Adrenaline (mechanic, UDC)

Beetrix, for example, becomes invincible under the affects of Adrenaline, Rune gains infinite Mana and can spam spells for a short amount of time, Ether becomes camouflaged and doubles her movement speed, etc.
Adrenaline Effects
Character name	Triggered by: 	Adrenaline Capacity	Effects 	Duration 	Notes
Rune 	Taking damage with Mana Hearts 	150 	Lowers spell cooldown and provides infinite Mana. 	10 seconds 	
Sten 	Dealing damage while holding his breath	400 	All rifles can be rapid-fired (in hipfire) and have significantly increased accuracy.
Sten's Auto-Dagger can be thrown and deals up to 80 damage before falling to the ground.
Sten is unable to hold his breath or aim down sights.
Time is slowed down while Adrenaline is active.	9 shots 	Adrenaline is only consumed on successful hits.
Beetrix 	Dealing damage 	780 	Beetrix deals 70% less damage, but is completely invincible and gains +25% movement speed.
He can also dash into enemies by double-tapping in any direction.
Dashing into enemies causes them to explode, touching non-boss enemies crystalizes them in amethyst.	10-22 seconds	"Glass Structure (Lavender)" by DM Dokuro plays while Beetrix is invincible.
Beetrix's icon switches to him with an enraged expression with amethyst crystals replacing his eyes.
Coatyl 	Taking Bane damage 	6 (70 while active)	Coatyl becomes a wraith-like being with numerous skulls following him. He can spray a constant stream of BlackFire and cast spells at the cost of 1-2 Mana each. He regains Mana by using his fire-breathing, although this rapidly drains his Adrenaline meter.	40 seconds 	Coatyl's Adrenaline form resembles Samael (a fanmade Binding of Isaac character) using his active item, Malkah Mot.
Ether 	Dealing damage with her katana 	235 	Ether becomes a black shade with doubled movement speed and enters a "bullet time" state. Double-tapping in any direction causes her to dodge in said direction, and she can only use silenced weapons or her katana. Dodging into an enemy causes her to swing her katana at them, dealing 200 damage but depleting her Adrenaline by 150.
Adrenaline slowly drains over time, 10 Adrenaline is consumed with each dodge.	30 seconds 	
Peyero 	Dealing fire damage and getting burnt 	270 	Peyero's body becomes engulfed in Brimstone flames. As a result, the following effects are provided:
* A temporary Infernal Heart,
* Doubled damage and increased movement speed,
* A trail of damaging fire,
* Passive Mana regeneration,
* 80% increased range for all weapons,
* The ability to ram into enemies, deal contact damage after gaining enough speed,
* And the ability to exhale wide streams of fire by holding the Adrenaline key.	20 seconds 	If Peyero is slow enough, he loses the ability to ram into enemies.
Peyero's fire breath follows the player's cursor. Its damage cannot be changed, however.
