Endure Effect / Frenzy (Berserk) against long/magic skills.

[Kusan]

Hello, I have a problem with Endure skill. When I get consecutive hits loses the Endure effect. What I do is that skills such as Acid Demonstration skill has the same effect when you are in the Enduring physical state when you receive individual blows.

Example:

Melee Attack (Endure Works): 

Multi-Hit Attack (Endure doesn't work):

 

Sorry for my English!
