Clean Up on Isle Siren Rares Locations & Achievement Guide

With the Siren Isles now open for business you can work on the Clean Up on Isle Siren achievement! This guide will offer information on when you should expect these rares to be up and where to find them. It should be noted that all of these can be found during the non-storm phase of the map, but not all will spawn each week as some are tied to weekly invasion events.

Thankfully, Blizzard was super helpful and released an official map of The Siren Isles with markers for where the rares spawn in this tweet!

Major Excavation Rare Spawns

There are three rares that will only spawn when the contributions to the relevant major excavation are at 100% from the Siren Isle Command Map in the main town of Flotsam Shoal. This is a collaborative effort, so make sure to check the map often to see if these are available even if you don’t have the Flame-Blessed Iron currency to get it to 100% yourself! Once these are filled there will be a timer where through some sort of big-kaboom the entrance will open and the rare will be able to be fought. It’s recommended to bring a group for these as soloing them will prove difficult.

Invasion Rare Spawns

There is a rotating invasion event that changes weekly between Vrykul, Naga, and Pirates that have a couple of rare mobs that will only spawn when the relevant invasion is up.

Vrykul Week Rare Spawns

Naga Week Rare Spawns

Pirate Week Rare Spawns

Randomly Spawning Rares

These will always have a chance of spawning and will often have a zone-wide ominous message specific to each of them that displays in the chat right as they spawn. Some of these have quite the long spawn timer, though, so you may want to search for groups where they’re confirmed up or try to find unpopulated layers to snag them before they’re killed.

General Tips For the Clean Up on Isle Siren Achievement

• A lot of these, barring notable exceptions, have a respawn timer of 10-15 minutes. If you get there too late and stick around you’ll likely get another shot at the rare.
• There have been reports of glitches and inconsistencies in tagging these rare mobs when there are lots of people gunning for them. They grey out after a certain amount of people tag them, which is likely intended, but the amount of people can be much lower than it’s supposed to be. If you see them still taggable within range make sure to spam those ranged abilities!
• The Forgotten Vault is the tomb-like area you were first spawned into during the introduction to Siren Isles. You can get back there by going into the cave with the “Singing Tablet” in the Sacred Hollow and clicking a dialogue option. There are a few rares that spawn exclusively within this vault.
• All of these spawn in the non-storm phase of the Siren Isle.
