Tips to beat Veteran Arithmetic Enhancer Mek

The Veteran Arithmetic Enhancer Mek has a gameplay similar to the Fontaine Local Legend called the Automated Supercomputing Field Generator. It starts the battle by summoning a strong Geo shield and creating a large Gravity Reduction Field around itself, allowing you to jump extremely high.

Note that the shield can only be broken using Geo and blunt attacks. The latter also includes melee Plunging Attacks, which can be performed by using the Gravity Reduction Field. Zhongli is an excellent option to use against the Veteran Arithmetic Enhanced Mek since holding his Elemental Skill and casting Elemental Burst can significantly reduce the shield's health.

Besides the Geo Archon, you can use Claymore users, such as Diluc, Navia, and Eula. Overloaded reactions also work against the Veteran Arithmetic Enhanced Mek, so using a Raiden Shogun and Chevreuse team can be a good option.

It is recommended to use all of your party member's abilities when the shield is about to break completely since the boss' vulnerability state lasts only for a brief period. This way, you can use this period to dish out maximum damage without wasting too much time. If the boss summons the shield again, break it using Geo or Blunt Attacks and repeat the steps.
