Access Requirements
Eclipse Moon is gated behind Perilous Moons quest.
Perilous Moons quest also tends to sit alongside the other Moons of Peril gates, so it is usually cheaper to clear them together than to come back for each one. The boss requirements checklist lists them by group.
Location and How to Get There
Eclipse Moon is found in Neypotzli, where the three Moons of Peril are imprisoned.
Neypotzli via Varlamore, after Perilous Moons. Eclipse is usually fought last in the rotation, so arrive with supplies still in the bag rather than scraping through on what the first two left you.
