Anomalies and pet artifacts
About 1.7% of dropped charts are cracked: an Anomaly, shown in purple. At your 50th kill, the map's boss walks out with special powers, and beating it pays cores and pet artifacts.

How it works
It plays like a chart until your 50th kill. Then the map's boss walks out, anomalous, with one to three powers (+35% health each). A map without a boss borrows one, brought down to its level.
What it pays
Everyone in the run gets 
Anomaly cores (one per power), a pet artifact (now and then the boss's own unique), the boss's drops again for each power, a rolled piece, one of 
the rare tools, and a chart a tier up. Cores open the Compass's keystones and can wipe it.
The powers
| Power | Does | Beat it with |
|---|---|---|
| Enraging | +10% damage every 30 s it stays up | damage; a fast clear |
| Leeching | heals a quarter of the damage it deals | Thorns; the Buckler; damage |
| Echoing | each hit repeats a second later for half | damage taken; the Buckler; Big Heart |
| Volatile | every 8 s it scorches everyone within 2 tiles for 6% of their health | fire resistance; keep your distance |
| Summoner | at 75, 50 and 25% it calls four of the map's monsters | a party; Lifeline |
| Splitting | at half health it splits in two, each with half of what's left | a party; Giant Killer |
| Blinking | every 10 s it steps to whoever is furthest away | a party that stands together |
| Pickpocket | each hit on you takes a meal, drink or potion | kill it fast |
Pet artifacts
Small rolled items for your pet: 
a Collar works in a run (a heal, the first hit softened, a share of every hit taken), 
a Tag lifts your pet's own bonus inside its caps, and 
a Bell helps with charts and Anomalies.
- Walk a pet: it opens one slot at pet level 10, two at 30, three at 50.
- Open the Workbench (O), go to the Artifacts tab, and click one in your bag to fit it.
- They're fitted on you, so they work through whichever pet is at your heel.
