Kaiser Behemoth (Episode Prompto)

Kaiser Behemoth is an optional enemy the player can engage in Final Fantasy XV: Episode Prompto. Defeating it yields the achievement/trophy An Emperor Deposed. It is a white variant of the behemoth king enemy fought in the main game. It is on Lv.99 but the rest of its stats cannot be observed.

How to find
The quest for the beast is available after getting the snowmobile. The quest appears from 15:00 in the northwest part of the overworld, next to the lake near to a shelter. Its appearance is denoted by yellow marker; when the kaiser behemoth does not spawn, a smaller group of enemies appears instead. The player can skip time at the camp to the north until the kaiser behemoth appears.

Battle
The player controls Prompto. Aranea can assist as an undefeatable guest after the player completes "Moving Forward" and starts "Sins of Our Fathers," and thus it is recommended to wait fighting the enemy until she joins. Prompto can't level up in the episode.

Near the battlefield is a shelter with various weapons where the player can replenish their arsenal. There are also some healing items hidden in the nearby rocks.

Strategy
The best damage is done with crackshots, which are available when the behemoth becomes vulnerable. Aranea's Highwind technique is a good way to put it in the vulnerable state. Breaking it with the sniper rifle also works.

Etymology
Kaiser behemoth is named in parallel to the king behemoth, the version of the enemy fought in the main game.
