Now, the explanations associated with the commentary in the video.
1) Visual bug
This is pretty much the consensus - double casting is only a 'visual bug' and does not deal any damage, and neither do the spheres that the visual bug creates. Obviously, this visual bug is caused by an improper execution of the double cast. Notice that the first three orbs only appear after gravity sphere has dealt it's full hits - this is why the bug happens. You MUST cast TOExi after the very first hit of GSphere, and the orbs MUST be on the field before the final 3 hits of gravity sphere end. There are 4 hits for gravity sphere - 1 when hitting the object, and 3 when exploding on the ground.
Cast first TOExi when hitting object, and second TOExi before the ground explosions end. <--I will most likely repeat this so that it sticks.
2) Common Mistake
This mistake is caused by pressing the hotkey for TOExi too late. There is no opportunity for TOExi to be refreshed a second time.
3) True Double Cast
Ahhh, the fabled double cast of TOExi properly executed. You can tell that is properly executed because it deals 52 hits total - 4 from GSphere, 24 from first cast, 24 from second. You can also notice that both cast are in fact dealing damage, and that all 6 spheres for force gravity are also dealing damage.
You MUST cast first TOExi when hitting object, and second TOExi before the ground explosions end. The ideal way to execute is having TOExi refreshed when GSphere hits the object, having all orbs out from first cast before the explosions end, and then TOExi will be refreshed from the explosions allowing you to cast again.
Now, the second part of the video shows you how to practice. You can practice by blinking backwards so that it gives you a bit more time for the projectile of gravity sphere to hit. Once you get the hang of it, you can blink forwards like I demonstrated in the first part of the video. Please note I am constantly refreshing Force Gravity from the blue circle in the BTG.
1) Common Mistake
Again, if you click the hotkey for TOExi too slow, it will not have an opportunity to refresh.
2) True Double Cast
Notice that even though I hit the closest part of the hit box, the first cast of TOExi was on the field BEFORE the final hits of gravity sphere (the explosions).
This is hard to notice without explanation. I had cast the first TOExi in order to double cast, however I did not click for the first cast fast enough to cast the second TOExi. Be sure to spam the hotkey in case of lag. Lag can make this happen if you only press the hotkey a couple of time.
4) SECOND Version of True Double Cast
This is also hard to notice without explanation. If TOExi IS OFF CD, it is possible to cast TOExi BEFORE gravity sphere hits at all, and then have TOExi refreshed once gravity sphere hits. Take note that only 50 hits were made. This is because the orb CLOSEST to me was too far from the boss. The first two hits of each orb have the smallest AoE. This isn't really important, but I added in a brief explanation to make everyone aware. You can still be relatively far from the object and get most hits in.
With a +1 plate to reach r20 TO, and a +20% damage plate for TO, as well as a -20% CD plate for gravity sphere, you can deal roughly 20,500% every 4.5 seconds by double casting. This is obviously the highest dps skill for sorcs (all things being equal). ***EDIT*** I say around 20,500% because object may move or one orb might be too far when casting. I also added the damage of GSphere into this 20,500%. I don't see any real reason to be nitpicky about this number, since it's not the main premise of this guide.
I hope that this guide has been helpful, and has laid some arguments to rest.
****EDIT 2**** TOExi is the only Sorc exi that can be double cast with both casts having damage consistently. I also do not have time or patience to teach in game. Please no more mails or pms.
****EDIT 3**** Too tired right now. I forgot that Fireball Exi can be double cast under SPECIAL conditions, along with Spectrum Exi.
