Impact 1.9 — HotA 1.3.0+

Impact 1.9 is a giant underground-enabled map of 252 by 252 tiles, built for Horn of the Abyss 1.3.0 or later, and set on a landscape that is almost entirely rock and grass with a sliver of water. Eight players compete on it, all of them human-capable and all starting with random factions, grouped into three teams. The victory condition is to capture one particular town, and a player is eliminated once they lose every town and hero. The author describes a meteor strike in a forest that left surviving lords trying to claim abandoned cities and gather scattered treasure. Among the features are 21 towns, 132 mines and 132 creature banks, 109 randomly placed artifacts, and the Grail. Wandering monsters include many Azure Dragon and Naga Queen stacks, and the map is rated Impossible.
