Mirri Elendis Companion Guide for ESO


With Update 30, in mid June of 2021, ZOS added a new ESO Companion System. These are NPCs that will travel alongside the player and will be a companion that can tank, dps or heal.

Mirri can help any player defeat more difficult enemies and especially newer players have an opportunity to pick up bigger challenges, without having to ask others.

Also, if the group is a player short, Mirri can replace a group member. Meaning if they want to go into a 4-player dungeon and they are only 3 people, someone can summon Mirri and the group will be full.

Mirri won’t be able to do complex mechanics, though, so she might not always be favored over other players.

It is also not possible to summon Mirri while in combat, but perfectly able to unsummon her while in combat.

She will also not be able to be summoned in PvP instances, in single player arenas or in housing instances.

Also, in instances where you can’t navigate to Mirri and talk to her, she will be briefly invisible, such as while swimming.

At this point in time you cannot romance Mirri.

Mirri - Rapport and Disapproval or Approval

The rapport shows the relationship status with Mirri. It can range from extreme dislike and contempt to viewing the player as their greatest ally and dearest friend. The player can decrease and increase the rapport via their in-game actions. Different actions have different cooldowns, so that rapport can not be positively or negatively influenced in rapid succession.

Mirri - How to get her

Where to find Mirri close to the Doombault Vulpinaz in BlackwoodMirri is found in the Doomvault Vulpinaz objective in north Blackwood. She seems to be an adventurer that has been answering a job posting that was seeking adventurers to help explore a new discovered ruin. Only after the expedition got underway the employers turned on her and her group of adventurers, among them her brother.

She now wants to free her brother and the others before something terrible might happen to them. She asks us for help and offers to pay us in return.

Mirri - How to access her

Players wanting to acquire Mirri need the Blackwood Chapter, so that they can unlock her through completing associated quests in the Blackwood zone. After this she will start following the player and will be available by either choosing from the Collections, or by quickslotting her via the Quickslot inventory. Her collectible can be found in the “Allies” section.

It is not possible to have multiple Allies or Assistants active at the same time, such as a banker and a companion.
Collectibles menu where you can find in your collections the allies section with the companions and which you have collected so far
The companion menu of Mirri with an Overview and the Equipment and Rapport
Mirri's Menu can be accessed when talking to her.
The first page is an overview, showing the Combat Level of Mirri, as well as whether she is wearing an outfit and if, which.

The next item is Mirri's ability bar. She has 5 skills plus an Ultimate ability, which unlock the higher her Combat Level is. She has a priority of when to use which skill, so from the left to the right the priority becomes less. Next would be the Rapport. This shows what Mirri thinks about the player and whether she is more likely to engage friendly with the player, or not.

The player can also access her equipment from here, which they have to carry in their inventory in order to have her equip it.

Mirri - Rewards

Mirri has two associated personal side quests which will become available to the player once a sufficient rapport has been established. Completing the second companion quest will unlock a houseguest collectible of her, allowing her to be placed and utilized similarly to other houseguest collectibles.

Keepsake of Mirri called Ancient Anticipations Idol

Completing any of Mirri's side quests will result in a large rapport boost.

By completing meta-achievements associated with her, the player can unlock a keepsake collectible for Mirri which provides the benefits of the non-combat perk even while she isn't active.
This collectible is located under the Upgrades section of the Collections menu.

Mirri - Skills

In order to engage with Mirri, talking to her will initiate a conversation and you can select the Companion Menu option.
This will bring up the Companion interface. It is the second icon from the top right.

Companion weapon skills with ability priority

All available skill lines are listed here, with the three Class skill lines at first, followed by the Weapon skill lines. The player has to equip a weapon first before it can unlock. The Class Skill lines increase with the combat level of Mirri.

Same goes to the Armor skill line. 3 items of the same weight have to be equipped in order for the skill line to be equipped.

Weapon and Armor skill lines all increase through combat experience based on what the player carries.

The Guild skill lines are almost identical to the player Guild skill lines, only that there's only Fighters Guild, Mages Guild and Undaunted available so far. They increase through completing specific solo daily quests associated with the guild, for the active companion.

To find out how to find and complete the guild daily quests to level up Mirri's guild skill lines, check out this guide to guild daily quests.

There's also only 1 Racial trait available which will be available from the beginning and won't need to be unlocked.

Mirri does not have Champion Points.

Mirri - Equipment

In order to engage with Mirri, talking to her will initiate a conversation and you can select the Companion Menu option.

On the first page on the left side the Equipment is available. A player has to carry the equipment they want her to wear in their inventory, otherwise it will not be possible to equip it.

Mirri has the same equipment slots as the player, except for only being able to slot one weapon set, as she only has one ability bar. The quality of the equipment ranges from normal to epic, with being either traitless or having specific traits. A player will not be able to craft Mirri gear, but will have to find the equipment. Mirri's equipment does not include level, cannot be enchanted, does not require repairs and does not include an inherent style appearance, but instead inherits Mirri's style.

White companion equipment can be purchased from Weaponsmith, Woodworker, Armorer, Leatherworker, and Tailor merchants throughout the world, particularly from bosses.
This equipment can be traded so it can be bought and sold on the market.

Companion's Robe equipment aggressiv

The traits are as follows:
  • Aggressive - Increases Mirri's damage output (per equipped piece).
  • Augmented - Increases the duration of all her buffs and debuffs (per equipped piece).
  • Bolstered - Reduces the Damage Taken by Mirri (per equipped piece).
  • Focused - Increases the Critical Strike Rating of Mirri (per equipped piece).
  • Prolific- Increases the Ultimate regeneration of Mirri (per equipped piece).
  • Quickened- Reduces the Ability cooldown of Mirri (per equipped piece).
  • Shattering - Increases the Penetration of Mirri (per equipped piece).
  • Soothing - Increases the Healing Done of Mirri (per equipped piece).
  • Vigorous - Increases the Maximum Health of Mirri (per equipped piece).

Mirri - Customization

In order to engage with Mirri, talking to her will initiate a conversation and you can select the Companion Menu option.

From here you can choose two different customizations. At the very first character sheet on the right side, underneath the Combat Level, is the Outfit. Here the player can choose between No Outfit and Companion Outfit.
If the player decides to go with No Outfit, the current equipment that Mirri is wearing will be displayed. If a player wants to have a costume that they own worn by Mirri, they have to choose the Collectibles icon on the top right. Here a player can also set the mount that Mirri is supposed to ride.

In order to have their own customized Outfit displayed, the player needs to go to an Outfit Station that is not in a player's house because Mirri needs to be active at the time of customization.

In the Outfit Station menu, the player can choose between themselves and Mirri. From here it works the same as with a player Outfit. You can also choose colors for both the Outfit or a Costume at this station.

The head armor will be hidden at all times and will not be displayed regardless of equipment or cosmetic override settings.

Depending on gender, race or other restrictions, some of the player's cosmetics might also not be usable by the companion.

Players can't use polymorphs, personalities, skins, hats, hair or tattoos on companions.
