How to unlock the Arun Boss achievement in TERA - Definitive Guide
As a suggestion, you can change the channel within the server you are in to increase the probability of finding the bosses without waiting for them to respawn.
Here is the list of each one and the possible locations.
South Arun (11 bosses)
Arakia, Ovolith, (Around 1 hour spawn)
Lanok, Giant, (Around 1 hour spawn)
Barraq, Kumas, (Around 2 hours spawn)
Atrocitas, Firmbrilisk, (Around 4 hours spawn)
Deathglare, Basilisk, (Around 1 hour spawn)
Abraxis, Crab, (Around 1 hour spawn)
Tabruk, Vulcan, (Around 2 hours spawn)
Trunus, Lizard, (Around 1 hour spawn)
Solrachnus, Arachnen, (Around 6 hours spawn)
Divine Reaver, Vulcan, (Around 4 hours spawn)
Kanash, Crab, (Around 5 hours spawn)
This achievement requires that you kill 11 unique bosses on the world map. Their names, levels, spawn timers, and locations (linked by the name) are all located below. Many monsters have multiple spawn locations, so check each spot to see if it spawned and kill it if so. If it isn't there, you can switch channels ( then ) and check in that channel as well. If it is not available at all, move on to the next monster and come back after to check again. Once you kill all 11 bosses at least once, the achievement will unlock.
The three Level 68 bosses in the game will either require you to have very high-end gear, or a decently large group of people to defeat. Prior to an update, these bosses were all under Level 60 and could be done solo, but they are now designed for end-game players.
