sac press is purely for crit chance so we can stat stick red crits (might not even need it, need to test once getting [Heat Dagger] and [Heat Dagger] riven)
try replacing edge with [Quickening]
or [Corrupt Charge], get a bit of combo, then activate and reactivate 6 times or so for le infinte combo duration???
or [Pressure Point] with [Sacrificial Pressure] for dagger stat stick initial combo thingy
