Dodge perpendicular to its path. Cannot be knocked back. Long range items are safest.
Needs Beads of Fealty at Obelisk. Killing on Monsoon = Mastery skin for your survivor. All 4 variants share the same attacks but different item loadouts.
Understanding these systems will change how you approach every teleporter event.
How Bosses Spawn
Activate the Teleporter to begin the event. One boss spawns immediately, chosen from the stage-specific pool. The boss must die before the Teleporter finishes charging. After roughly 15 minutes into a run, bosses also begin spawning in the open world as regular enemies.
Shrine of the Mountain
Doubles the credits available to the boss director per activation - meaning harder or more numerous bosses. In return, the Teleporter drops 100% more items. Each extra item also has a chance to be a boss item. Stack Shrines early when boss credits are low and the risk-to-reward ratio is in your favor.
Boss Scaling
Every boss gains HP and damage per level, which increases continuously with time. Playing slowly is a direct threat. After looping (clearing Stage 5 and restarting), bosses are significantly stronger and gain additional attack patterns at lower HP thresholds. Monsoon accelerates this rate faster than Drizzle.
Adaptive Armor
Mithrix, Voidling, and Solus Wing all have Adaptive Armor. Each hit grants temporary armor equal to 30 per 1% of max HP dealt, capping at 400 and decaying at 40 per second. Sustained consistent fire beats burst DPS every time against these bosses. Symbiotic Scorpion permanently reduces armor per hit.
Boss Items
Each boss has a small chance to drop its unique yellow boss item when it is the Teleporter Boss. Shrine of the Mountain increases the number of items dropped, giving more rolls. Trophy Hunter's Tricorn (SotV DLC) instantly kills any boss and guarantees its item. Yellow Item Scrap can be used in Overgrown 3D Printers.
Monster Logs
Any boss has a 3% chance to drop its Monster Log if you have not yet collected it. This chance is affected by 57 Leaf Clover (increases chance) and Purity (decreases chance). Voidling only drops its log during the final phase. Twisted Scavengers have no logbook entry.
Which Boss Spawns on Which Stage
Teleporter bosses are drawn from a stage-specific pool, not randomly from all bosses. The table below shows the possible pool per stage group. On higher loops and Monsoon difficulty, more powerful variants and multiple simultaneous bosses become common.

Hardest Bosses Ranked
Based on mechanical complexity, damage potential, and what happens when things go wrong. Difficulty increases significantly on Monsoon and in post-loop runs.
1Solus Wing
1,000 armor, 4 attack phases, Heat Vents, laser grids - highest skill demand of any boss
2Voidling
Nullifier Black Hole ignores all invulnerability. Phase 3 forces close range. 3 platforming gauntlets.
3Mithrix
Steals all your items in Phase 3. Adaptive armor. 4 phases. The definitive skill check.
4Solus Heart
Instant-kill laser pillars. Collapsing cube arena. The accept/reject choice ends or continues your run.
5Wandering Vagrant
Genesis Supernova is one of the most lethal single attacks from any teleporter boss on Monsoon.
6Imp Overlord
Decimate has a deceivingly large hitbox. Teleport cooldown means you cannot kite it.
7Twisted Scavenger
Wipwip's Behemoth explosions and Guragura's 84% bleed chance per pellet are both capable of one-shots.
8Grovetender
Only dangerous if Lemurians aren't killed fast. Scorched Shotgun near slopes can send you flying.
All Boss Items
Each boss has a small chance to drop its yellow boss item when it serves as the Teleporter Boss. Shrine of the Mountain gives more item drop rolls. Trophy Hunter's Tricorn (SotV DLC) guarantees the boss item on kill and is consumed on use.
