The ESO Companions system is a new addition to ESO (Elder Scrolls Online) in 2021 with “Blackwood”. The ESO Companions system allows you to have non-player characters called companions. Companions can aid a player in their adventures, follow them into dungeons and perform various roles as they assist in combat.
The more time a player spends with the companions and gets to know them better, their effectiveness will increase and their standing towards the player will either increase or decrease. The more they like the player, the more willingly they will become to share personal information and award the player with personal quests. They can also wear specific gear and can be customized in many ways, including their abilities, mounts, costumes, outfits and more.
They also come with specific perks. The moment you call them, each companion will give you a benefit to your surroundings or items. The more you get to know your companion, they will decide to give you a token of their friendship, which means that you will be able to use their perk even if they are not active.
