Genshin Impact - Geo Hypostasis Elite Boss
If you need ascension Geo materials, Geo Hypostasis is the place to get them. Located on some secluded islands, you'll need to glide from far above to get here the first time to unlock the teleporter.
As a boss, Geo is perhaps the easiest of the Hypostasis foes - just whack away at his platforms and be on the lookout for a small crystal cluster that he pops into play from time to time. Slay the cluster to create an earthquake shield that will protect you from harm, as his attacks are highly damaging. As with the other Hypostasis creatures, Geo attempts to heal when critically wounded. All you need to do is punch those geo towers down and that's the whole fight!
