Passive: "Blood Price"; Sangua utilises a special currency system, Blood Points, in the casting of all of her abilities. Corpses near her are drained of blood over the course of 3 seconds, giving her blood points. Any given corpse's blood point value is equivalent to 10% of its Base Health. If Sangua lacks blood points to cast an ability, she will instead sacrifice 10 HP per missing blood point in order to cast. Blood point costs are tied to efficiency the same way as Energy costs are.

First Ability: "Circle of Consumption"; 30 Energy + 25 BP; Sangua creates a large ritual circle with a 7/8/9/10 meter radius, which instantly consumes all corpses within, giving 125/150/175/200% of their blood point value to her, even at range. Any new corpses which enter during the 10/15/20/25 seconds it is active are similarly affected. Living enemies within the circle take 10/15/20/25% extra damage. Up to 1/2/3/4 circles can be created at any time.

Second Ability: "Transfusion"; 15 BP/sec, toggled; Sangua channels, healing all nearby allies for 1/1.5/2/2.5 HP per Blood Point spent. If all nearby allies are fully healed, Sangua instead applies this healing to herself until either allies become damaged (at which point it resumes healing them) or she has full health (at which point casting ends). If she must sacrifice her own HP to cast, the ability cannot self-heal and deactivates upon full healing of her allies. While this ability is active, Sangua is unable to move, attack, or cast other abilities.

Third Ability: "Hemoshell"; 75 BP; Sangua grants herself and one targeted ally a shell of congealed blood, granting 20/25/30/35% damage reduction. Furthermore, the ally's shell amplifies all of their positive ability effects by 5/8/11/15%. The shell has its own HP pool equivalent to 25/50/75/100 HP, which is affected only by the damage blocked by the DR.

Fourth Ability: "Hemocurse"; 150 BP base; Sangua performs a dark ritual, infecting up to 2/3/4/5 nearby enemies with a horrific curse. Affected enemies have their base health drained by 7 points per second for 5/8/11/15 seconds. Enemies killed while under this effect explode, dealing 30/40/50/60% of their pre-casting max HP as Impact damage in a 5/7/9/11 meter radius, and also only grant blood points based on their final base health. If every enemy affected by this dies, a large ritual circle with a radius of 5/7/9/11 meters appears on the ground, buffing included allies by increasing their maximum and current HP and Shields by 20 points per 35 base health successfully drained by the initial curse. Charging the cast increases the maximum targets by 1 every 3 seconds, but the cost doubles for every two additional targets (gameplay wise it would scale on a formula to prevent exploitation of odd numbers).
		-----
Aesthetically, Sangua's abilities would all create (hopefully unique) ritual circles that appear to be traced in blood on the ground (think something similar to the transmutation circles in Fullmetal Alchemist). Three of them - Transfusion, Hemoshell, and the initial part of Hemocurse - would be rather small, possibly scaling with ability range. The other two, from Circle of Consumption and the secondary part of Hemocurse, would be the area of effect and by necessity would have to scale.
