New Bosses & Loot

Auroracle, The Venerated, and Ceiros, The Shattered Sentinel, join Terraria’s roster of bosses upon installing the Starlight River mod.

Auroracle, The Venerated

A pre-Hardmode boss found in the deep layer of the Ice biome. To find its arena, search for a room that gives you an introduction to the mechanics involved in the boss fight. Then, descend the elevator to reach the boss’ location, called the Ancient Cathedral. Upon reaching the bottom, throw the Suspicious Looking Offering item into the water, triggering the boss fight. Good mobility is vital to win this fight. Plus, you must have blocks, as you need to place them when Auroracle fires its laser from the water. Winning the boss fight gives you a chance to receive the following items:

• Aurora Crown (Summon Sentry)
• Aurora Bell (Summon Sentry)
• Tentalance (Melee Weapon)
• Octogun (Ranged Weapon)
• Overflowing Urn (Magic Weapon)
• Tentacle Hook (Grappling Hook)
• Squid Fins (Accessory)
• Mantis Technique (Accessory)
• Tiger Technique (Accessory)
• Snake Technique (Accessory)

Ceiros, The Shattered Sentinel

Reaching Ceiros requires you to go through the new Vitric Desert biome. Here, you must find and defeat the mini-boss Glassweaver, Worker of the Anvil. Defeating this enemy gives you the key to enter the biome’s dungeon area. Open the locked door with the key, and enter the dungeon. Solve different puzzles until you can get the Cloud Burst ability. Use it to perform a dash that can also destroy special crystal blocks. Aim for the dungeon’s exit, but Ceiros will eventually appear and block your progress. This unique boss fight requires you to use your newly acquired Cloud Burst ability to destroy the crystals that spawn in the arena. Destroying these crystals leaves Ceiros vulnerable, allowing you to damage it as much as possible before the cycle begins anew. Defeating Ceiros will give you a chance to receive the following items as rewards from the fight:

• Refractive Blade (Melee Weapon)
• Recursive Focus (Summoner Weapon)
• Facet & Lattice (Melee Weapon)
• Needler (Ranged Weapon)
• Coalescence (Magic Weapon)
• Magmite Vacpack (Summoner Weapon)
