Generosity and hospitality, and gifts
Rune Bonus: You have advantage on Intelligence checks to estimate an item’s value.
Rune Powers: When 1 minute is spent carefully examining an item while tracing gebu on it, you learn the item’s name and magical properties the same as if you’d cast an identify spell. Alternatively, if 1 action is spent tracing gebu on a willing creature, that creature gains sanctuary as if affected by the spell. The rune maker can’t invoke sanctuary on him or her self. The sanctuary effect lasts while you concentrate, for up to 1 minute.
Rune Mastery Power (8th level): Gebu can be rapidly (1 action) scratched or sketched onto a wall, floor, or other surface of an enclosed space in a way that makes it clearly visible. For up to 1 minute, the rune maker can activate the rune with a command word, provided he or she is within 20 feet of it. All creatures within 20 feet of the rune and with a clear line of sight to it (regardless of whether they can actually see it) must make a Charisma saving throw. Those that fail are affected as if by a calm emotions spell that lasts while you concentrate, for up to 1 minute.
