Add point analysis:
It is tough to point out the Double Poison stream in the current version. After filling Deft Combatant, Ruthless Guile, and Somersault Kick later, relying on the flail to trigger the five-layer Poison Edge effect, Poison Vial and Poison Edge need to stay on BOSS all the time. Two Poison damage effects can cause a lot of damage, plus Vicious Cuts trigger the Ruthless Guile effect, Mind Stealer is used to cancel the Somersault Kick and the Poison bursts as much as possible in the last second, because the 5-layer Poison Edge plus Poison Vial effect The Poison injury is very high, the Level 1 Poison burst can't hit very high damage, or when the Poison Edge effect is coming to an end, A will have a Poison Edge to continue the 12-second Poison Edge effect.
Output loop: 
After starting the BOSS battle, first throw Poison Vial, use Mind Stealer to cancel Poison Vial and then shake, then level A. If you are lucky, trigger Passive Skill to hang directly on Layer 5 Poison Edge. If bad luck does not trigger Passive Skill effect, then use Vicious Cuts to poke to one-third of the SP value when Somersault Kick+Poison bursts out combo damage, continues to fill Poison Vial and then loops. Double Poison Build needs a lot of attention, and it is fortunate. The Passive luck Skill can strengthen Vicious Cuts and do a lot of damage, and continue to fill up the Double Poison effect, but because of the lack of level, there are fewer skill points. Take the real most significant damage from the Double Poison stream.
