Monster Spawn Tables by Level

1-2	1	0	1

10-19	2	3	3

Special Spawn Replacements

At higher levels, danger level 3 monsters have a small chance (1.2%) to be replaced by monster swarms:

• 3x Animals, 4x Apex Predators, 6x Bangers, 3x Bellas, 3x Birthday Boys, 3x Bowties, 3x Chefs, 3x Elsas, 2x Gambits, 10x Gnomes, 3x Headgrabs, 2x Heart Huggers, 2x Hiddens, 3x Mentalists, 2x Ooglies, 3x Peepers, 3x Rugrats, 4x Shadow Children, 4x Spewers, 4x Ticks, 3x Upscreams

Monster Economics

Each monster can drop up to 3 Enemy Valuables per level (except Gnome, Banger, and non-full-HP Tick). After 3 drops, they stop dropping orbs.

Value by Monster Level:

• Danger 1: Small orb ($2K-$3K)
• Danger 2: Medium orb ($3.5K-$4.5K)
• Danger 3: Large orb ($5.5K-$7.5K)

Optimal Monster Farming:

• Early levels (1-5): Kill everything for easy orbs
• Mid levels (6-10): Selective killing—focus on danger 2 for better value
• Late levels (11+): Avoid combat unless necessary; respawn timers are too short

Understanding every monster's behavior is the foundation of R.E.P.O. mastery. Study this guide, learn the patterns, and the monsters become predictable obstacles rather than terrifying threats.
