A self-imposed challenge 

After about a month of losing interest on it, I did another try at night with a different strategy. Part of it was not used when considering how well it went.
The focus in Field Support is about Damage, Clashing and survival in a party a Resonance utility. The specific choice of E.G.O served as a safeguard in case of dying, which Dimension Shredder would help by stopping Hong Lu from being killed once.
Unlike the many attempts I did over a month ago, I reached the understanding that trying to Evade first was not as bearable, and that Hong Lu would not benefit from remaining untouched either way; the Abnormality Check cannot be won by him even at 45 Sanity and therefore to avoid the nuisance of Stagger Thresholds and low Clashing would require of Corrosion.
