure, the chances of them being utilized are fairly small, but it's better then keeping them pent up forever.
Inspiration and appearance:
This demigod's premise, in terms of combat abilities, were inspired by the Guilty Gear character 'A.B.A,' seen below.

Anyway, onto the actual Demigod. For now, I'll just call her the Shamaness.
Here's a quick drawing I did a while back that basicly sums up the general idea of the appearance. It was a really rushed sketch done on a bus, so please forget the crappy quality of the drawing. If anyone wants, I can draw another one that isn't as bad. Also, if the idea of this character catches on, I'll draw up my idea of the actual Demigod itself:

In the case of this character, the Demigod is actually not the Shamaness, but the sword. The Shamaness only acts as conduit for its power. The Demigod himself had his physical form sealed into a sword, and now requires a medium to manifest its powers. Or some crap like that. I'm a good writer, trust me, but gameplay's more important.
Anyway, here's the basic idea:
She focuses on two forms. Standard and possessed. In standard form, she is overall fairly weak. She has some decent support skills, but doesn't have the raw power to have much impact. However, by releasing the power of the sword through a ritual(skill), she can give the Demigod a physical form for a limited amount of time(transforming the Shamaness into the actual Demigod). During this period, the Demigod's attack power, speed, and movement speed increase to very high levels, however, he must sacrifice health in order to attack(to represent the strain it causes on his physical form). By using a ritual to transform back into normal form before the time limit runs out, however, the Shamaness can regain much of the health lost.
Statistics and skills:
Assassin
The Shamaness has fairly average stats across the bored, with low attack speed and attack power, and high mana and mana regen. Short of her attacking abilities and mana pool, she's not weak or strong in any area. In order to explain her armour, remember that the Shaman herself is immortal so long as the sword is alive, and thus, so long as the sword is not broken, the Shaman cannot die.
What makes the Shamaness unique, however, are her skills. She has 7 active skills, similar to Queen of Thorns and Torch Bearer.
Active Skills:
Ritual of blades(4th slot): 3 second cast time, 0 mana cost, 15 second recast. The Shamaness/Demigod performs a ritual to transform itself into its alternate form. The Demigod has greatly increased attack damage, attack speed, and movement speed, but sacrifices health whenever it attacks. The Demigod also has a seperate active skillset. When this skill is used to return to the Shamaness form, she recovers 80% of the health sacrificed while in Demigod form. Any enemies within 5m of the Shamaness/Demigod during this skill's activation take 200 damage and are slowed by 10% for 2 seconds. When alternating between forms, all buff spells casted on the Shamaness/Demigod are removed. This skill cannot be interrupted, but it can be cancelled or stunned.
Dancing Swords(Shamaness): Toggle, uses up 125/175/225/275 mana per second while active, costs 300 mana to activate, 7 second recast. The Shamaness assumes a trance begins dancing in ritualistic fashion. While dancing, the Shamaness moves 30% slower. Attacking, using skills or items, being interrupted, or being stunned will end this skill. Any allies within 15m of the Shamaness do 10/15/20/25% more damage with their normal attacks. This ability does not affect the caster.
Dancing Shields(Shamaness): Toggle, uses up 125/200/275/350 mana per second while active, costs 400 mana to activate, 7 second recast. The Shamaness begins dancing in a ritualistic fashion. While dancing, the Shamaness moves 30% slower. Attacking, using skills or items, being interrupted, or being stunned will end this skill. Any allies withing 15m of the Shamaness regain 100/200/300/400 health per second, and have 10/15/20/25% higher mana regen(from base). This ability does not affect the caster.
Blood Ritual(Shamaness): Toggle, uses up 125 mana per second while active, costs 150 mana to activate, 7 second recast. The Shamaness begins dancing in a ritualistic fashion. While dancing, the Shamaness moves 30% slower. Attacking, using skills or items, being interrupted, or being stunned will end this skill. The Shamaness loses 75/150/225/300 health per second. All enemies within 10m of the Shamaness lose health equal to that that the Shamaness loses through this skill(Bulwark of the Ages reduces the damage that the Shamaness inflicts upon herself, and thus, the damage enemies recieve).
Sword Crush(Demigod): Costs 200/300/400/500 mana, instant, 10 second recastt. The Demigod leaps at his target and slams his sword into the ground, dealing 500/800/1100/1400 damage to a single target. The Demigod recieves 30% of the damage caused by this attack(even if it misses). This damage is counted when The Demigod changes forms.
Pheonix Strike(Demigod): Costs 300/400/500 mana, instant, 12 second recast. The Demigod ignites himself and the area around him, causing 400/600/800 damage to any enemies within 7m of himself, and sending smaller enemies flying. The Demigod loses 50/100/150 health per second for 4 seconds after using this skill. This damage cannot be recovered by switching forms.
Counter(Demigod): Costs 300 mana, instant, no recast time. If this skill hits an enemy demigod casting a skill, they are stunned for 1/2.5/4 seconds, If this skill hits an enemy who is not casting a skill, then it does 100 damage, and has a 18 second recast time.
Passive Skills:
Rhythm: While using dance skills, the Shamaness' movement speed is reduced by only 20/10/0%.
Ritual Master: When the Demigod reverts to the Shamaness, he regains 90/100/110/120% health instead. Also, the damage caused by ritual of blades is increased to 300/400/500.
Inherent strengths:
Ability to switch forms, allowing versatile builds.
Shamaness form allows for great support and AoE damage.
Demigod form allows for very high damage output with fast movement.
Inherent weaknesses:
Ability to switch forms limits abilities.
Lacks any reliable self heal.
Deals damage to self in Demigod form.
