Mini World Bosses
Mini world bosses are a set of 12 world bosses introduced alongside the larger world bosses during the Lost Empire expansion. They all have 184,903 HP and can be soloed by most classes at level 9x. Hunting mini world bosses is often extremely competitive as they tend to be killed very quickly after they spawn. The best chance to find one is immediately after a server maintenance. Try to be one of the first ones to log back onto the server and you may get lucky.
Mini world bosses drop mirage celestone, scarlet fruit, level 5 / 6 apothecary items (including Irongaurd Powders), and Chrono pages (1% of the time).
