Thanatos

A skeletal warlord wreathed in cursed flame, Thanatos is a Hard fight — the second-toughest of the normal bosses, with only Hephaestus above him and the Uber bosses above them both. He fights in three phases, and the lower his health drops the faster and meaner he gets.

Summoning

• Key: Thanatos' Idol, forged from 64 Essence of Thanatos. That essence drops from high-tier hunts (T5–T6 shades and wraiths). See Hunt Tiers & Boss Essence. The Idol is also sold in the Boss Shop for 10,000 Hunter Points.
• Requirement: Community Fund tier III — one tier earlier than before, and the only gate there is. The old level and prestige requirements have been removed.
• Summon him at his altar and enter the portal with your party. The full ritual is covered in Summoning a Boss.
• His altar also takes Thanatos' Unpaid Toll, the separate Uber key that calls Uber Thanatos from Fund tier V.

The fight

Thanatos opens more of his kit the lower his health falls — flame that blooms across the floor, runes that arm and detonate, and tethers that bind the whole party while he turns untouchable. The shared rules — tethers, telegraphs, arena resets — are explained in Boss Fight Mechanics. Read his tells and the openings reveal themselves; that's all we'll spoil.

A couple of fair-play notes: he slowly regenerates if you leave him alone, can't be slowed, and can no longer be stun-locked by rapid fire. His abilities now bite through armour rather than being shredded down to a tickle, so the telegraphs are worth respecting even in endgame gear. In his final phase, deaths feed him — stay alive. If you do go down, you respawn at his altar.

Drops

All loot goes to the summoner. The table runs from common crafting fuel and consumables up through enchant orbs and boosters, the Wrath of Thanatos offhand line, and his signature trim — the Thanatos Trim, his rarest pull, with a chase jackpot on top. For how rare-drop announcements and pity work, see Boss Loot & Drop Announcements.

Killing him pays the summoner 4,000 Hunter Points. Chasing the trim? Track your odds on the RNG Meter.

Looking for a different challenge? Echidna is the gentler boss below him, Uber Thanatos the harder one above (the only source of The Everwrought), and the signature special items from each boss are worth comparing.
