Blood Mother Vampire/minion Warframe concept

Blood Mother (vampire/minion Warframe)

Passive - Brood: Blood Mother is empowered by her brood of vampires; each one is worth 1 (Spawn), 3 (Fledgling), or 5 (Blooded) Brood Points. Every 5 Brood Points, up to 10, improves her abilities and statistics.
0-4: Fledgling (normal stats)
5-9: Blooded (improved armor and energy)
10+: Mistress (improved health and casting speed)

First Ability - Claw: Blood Mother lashes out with her claws, dealing light damage and inflicting a mild bleed proc.
Fledgling: Normal.
Blooded: Affects enemies in a cone.
Mistress: Affects enemies in an AoE.

Second Ability - Embrace: Blood Mother rushes to an enemy in a cloud of smoke, embracing them and draining their blood to heal herself. She is vulnerable during this, and taking 25+ damage will interrupt, but if she successfully drains at least 50% of their max health without killing them, they will become a Spawn. Draining them to death instead will grant an HP boost.
Fledgling: Normal.
Blooded: Gain a shadowy shield while draining that absorbs up to 200 damage before dissipating.
Mistress: Shield will absorb up to 500 damage and slowly regenerate if undamaged for a few seconds.

Special - Vampire Spawn: Spawn created by Embrace are similar to Manics, except they cannot turn invisible or spontaneously regenerate health. They will attack enemies in groups with claws, but will pounce isolated enemies and drain their blood to restore their own health, which can be interrupted similar to Embrace. If they successfully drain enough enemies, they will level up.
0-2: Spawn (light armor, medium health, drain ability)
3-4: Fledgling (slightly better armor/health, can use a weaker Claw)
5+: Blooded (much better armor/health, can use Blooded-level Claw, has a small chance to create a Spawn when draining an enemy)
Spawn have basic AI, prioritising targets that are alone and those inflicted with bleed procs. They also seek out higher ranking minions, forming a pack of 3 (2 Spawn + 1 higher) if possible. Fledglings will wait to accumulate a pack before going on the offensive, and will prioritise tougher enemies with Claw. Blooded will also wait to accumulate a pack, and prioritise tougher enemies with Claw, but they also attempt to create new Spawn above anything except survival.

Third Ability - For the Brood: The minion with the least drains turns to smoke and teleports to the marked location, then explodes violently. Nearby enemies take damage, and the closest 3 will become new Spawn if they die within 15 seconds.
Fledgling: Normal.
Blooded: Nearby allies are healed.
Mistress: Nearby minions receive a speed buff.

Fourth Ability - Blood Ties: Blood Mother channels, strengthening her Brood and buffing nearby allies. For the duration, Spawn gain the abilities (but not statistics or Brood Point value) of Fledglings, and all Brood members and nearby allies gain improved health and armor. However, every Brood Point lost while the ability is active damages Blood Mother, and if she drops to half of the value at casting she takes even more damage and the ability is interrupted.
Fledgling: Normal.
Blooded: Spawn and Fledglings have their abilities (but not stats or Brood Points) elevated to that of Blooded. Allies and Brood gain improved damage.
Mistress: Blooded gain the ability to cast For the Brood, but have a Brood-wide cooldown and will avoid it if it would kill a Blooded.

Augments
1st - Stunning Claw: Claw stuns closer enemies, opening them to finishers and special instant-drains by Brood.
2nd - Consume Defenses: Blood Mother and Brood drain enemy shields and armor with Embrace and drain, transferring a portion to themselves.
3rd - Nesting Brood: The chosen minion becomes a fragile nest, emitting Spawn periodically for a short duration. Only one nest is permitted at a time, and they are a priority target for enemies.
4th - Blood Revenge: No longer elevates Brood powers, but every Brood Point lost while active gives a stacking, decaying damage and speed buff to Blood Mother and remaining Brood, instead of damaging her. No new Brood Points can be acquired until the buff decays fully.
