Machine Assassin - Master Arts Review

10Fatal Bite★★・・・
20Viral Vector★・・・・

There are a few high-level monsters that can be Debuffed but it since it is random, you will have to depend on your luck. It is not necessary to learn regardless of which class you aim to get because of its low damage output.

15Anti-Erosion SystemAnti-Erosion System★★★・・

Since Debuff is often ineffective against high-level enemies and Cursed Edge can only be used in few cases, it is not necessary to have the Defenders learn it. However, it is good to have Defenders learn Debuff resistance but it is not a high priority.
