Many dangers reside deep within the dungeons of Krül, but on rare occasions delvers may find succor in small hidden shrines dedicated to a forgotten cult. While the tenants of this warrior faith have been forgotten (as have their origins), rumors persist amongst adventurers of the power that still resides in this underworld chapels.
A Greystone Chapel may be identified by the imposing portal which bars entrance, a skull of monstrous proportions whose distended mouth holds a trap door. Should a Fighting Man approach such a portal with reverence, there is a 50% chance that the trap door will swing open. Beyond the trap door is a small grey stone cave with a bare altar. Fighting Men which pray at this altar will be imbued with divine favor.
If favored by the unknown gods of the Greyskull Chapel, the Fighting Man may call upon their blessing in the future. By raising their weapon above their head and shouting, "By the power of Greyskull!" they will find themselves imbued with incredible strength (equal to a potion of Heroism) as a bolt of electricity strikes their weapon. When this incredible transformation occurs the Fighting Man will become more tan and muscular and all clothes worn will be replaced with a pair of fur underwear (excluding partial armor). Clothes worn will return at the end of the effect.
Additionally, while under the effect of the blessing, Fighting Men may shout "I have the power!" to inflict maximum damage upon landing a successful blow. This effect may only be used once.
Fighting Man can only call upon such a blessing once after receiving divine favor, and will find the doors of the chapel will remain barred after their initial visit. However, if a similar chapel is found elsewhere in the underworld the Fighting Man may approach it independently and receive an identical blessing.
