Are there any repeatable challenges that give lapis? I know there's a challenge early on (I want to say in the 2nd set?) that gives lapis as a reward, but are there any repeatable ones that give lapis? I'm sitting on too many levels and I want to get some enchants done. =)
Only the Grinder and Expert Grinder challenges give you lapis as a repeat reward (3 for Grinder, 12 for Exp Grinder). If you have villagers (or use someone else's), then you can trade emeralds for lapis with a Cleric (purple coat) villager.
