Monster Training

Monster Training is a relic introduced in v0.5.37 of the game and added to the main rotation during Early Access. It was originally named "Monster's Pact" and renamed to "Monster Training" in v0.5.41. The relic modifies gameplay by triggering an effect based on the player's current maximum health threshold, making it a strategic choice for runs that manage or exploit low max HP.

The relic's trigger frequency scales with low maximum health: having a lower max HP makes Monster Training activate more often. Any relics or effects that increase maximum health will raise the activation threshold and therefore reduce how frequently Monster Training triggers. For this reason, players who want to maximize the relic's benefit should avoid acquiring max-health boosts or health-increasing relics for the remainder of the run.

Practical considerations and play patterns:

• Prioritize builds that deliberately keep max HP low (through items, curses, or choices that reduce/maximize risk) if you intend to rely on Monster Training as a core synergy.
• Avoid picking up relics or powers that increase your maximum health after obtaining Monster Training; such increases directly diminish its effectiveness by changing the threshold that controls activation.
• If your deck or strategy depends on consistent activation of Monster Training, treat other health-related relics and bonuses as trade-offs rather than free upgrades.
• Because the relic's behavior is tied to max HP rather than current HP, temporary healing or damage does not alter its activation chance unless it changes the maximum value itself.

Monster Training is best used on runs that favor fragile, high-risk builds that can capitalize on frequent activations rather than tanky, high-HP playstyles that blunt its value.
