The Adamantortoises are in the region with cactuar and many Adamanchelids. The Adamantoises wander around the Calm Lands and one can be found in Eden. Adamanchelids are damn weak, but then there are Shaolong Guis and Long Guis...

Oh, and I, too, always build up stagger a little before Highwinding.

Do you think it's more efficient if I keep killing Adamantortoises - haven't completed the circle-missions for the Guis yet - or switch to Adamantoises (especially in Eden)?
