So there are a few diffrent variants of the SAM opener, it directly depends on time the boss is up before going away making him impossible to hit while he does diffrent mechanics or the amount of skill speed you have.

1 sen hagakure opener
This opener falls apart once you hit 965 SKS


The "slow" 3 Sen opener
This opener starts falling apart at 1633 SKS

The "High speed 3 sen opener".
3 sen opener for high skill speed.

If your new to SAM's i'll suggest you read through https://docs.google.com/document/d/1...2tUTgH1o/edit# its a great document for new sam's.
