Not to be confused with Sharp Plug.
Extension Cord is an unlockable trinket added in The Binding of Isaac: Afterbirth † (Booster Pack #4).
Effects[ | ]
- Bolts of electricity arc between Isaac and his familiars, damaging any enemies between them.
- The bolts do 6 points of damage per strike.
- The bolts flow through each familiar in reverse order of acquisition, and reach Isaac last.
- A bolt arcs every 2 seconds with one familiar. 3 of them arc per second with two familiars. 7.5 per second with three or more familiars.
Notes[ | ]
- The Forgotten acts as a familiar while controlling The Soul, causing electricity to arc between them. The same applies for Tainted Forgotten and Tainted Soul.
- Does not affect temporary familiars or The Swarm’s gray flies.
- The bolts will damage destructible obstacles, such as TNT and Fire Places, as a normal tear would.
- If taken as Jacob and Esau, electricity will arc to familiars held by both characters, not just the familiars owned by the character holding it. It will also arc between Jacob and Esau, even if neither have any familiars.
- In co-op mode, electricity will arc to all of them, similar to Jacob and Esau. Their familiars will also be connected.
Interactions[ | ]
- Extension Cord: Holding two copies or a golden version of this trinket, or having Mom's Box has no effect.
