Genshin Impact 6.4 Stygian Onslaught Guide: Boss Mechanisms
To defeat every boss, you have to learn their mechanism; otherwise, you can’t defeat any bosses, even with perfect artifacts and their best weapons.
1. Mandragora Boss
It’s a local legend from Nod Krai, released in the Version 6.3 update. Particularly, this boss is weak against Pyro, Electro, Electro swirl, and Pyro swirl reactions. Never use Dendro against this boss. This boss has 205% Dendro res in the normal state.

This boss mechanism is simple to understand. Mandragora Boss has 80% resistance to all elements in its normal state and 205% against Dendro. This boss also summons 10 minions during battle, and we have to defeat at least 8 of them.
If we defeat 8 of them, this boss will be stunned for a few seconds and also lose 70% resistance to all elements. If we aren’t able to defeat those minions in time, then the boss will deal an AoE Dendro attack and come back with full resistance.
2. Knuckle Duckle Boss

It’s a world boss from Nod Krai. This boss is weak against Electro Charge and Lunar Charge reactions. This boss summons multiple mini Knucle Duckle and creates a shield. To destroy that shield, defeat all mini Knucle Duckle in time, and the boss will be stunned for a few seconds and lose elemental resistance.
3. Secret Source Automation
It’s a world boss from Natlan. This boss is weak against rapid Cryo attacks. Secret Source Automation has a cryo bar. To deal damage, we have to use cryo attacks, which reduce the cryo bar and allow us to deal damage.
