Where to find these spells?

Spoiler Alert

I haven’t completed KB yet but I’ve started a number of games and this is the second time I’ve reached the Freedom Islands. On the Eastern Islands there are a couple of quests where I’ve I had the chance to buy cool spells after I completed them. One is bringing back Indulgence for Captain Black Eye. He had Sacrifice for sale this time around though I’m not sure if he always offers it. Both times now after buying the scroll from the Sorcerer’s Tower and raising the Moon Ghost off the NW side of the island he had Invisibility for sale but make sure you have sold or dropped your spare scrolls so you’ll have room to buy it. He often has a nice artefact for sale also.
