The Guild Hall Prophet costs 1p 100 000 sp to buy and 2p 100 000 sp to upkeep, seems like a bug to me. Should be 2g 5000 sp to maintain to be on par with others with the same cost.Didn't expect the NPC to sell altars tbh. Guild level 94 prerequisite is a bit harsh imo.
Didn't see the chronomage amenity.
(bought standard bearer and prophet for HoT hall in Gorowyn)
