Bosses

There are nine bosses and thirteen minibosses in 30XX. Each stage has its own miniboss and end boss - unlike 20XX, levels are not shared between bosses. Gauntlets also feature 4 different minibosses, each corresponding to a Resonant Armor Piece.

Minibosses
Minibosses appear partway into their resepective stage, must defeated to progress further in the stage, and generally provide a choice between three different items upon their defeat. The sole exception currently is Delta, who can appear randomly as an optional miniboss encounter in any stage and gives a set reward (shown before the fight) upon his defeat.

Gauntlet Minibosses
These minibosses are always fought at the end of a Gauntlet, and drop their corresponding piece of Resonant Armor upon their defeat.

Extra Minibosses
These minibosses can be randomly seen within any level, and will drop an augment upon their defeat.

Bosses
Bosses are strong enemies that appear at the end of a level, and must be defeated to proceed. Defeating a boss lets you take its power (with the exception of Kur) as well as a varying amount of Memoria depending on both the player's current Entropy Level and how much damage they took during the fight. Defeating any boss after Level 3 will also give you a choice between collecting the Power, a Power Aug or a Remnant, or nuts.
