Cleric Warframe concept - "Odo"

Odo, the Void Cleric

High energy, medium health, medium armor, low shields

Passive: Faithful of the Void - Odo's sacrifices to the void via Pray provide him with Faithfulness charges, of which he can have up to 12. Each Faithfulness charge grants 50 armor and 1hp/s regeneration. Additionally, abilities that have consumed charges grant half the energy cost of a charge on kill.

1st Ability: Pray - Odo kneels, channeling energy to the Void in exchange for Faithfulness charges. 1 charge is granted per 25 energy channeled; this does not have to be in a single session. Pray scales inversely with Duration, consuming energy faster with higher percentage.

2nd Ability: Holy Hammer - Odo lashes out with his hammer in a wide arc, dealing Impact damage. Hitting an enemy with a hammer strike enables a combo; the second cast only costs half and deals double damage, while the third cast costs a quarter and is a triple damage AoE. If Odo has any Faithfulness charges, each strike consumes one in exchange for doubled damage.

3rd Ability: Channel Void - Odo unleashes a burst of void energy. Allies are healed, and enemies are blasted with pure Void damage. Requires one Faithfulness charge to cast, but can be charged up to an additional four charges for a linear increase in damage.

4th Ability: Faith Aegis - all allies within range are granted a temporary shield that absorbs 50% of incoming damage and converts it to an armor buff on expiration. Requires four Faithfulness charges to cast, but can be charged in increments of 4 charges for diminishing returns on the damage reduction (maxing at 87.5%).
