The Monk Temple

[Recorde]

I don't have that much experience with alternatives, but I felt the best burst rotation for a boss fight (ie best way to utilize Internal Release) was once I got Impulse Drive from Lancer:

Fully Stack Greased Lightning -> Bootshine -> Flank -> Twin Snake -> Internal Release while moving to Rear -> True Strike -> Impulse Drive -> Impulse Drive -> Impulse Drive (I forget the exact count) -> back to regular rotation as Internal Release ends and/or to save Greased Lightning stacks.

This is as a 20/15 MNK/LNC and I am sure there will end up being other alternatives, but I thought it was effective and looked awesome when I would multi-crit those Impulse Drives.
