Where to Find Infinitesimal

Found in the Ancient Sacred Mountain

Infinitesimal is found at the Ancient Sacred Mountain in Natlan's Atocpan region. To get to this place, you'll need to finish the quest, The Frozen, Rekindling Land World Quest.

Once you can freely explore the Ancient Sacred Mountain, you'll have to make your way to the eastern floating island where you will be able to find the Infinitesimal near the broken bridge.

How to Defeat Infinitesimal

Break Infinitesimal's Geo Shield and Force it into Overburn

Much like any Avatar of Lava, Infinitesimal can be forced into the Overburn state by using Pyro attacks until the gauge beneath its HP meter fills up. This will render it vulnerable and it will take significantly greater DMG.

However, in order to do that, you must first break its Geo shield, which can only be broken by either using claymores, the Overloaded reaction, or Geo attacks.

Recommended Team Infinitesimal

Geo Pyro Teams

Main DPS	Sub-DPS	Support	Support
Arlecchino	Navia	Bennett	Zhongli
Itto	Xiangling	Bennett	Zhongli
Mavuika	Xilonen	Bennett	Zhongli

A mixture of Geo and Pyro attacks is the most straightforward way to defeat Infinitesimal, and these teams provide just that. Always have Zhongli in the team to deal significant DMG to the Geo shield and speed things up.

Great Pyro units like Arlecchino and Mavuika will be more than capable of dealing extremely high DMG while filling up the Overburn meter. Once you see that Geo shield go down, wail on the Infinitesimal with Pyro attacks!

Overload Teams

Main DPS	Sub-DPS	Support	Support
Varesa	Iansan	Chevreuse	Thoma
Raiden	Xiangling	Bennett	Zhongli
Clorinde	Yae Miko	Bennett	Thoma

An alternative way of defeating Infinitesimal is through the use of the Overload reaction. Its explosions are powerful enough to shatter Geo shields and dealing Pyro DMG at the same time.

These teams will be able to take advantage of the Overload reaction to its fullest capacity, all while keeping your health in check via support characters like Bennett and Chevreuse.

Infinitesimal Respawn Time

Respawns at Server Reset

Just like most overworld enemies, you will have to wait until the next day for Infinitesimal to respawn. After defeating the enemy, you can fight it again after the next server reset.
