Stat Days

From TheKolWiki

Much strategic gameplay in the Kingdom revolves around Stat Days. When the moons are in certain phases, gains for a particular stat are increased by 25%. Stat gains from combat are rounded up, stat gains from noncombat sources are rounded randomly. If Grimace is full, Muscle gains are increased and HP recovery from resting at your Campground is doubled. If Ronald is full, Mysticality gains are increased and MP recovery from resting at your Campground is doubled. If both moons look exactly the same, Moxie gains are increased. See moons for exact details. The moons have a 16 day cycle, out of which there are 2 Muscle Stat Days, 2 Mysticality Stat Days, and 2 Moxie Stat Days.

This moon cycle allows players to maximize stat gain for a particular stat through careful gameplay. If a player is attempting to maximize, say, Muscle, they could perform Muscle-gaining activities on days during which Grimace is full. These things might include: using large stat items like Gourd potions or the chest of the Bonerdagon, selecting which food or booze items they consume, or donating at The Hall of The Legends of The Times of Old.

Probably the best and most common strategy is to save up adventures and use them on a stat day. Be sure not to exceed the 200 adventure Rollover limit when doing this!
