Luck is one of the most confusing stats in Mewgenics. The in-game tooltip only says it affects crit chance and randomness, but it doesn’t explain how the math works. Once you understand the system behind it, you can see why luck can heavily change your runs, especially when it comes to chance-based events. This guide breaks down how luck works, how positive and negative values affect your odds, and what it likely influences outside of combat. Also check out our Mewgenics Guide for new players!
How the Luck Formula Works
In Mewgenics, 5 luck is considered neutral. At this value, your rolls behave normally with no bonus or penalty. Each point of luck above 5 gives you a 10% chance to roll an extra time and take the better result. This is similar to rolling with advantage in tabletop games. Instead of relying on a single roll, the game may roll twice and choose the higher outcome. Here is how it works in practice:
- At 6 luck, you have a 10% chance to roll twice and keep the better result
- At 10 luck, that chance rises to 50%
- At 15 luck, you effectively always roll with advantage
This system has the biggest impact around mid-range chances. For example:
- A 50% base chance can become 75% when always rolling with advantage
- A 30% chance increases slightly, but not as dramatically
- Very high or very low chances change less in raw numbers
The math favors improving coin-flip style odds the most.
Negative Luck and Its Penalties
Luck below 5 works in the opposite way. Instead of rolling with advantage, you risk rolling twice and being forced to take the worse result. Key effects of negative luck include:
- Lower chances on all luck-based rolls
- A 50% chance can drop to around 25% at very low luck
- Small percentages become even less reliable
Mild negative luck, such as 4 or 3, is noticeable but not run-ending. However, going deep into negative values severely hurts consistency. Your character becomes much less reliable whenever randomness is involved.
Does Luck Stack Beyond One Extra Roll?
There are signs that extremely high or low luck might add more rolls, similar to rolling three dice instead of two. If that happens, the effect becomes extreme. A 50% chance with triple advantage could reach around 87.5%, while triple disadvantage could crush it to very low odds. However, there is no confirmed limit yet. The game is still new, and exact behavior past the basic system has not been officially verified.
What Else Luck Might Affect
Luck is not limited to crits and combat rolls. Early code findings suggest it also influences weighted item pools and rarity sorting. This likely affects:
- Item quality from drops
- Shop inventories
- Treasure and reward pools
Anything that uses weighted randomness may be influenced by luck. There is still no confirmed data on whether it affects things like equipment durability checks, but it is possible. One unknown detail is the base critical hit chance. Even without modifiers, characters can crit, but the exact default percentage has not been clearly identified yet.
Luck in Mewgenics is more than a simple percentage boost. It changes how the game rolls behind the scenes by giving you extra chances to succeed or forcing worse outcomes when it is negative. Staying above neutral luck improves consistency, while stacking high luck can dramatically swing mid-range odds in your favor. As more details become clear over time, luck may prove to be one of the most important stats for shaping reliable and powerful runs.
