Encounter details

This section is a list of specific combat encounters where The Emperor gets added into the initiative, and any specific differences about how The Emperor can behave in each combat encounter.

Astral Plane

This encounter is triggered by the quest Help Your Protector during Act Three.

• Even if friendly, the player cannot control his actions like a companion or summon.
• When the Emperor takes enough damage, they will use at least one Potion of Superior Healing. Up to 2 of these potions are available but using them here means the Emperor will not have them during later encounters.

NOTE:

• If The Emperor's hit points reach 0, the combat encounter immediately ends and a cutscene triggers. This results in a "Game Over" screen.

The Upper City

When it is finally time to Confront the Elder Brain, the Emperor can proceed as the player's ally during this final mixture of open-world and combat gameplay. The Emperor will be attached to one character like a summon for the duration of this battle.

• When The Emperor's hit points reach 0, they will become "downed" like any other controllable ally, and will make death saving throws.

Atop the Netherbrain

Ally

• The Emperor can be downed, and can die, but revivify and resurrection methods are allowed. On death then resurrection, for some reason, any unused potions of angelic reprieve will be dropped on the ground.^{[Needs Verification]}
• The Emperor is capable of casting spells off of some, but not all scrolls, if players open up the group inventory screen while the Emperor is actively selected, and right-mouse-clicks on the scroll item (PC Platforms only). The criteria allowing or disallowing the use of a scroll is unclear.

Enemy

• As an enemy, the Emperor will start combat with the  Volatile Shield condition.
