Luck multipliers divide base odds, improving drop chances during events. A 20x event transforms a 1-in-1000 drop into 1-in-50.

During 20x Admin Abuse: Los Lucky Block EV is strongly positive. Best time to spend.

Without events: Most Lucky Blocks have negative EV for late-game players. Conveyor belt farming is better.

Cursed Secret: Only positive EV during 20x Luck events. Baseline 0.5% chance jumps to ~10% effective with 20x modifier.

Los Bombinitos — 39.75% (~1 in 2.5)

Los Tortus (Secret) — 5% (~1 in 20)

Secret Lucky Block — 0.5% for La Secret
