Instructions: This program calculates whether a creature at a given position (x,y) will have an upgraded stack of units or not. The calculation is accurate for any standard-sized map, and even works for modded XXL-sized maps. Please keep in mind that the upgraded stack will vanish after the first fight of every week and will stay missing until the start of the next week. The output is given for both overworld and underground creatures, since each uses a slightly different formula. Also keep in mind that battles in the underground will always take place on dungeon-terrain, regardless of the choice made by the mapmaker - the only exception to this rule is water as well as elemental plains.
