Alathra:Bosses
Bosses are enemy mobs with greatly increased health and stronger, special attacks. Bosses can be encountered randomly in the world through summoning entities, or need to be spawned in by players using specific structures. Some valuable items can only be obtained as boss loot.
Regional bosses
Building a Regional Altar enables players to summon bosses specific to their area. These bosses drop items referred to as regional resources, which can be exchanged at Spawn for various items referred to as regionals. There are 6 regional bosses to match 6 regional resources:
•  Alexandrite |
•  Amber
|
•  Gemcorn |
•  Ironwood
|
•  Rainbow Eucalyptus |
•  Seaglass
|
Every regional boss can be summoned with the same altar, by right clicking the center piece of the altar (the gold block) with an emerald.
