Notes
The Acidified Assassin Set is the 23rd ST set to be released, alongside the Crystal Kunoichi Set and Magmatic Mystic Set. It is the second ST set for the assassin after the Flesh Collector Set.

Equipping the full set will leave you with 900 HP, 332 MP, 70 ATT, 60 DEF, 50 SPD, 75 DEX, 75 VIT, and 60 WIS (assuming you have maxed all 8 stats), along with a dagger that has the range of a sword and deals 5 more damage than the Sword of Acclaim. This will essentially turn the assassin into a sword class that can tank more damage than a normal assassin would be able to and throws poisons often while tanking.
