Is Electrician a 0.1% unit?
A current creator title reports 0.1%, but the live in-game banner or an official rate table has not been captured. Treat the number as unconfirmed.
The public Roblox game page confirms that Into the Backrooms TD is a tower-defense game built around summoning rare towers, unlocking Backrooms levels, cooperative play, and leaderboards. It does not publish a complete unit roster, official role sheet, rarity table, unlock path, or stat block for Electrician. That boundary matters: a creator title can show that players are asking about a unit, but it cannot safely establish every number or mechanic.
Recent creator videos use Electrician-like wording and an Electric Man label, including an acquisition-focused title. Those titles show real player interest in how to get the unit. They do not prove that 0.1% is the current summon rate, that the aliases are interchangeable, or that every video used the canonical in-game name.
