Grail

The Grail, or sometimes referred as ultimate artifact, is an object that is typically hidden somewhere on the ground of Adventure Map. In order to recover the Grail, a hero must dig it out of the ground. Only one Grail may be hidden in the Adventure Map. However, it is also possible for a mapmaker to set hero or several heroes to carry the Grail in their backpack.

When the Grail is buried into the ground, clues to its location can be found at obelisks. Every obelisk heroes visit reveals a part of the Puzzle Map, which shows the location of the Grail marked with X. Typically the X becomes visible when when the entire Puzzle Map is revealed, but occasionally it will be showed before the last oblesiks is visited. However, it is often possible to guess roughly the area where the Grail might lie, and systematically start digging it. In fact, the AI at hard difficulty levels start digging the Garil even if only third of the Puzzle Map is completed.

When the Grail is taken to a town, a structure specific to that town will be built, and the town cannot build another building that day, though the grail building can be built even if you've already built a normal building in that town that day. The primary bonuses that all towns get are an extra 5000 gold and 50% additional creature growth.

Notes

• If the hero carrying the Grail Retreats, Surrenders or is defeated in battle, the Grail is lost forever.
• If the map has no obelisks, it is completly impossible to find the grail (even if every single block on the map is dug on). Also, using "nwcoracle", a cheat that reveals the puzzle map, will have no effect and the puzzle will not show anything.
