Black warlock

Black warlocks are butterflies that can be captured in the Feldip Hunter area and the Farming Guild with a Hunter level of at least 45, requiring both a butterfly net and a butterfly jar.

Once caught, black warlocks can be released upon another player in a multicombat area to increase the other player's Strength level.

Capturing a black warlock is a task sometimes assigned by Sherlock during an elite clue scroll.
