Being /DNC at level 80 is great!
You can now use your steps to reverse flourish.
and with each step you can get 12TP back
so with the total steps you can have (5) x 12Tp = 60Tp
just like a natural DNC.
Think of it as insurance if you need that last tick to WS
Anyway, by this being an added factor to SAM this makes Meikyo Shisui (Light) easily obtained w/o usage.
I just wanted to point this out. This goes for any job /DNC btw..but I feel that SAMs benefit from it most since we can now basically hold TP.
