Boss guide: keys, the four bosses, Typhon and the Ubers

The road from your first boss key to Typhon and the Ubers. Every fight is solo, has no level requirement and is open from day 1. Move names are on each tile in /boss.

The ladder

Getting keys

• Expedition end bosses are the main source. Each key is a random one of the four, and higher area levels pay more. See the PvE guide.
• /tribute shop: 15,000 Tribute a key. Tribute needs a Siege base (level 30).
• Mystery Boss Summoning Keys from the free Season Pass track. The paid track gives boss keys too.
• The Boss Keys Found gang upgrade adds up to 20% to what Expedition bosses drop.

Before your first fight

• Try one as soon as you hold a key. If you die, the portal reopens for you alone for 60 seconds: walk back in for a free practice run of the same fight. It pays nothing.
• Wear a full set of your best armour. Full iron blocks 77% of boss hits, full diamond 84%.
• Spend your Hunter tree points. You can't respec or switch presets inside a boss arena.

You keep your inventory and levels if you die. The key is spent. A fight times out after 20 minutes. Shared rules are on Boss Fight Mechanics.

Which boss

• Kill each of the four once before you farm one. Each kill drops one Etna Fragment of that boss, and Typhon takes one of each. None of the four is the easy one.
• Finish the First Expedition step of Beyond the Mines first. Boss kills from before it opens don't count for the next quest line.

Ten kills a day

• Your first 10 boss kills each day roll the boss's pool twice. Bonus drops are not doubled. Typhon counts toward the ten. Ubers don't.
• Spread your keys across days. Ten a day for three days pays more than thirty in one sitting. Resets at 11 AM Pacific.
• Boss Mastery: at 25, 100, 250, 500 and 1,000 kills of one boss you gain 2% increased damage and 1% less damage taken against it per step. Works on the four and Typhon, not Ubers.

Drops are on Boss Loot.

Typhon

Click one Etna Fragment from each of the four bosses into his seal, then Summon.

• There is no practice run and a lost fight does not return the fragments. Go in with your best gear.
• You keep your inventory if you die.
• The paid Season Pass track gives a Typhon summon at levels 22 and 44.

Ubers

1. Farm Ichor from fissures at area level 100 and up. /tribute shop sells 16 Ichor for 3,000 Tribute.
2. Buy a Sacred Map for 100 Ichor from the Ichor Broker or /sacredmaps. Pick the bloodline of the Uber you want.
3. Close every fissure, then kill the Avatar. The map runs at area level 103 and the Avatar is one chance: die and the map is gone.
4. Each Avatar pays 2 fragments. Combine 4 at that Uber's altar. Plan on two Sacred Maps per summon.

Ubers get the free practice run after a death. They don't get the daily bonus or Boss Mastery. The paid pass gives a Mystery Uber Boss Key at level 49.

Talos

Talos runs the four bosses for you.

• $1,000,000 once, plus Ancient Energy on top of the key every run (from 250,000 for Lamia).
• Needs hand kills first: 50 Lamia or Echidna, 100 Thanatos, 200 Hephaestus.
• A run can fail and still use the key and energy. It pays no Etna Fragment and no bonus drops, and never runs Typhon or Ubers.

Unlock it when you have more keys than time. Until then your ten doubled kills a day are worth more by hand.
