Step 1: Build [Gauss] as a complete meme to take advantage of his passive reduction to recharge delay + decaying dragon key

Step 2: Get to 100% battery on redline

Step 3: Be passively invulnerable for 92% of the time

Step 4: GROFIT

You will be invulnerable for 100% of the time at 80% battery if Cryogenic Leakage environmental hazard is active (reduced shields). Subsumed Kinetic Plating for Pillage because keeping battery up and shield refreshed is the point of this build.

This is a meme build that is not viable in anything with toxin damage. Maths below in shitty formatting, spreadsheet available here.
