Minibosses

Minibosses are Mobs that are not quite Bosses but are significantly tougher than their regular counterparts. Unlike bosses they don't have an extra large health bar nor a leaderboard for who did the most damage.

Slayer Minibosses
Slayer minibosses have a chance to spawn after the player kills the corresponding slayer mob during a slayer quest of or higher. It is also possible to spawn another miniboss directly after killing one.
