A Symbol of Guthix is a grave dedicated to Guthix. It is one of the 6 God-aligned statues, and it lasts for 2 minutes 30 seconds. It can be purchased from Blasidar in Keldagrim for 50,000 coins once players complete the Giant Dwarf quest. It also provides a 3% reduction in costs when reclaiming items from Death.
Although dwarves are also Guthixian, and a dwarf makes this gravestone, they are not mentioned in the shop description.
During the 2011 Hallowe'en event, an advertised Symbol of Guthix read "Nature and the environment your thing? How about this 'green' option?"
