Bosses are significantly stronger enemies that can be spawned manually.
There are 29 boss fights in Advent of Ascension (note: some boss fights consist of more than one entity).
In this mod, fighting all bosses is an optional task; the player does not need to battle any of them in order to progress through the mod. However, a couple bosses are required to be spawned in to progress to certain dimensions (though the player does not need to fight them afterwards).
Most bosses have a boss bar that appears on the top of the screen when the boss is in the general vicinity of the player.
Bosses in the mod have to be spawned in order to be fought. In most cases, this either involves using (defaults to right-click) a special item on a specific boss altar, or by tossing an item on the ground and waiting a few seconds for the boss to spawn (a few bosses are exceptions to this rule).
When the player defeats a boss added by the mod, said boss can drop a wide range of items. All bosses will drop a Trophy of themselves when defeated (some bosses have a variation of this). Most bosses will have a chance to drop a few, fully completed weapons, as well as various miscellaneous items such as Magic Repair Dust and Gold Coins. Most bosses can also drop items from a dimension's world table. The player is not guaranteed to get all drops from most bosses at once.
Due to their optional nature, the bosses can usually be fought in any order the player wants, with few exceptions.
