Red Doppelganger (2nd fastest strat?)

The actual fastest strat for the speedrun is using Satelite (Yellow Crystal), but this is probably the 2nd fastest as long as you get the entire 53 hit combo with Grand Cross. This strat loses 2-3 seconds over Satelite if you get full combo and probably 3-5 if you need a few extra hits. If find this to be significantly easier than the Satelite strat, this strat is probably better than the Cross Blazer Stun-lock because you can actually get a combo going with Grand Cross. In theory, you might be able to save an additional 1 second if you get good cooperation from the boss, but that would only come from RNG.
