Veena - Helminths daughter (Infested)

[(PSN)damianp1000]

Backstory:
Abandoned Mycona Colony hides one more secret - the appearance of Sentients in Origin system awakened the sleeping Helminth. Instead of starting to consume materials, Helminth spat out the Warframe - daughter of Helminth.

Illustrative image, generated by AI.

Passive - Warframe can adapt to the conditions on the battlefield, hold down the skill button to select one of the 4 modes (e.g. Lavos): Speed (Triuna Runners), Armor (Triuna Maggots), Fighter (Triuna Tendril Drone), Mind (Triuna Crawler). 
Note that Triuna is used here as a prefix to indicate a separate species, only related to this warframe.

For example:

• Speed adds X% movement speed and X% bullet jump - the arms and legs cover with a infestation
• Armor adds X% armor and X% health - infested armor appears on the face and arms
• Fighter adds X% attack speed and X% critical damage - infested blades (melee) grow out of her wrists
• Mind adds X% ability strength and X% ability range - the growths on the head elongate and begin to throb

Abilities:
1 - Contagion - puts tumor on target enemy - enemy is staggered for X seconds. If killed before infestation ends - tumor spreads to nearby enemies within X meters until the remaining duration time runs out.
Subsumable to Helminth.

2 - Infested Overload - channeled ability - aura doubles passive bonuses and spreads X% of them to allies within X meters but drains X% health for each second

3 - Spawn - summon infested of the selected mode (e.g. Speed summons Triuna Runners). Spawned Infested prioritize enemies with tumors (1st ability). If there are no enemies nearby they follow the Warframe.

• Triuna Runners - will charge the nearest enemy (or affected with tumors) and detonate themselves leaving a toxin cloud
• Triuna Maggots - they climb onto the nearest enemy and set them on fire
• Triuna Tendril Drones - shoot homing projectiles applying cold proc and then latch onto enemies
• Triuna Crawlers - electrocutes nearby enemies (similar to Arc Mine) and also have raised threat level, causing enemies to prioritize attacking them

Ability for sure needs cooldown and fixed number of spawns.

4 - Sacrifice - absorb all spawned infested (3rd ability) - emit a radial pulse that deals (X * number of absorbed infested) damage to enemies and inflicts proc status depending on the type and amount of Triuna Infested consumed, for example:
if two Triuna Maggots (fire) were absorbed - two fire procs
if Triuna Runner (toxin) and Triuna Maggot (fire) were absorbed - one toxin and one fire proc

Melee weapon:
Infested blades - melee working similar to Garuda talons: not using energy, have separate slot in load-out,  looks like claws on Helminth's chair and slipping out of her wrists while Fighter passive is activated.

What do you think? Any idea how to improve/balance it?
