Pressure Cooker

#Overview

Pressure Cooker is the evolution of Steam Vent: a much larger steam cloud that also heals Tibo. Every 0.3 seconds it deals 45 damage to every enemy within about 84 units of Tibo (a size of 44 times its base area of 1.9), and each enemy it hits restores 0.12 HP, up to 2 HP per pulse. A maxed Steam Vent pulses for 30 every 0.5 s in a radius of about 67.

You get it by opening a chest while Steam Vent is level 8 and you own Root Network at any level. See Evolutions and Chests.

#How it works

The damage pulse works exactly like Steam Vent's, on its own 0.3 s timer, so cooldown and amount bonuses still do nothing for it, while area and damage bonuses do (see Steam Vent).

The heal is counted per pulse: 0.12 HP for each enemy inside the cloud, capped at 2 HP.^[1] The cap is reached at 17 enemies, which works out to at most about 6.7 HP per second. The heal is added directly to Tibo's HP, up to max HP, and no stat modifies it.

Measured in the headless sim (tools/play.mjs, build 41 main-B2gf34bA.js, Standard, Normal, god mode, seeds s1, s2 and s3; the seeded starting weapon removed, the weapon given with give, spawning stopped after 4 s of play and the pests already on the field held at fixed spots with 10⁹ HP; Tibo standing still, facing right, with 8 pests in a line 20 to 90 units to his right): it pulsed every 0.3 s for 45 and hit every pest out to 80 units but not the one at 90. All three seeds gave the same figures.

#Tips

• The heal scales with how many pests are in the cloud, so Pressure Cooker heals most when you are surrounded and nothing when the area is clear. Root Network's regeneration (+0.25 HP per second per level) covers the quiet moments.
• Area bonuses grow both the damage zone and the number of enemies that count toward the heal.

#Stats

Values are the raw numbers from the game's definitions, before Tibo's global stat multipliers, difficulty and time scaling. In play, Tibo's base stats add +1 amount to every weapon except aura, cone, nuke and ring weapons, and make every duration ×1.25 (see Stats). Field names in code are the game's internal names. Attack descriptions such as “Melee slash” are this wiki's summary of the internal attack kind.

Evolutions have no level-ups in the game data; they use these fixed raw values.

#Behaviour parameters

Raw parameters of the attack (behavior), copied from the game definition. What they do in play is explained under How it works above.

#Obtaining

• Get Steam Vent to level 8 while owning Root Network (any level), then open a chest. See Evolutions.
