Ignition

DefectSkillRare
Another player Channels Plasma.
Exhaust.

You target another player and they Channel a Plasma orb, which gives Energy on its passive and more when Evoked. The base card exhausts; the upgrade removes that so you can hand out Plasma every time you draw it. It only appears in multiplayer runs.

When to take Ignition

Take it in co-op when a teammate is a Defect with slots to fill, since a free Plasma becomes an Energy engine for them. Upgrade it so the gift repeats every draw.
