Grailmaster — AB

Grailmaster is a medium-sized Heroes of Might and Magic III map of 72 by 72 tiles, set with an underground level and rated hard. It supports four players, two of them human at most, with the other two colors left to the computer. There are no teams. The factions are Castle for Red, Tower and Conflux for Green, Dungeon for Purple, and Rampart for Teal. Terrain is mostly grass and rock, with a smaller share of subterranean ground and no water. Victory comes from building a Grail structure, and a player loses by losing all towns and heroes. The map holds 15 towns, four starting heroes, and many scattered creature stacks, along with 49 random artifacts, 22 mines, and several guarded sites, creature banks, and monoliths. Two timed events and a few wandering trolls and a wyvern add pressure along the way.
