Vernier question

[Ember]

theres an ap that boosts ARMS Vernier, what even is that? i cant find any information

[Xaelon]

In this case a "vernier" is a type of thruster. In other words: it's the mech's boosters. So I assume the app boosts the effectiveness of how well a mech can boost, dash. jump, etc.

You can check the "vernier" stats on the head and leg parts. Not all head parts come with boosters, but all legs do.

[HealthBar]

There are 3 Apps that improve the speed of Vernier (=thruster, just as Xaelon mentioned):

Tier 2 Marching On: 8 max. At maximum, improves the top speed of Vernier by 100%.
Tier 4 Boosted Vernier: 4 max. Vernier reaches top speed faster.
Tier 5 Lower Air Resistance: 8 Max. At maximum, improves the top speed of Move, Dash, Jump and Vernier by 50%.

All bonuses are multiplicative.
The maximum value of top speed cannot exceed 600.

EDIT: if you are wondering if they are all useful, yes; especially for speedrunning. Boosted Vernier in particular noticeably improves acceleration.

Vernier should also be related to hovering, such as how slow you fall while thrusters are engaged when compared against weight.

thank you for all the replies
