Bosses

Bosses are AI-controlled enemies that you summon at boss altars around the map and fight for boss materials, rare loot and Hunting XP. Boss hunting is run by the NPC Gareth, who also offers Curse Crafting, the Boss Catalogue and the Hunting Talent Tree.

Altars are personal: each player loads and summons their own boss, so several players can fight separate bosses at the same altar at the same time. Only the players in a fight can damage its boss, so other players cannot attack your boss unless they are in your party.

Killing bosses levels up your Hunting skill. Each Hunting level gives a Talent Point for the Hunting Talent Tree, and boss materials are spent at the Obelisk.

Fighting a boss

• You can only be in one boss fight at a time, and you cannot summon a boss within 5 seconds of being hit (unless The Pact is active). After anyone summons a boss at an altar, that altar is locked for everyone for 10 seconds.
• While you are fighting a boss you cannot hit other players and they cannot hit you. The exception is a boss with the Cthonic modifier.
• Each boss has a time limit (see Boss Types). If it runs out, or every player in the fight dies or leaves, the boss despawns.
• If you die or log out during a fight you are removed from it.
• Bosses cannot be damaged by arrows, and many special attacks make the boss immune while they run.
• Special attacks deal true damage that ignores armour, and every special attack that hits you is listed in chat with a VIEW RECAP button that breaks down the damage.
• Bosses reduce your healing. Every boss has a base 20% healing reduction while you fight it, and each special attack that hits you adds more for the rest of the fight (2.5% or 5% for most attacks; a Plasma Nuke that detonates adds 100%). Passives such as Rot and Hunter's Mark add their own reductions.
• You must deal at least 10 damage to a boss to get any rewards from it.

Spawner System

• Each map has 4 altars at fixed places, for example Temple, Farm, Forest and Beach on Yggdrasil, Winter, Spring, Summer and Autumn on Seasons, and City, Port, Forest and Farm on Castle.
• Right-click an altar to load a boss into it. The boss is chosen at random: 50% Uncommon, 30% Rare or 20% Epic, then an even pick between the two bosses of that rarity. Its attacks and modifiers are rolled when it is loaded. Open the altar again to see its health, passive, attacks, modifiers and rewards (attacks you have not discovered in the Catalogue yet show only their name), then click to summon it.
• Each altar has 4 charges per player. A summon uses one charge. Used charges return one at a time, 40 minutes each, and summoning again restarts that altar's timer. The altar hologram shows the time to the next charge. A Boss booster makes charges return faster, and the Time Warp talent takes time off every altar's timer whenever you kill a boss.
• Parties: only the party leader can load and summon a boss. Every party member online on the same server is pulled into the fight and uses a charge at that altar. If any member has no charges left at that altar, the party cannot summon there.
• Curses summon their boss instantly, even when the altar has no charges left. See Curses.
• Battle Boost Potions come in Uncommon, Rare and Epic and are used on a loaded altar whose boss has the same rarity. Each one gives you (the summoner) +100% rewards and rare drop chance for that fight, up to 3 per fight. A Super Battle Boost Potion gives 10x instead and cannot be combined with normal ones.

Curses

A Curse is an item that summons one specific boss. Curses are made at Gareth from Curse Orbs.

• Curse Meter: Gareth's Curse Meter fills as you kill bots (+1, at most once every 1.5 seconds) and bosses (+100, once you have repaired the Obelisk; Curse bosses do not count). When it reaches 1,000 it empties and gives you a random Curse Orb.
• Curse Crafting: trade one Curse Orb for the Curse of any boss of the orb's rarity. The Curse rolls its modifiers when it is made, with a higher modifier chance than an altar boss, and its name shows them.
• Right-click an altar while holding a Curse to load its boss, then summon it as normal. Only you, or your party if you are the leader, can fight a Curse boss. Each extra party member who deals at least 10 damage cuts everyone's rewards and rare drop chances from it by 20% (two extra members: 64%, and so on).
• Curse Meter upgrades raise your odds of better orbs:

Curse Meter level	To reach this level	Curse Orb odds
1	Starting level	70% Uncommon, 30% Rare
2	Prestige 10, 12 Rancid Flesh, 10 Dusty Bone	40% Uncommon, 60% Rare
3	Prestige 20, 16 Rancid Flesh, 12 Dusty Bone, 4 Silk	35% Uncommon, 60% Rare, 5% Epic
4	Prestige 30, 8 Silk, 8 Porkchop, 8 Delicious Fish	25% Uncommon, 60% Rare, 15% Epic
5	Prestige 40, 24 Porkchop, 16 Delicious Fish, 8 Iridescent Ingot	75% Rare, 25% Epic

• Material Transmutation (Hunting Level 40): swap 3 of a boss material for 2 of its partner (Rancid Flesh and Dusty Bone, Silk and Porkchop, Delicious Fish and Iridescent Ingot), or convert Curse Orbs: 1 Epic into 2 Uncommon, 2 Uncommon into 1 Rare, or 2 Rare into 1 Epic.

Boss Types

There are six bosses, two of each rarity. Every boss can appear at any Hunting level.

Boss	Rarity	Mob	Health	Base hit damage	Speed	Time limit	Passive	Guaranteed attack
Undead	Uncommon	Zombie	300	0.5❤	1.0x	3 min	Rot	Eviscerate
Rattler	Uncommon	Skeleton	300	0.5❤	1.0x	3 min	Hunter's Mark	Meteor Shower

Boss Passives

Boss	Passive	Effect
Undead	Rot	Being hit by its special attacks inflicts Rot for 3s (each hit adds 3s more), reducing your healing by 30%.
Rattler	Hunter's Mark	Each arrow that hits you adds a Hunter's Mark, reducing your healing by 5% per mark. Being hit by a special attack clears all marks and makes that attack deal +10% damage per mark.
Scarab	Swarm	Hitting the boss has a 15% chance to spawn a Grub. Grubs deal 0.5❤ per hit and inflict Poison (-7% healing per stack, 3s).
Mutation	Enhanced	All of its attacks are upgraded by +20%: wider, faster to activate and with more projectiles.
Weeny	Mitosis	Every time it gets off its Roomba it splits off another Weeny with the same health, so a fight can have up to 3 Weenies. The fight does not end until all Weenies are defeated.
Iron Giant	Superconductor	Tosses out a Pylon nearby every 6 seconds (up to 4 at once). Damage dealt to it builds energy; at 100% it discharges, chaining lightning between itself and every Pylon. Lightning deals 3❤ and inflicts stacking Shock, which makes your hits charge it faster.

Boss Attacks

Each attack has a trigger: a health threshold, a number of hits the boss takes, a number of hits it lands, or a timer. The altar menu shows the trigger under each attack. Damage values are for one hit.

Boss Modifiers

When a boss is loaded into an altar it can roll a modifier that changes its stats and adds a mechanic. The chance is 25% (30% for Epic bosses), plus 1% per Hunting level, up to 55%. Curses roll with a 25% higher chance. Celestial and Timetwisted are rarer than the others, and a Celestial boss always gets one extra modifier. The Challenger talent gives a further chance at an extra modifier.

Each modifier except Weak raises the boss's rewards: +10% Hunting XP and boss materials per modifier (+20% for Cthonic), and a little over twice that for XP and coins. Health and Speed multiply the boss's stats; the Damage multiplier applies to its normal hits. Swift also makes special attacks trigger more often. Each modifier also adds its own rare drop (see Modifier drops).

Modifier	Health	Damage	Speed	Effect
Weak	0.6x	0.75x	—	Always added below Hunting Level 7. Gives no reward bonus.
Blazing	1.2x	1.15x	1.15x	Most of its attacks set the area they hit on fire after a short delay (2❤/s) and inflict Ignite for 3s (0.5❤/s).
Frostbitten	1.1x	1.15x	1.15x	Most of its attacks leave ice where they hit. Standing on the ice deals about 2❤/s. Being hit or standing on the ice adds a Frostbite stack: -10% movement speed and +7% damage taken from its normal hits per stack. Stacks reset 4s after the last one.
Swift	—	1.15x	1.25x	Moves and attacks 25% faster, and its special attacks trigger 25% sooner. Its normal hits add Windblown; at 10 stacks you are knocked back a long way.
Solar	1.25x	1.5x	—	Builds Solar Energy over time. At 100 it casts a Solar Flare in a 10-block radius. Move out of the way or die.
Blessed	1.5x	1.5x	1.3x	All of its attacks are Enhanced by +0.25x.
Stormforged	1.2x	1.25x	1.15x	Constantly summons Lightning Bolts around itself, dealing 3❤.
Infested	1.15x	1.1x	1.3x	Hitting it has a 15% chance to spawn a Grub (0.5❤ per hit, inflicts Poison).
Protected	1.2x	—	—	At 66% and 33% health it spawns a Protection Glyph. The boss cannot be damaged until the glyph is destroyed.
Celestial	1.15x	1.25x	1.3x	+1 modifier. Meteors rain over the arena, and most of its attacks inflict Ruin: +2% damage taken from its normal hits, -2% damage dealt, -2% movement speed and -2% healing per stack until the fight ends.
Timetwisted	1.1x	1.25x	—	All of its attacks are Enhanced by +0.2x, and it has a 30% chance to instantly recast an attack when it finishes.

Exclusive modifiers

• Coins and XP that scale with your prestige and the boss's rarity.
• Starless Ash, the universal boss currency, and the boss's own material.
• A roll on the boss's rare drop table, plus its modifiers' drops.

Rewards are raised by modifiers, Battle Boost Potions and the Bounty Hunting talent, and the player who started a Boss booster gets extra rewards while it runs. Your first 3 boss kills each day give 1.5x rewards.

Catalogue

The Boss Catalogue, opened from Gareth, records everything you have discovered across 4 categories: Bosses, Attacks, Modifiers and Loot. A boss, its attacks and its modifiers are recorded when you get rewards from killing it, and loot is recorded when it drops for you. The catalogue shows your overall discovery progress.
