I used a level 20 Velo, 20 Dracocera, 20 Indom (unused), and 23 Quetzorion (used, but it was for safe measures)
Use velo, pounce, get SV’d, swap to Draco, fail stun, attack and die, go back with velo and pounce, die, and use Quetzorion to finish the job.
You can do this with a level 20 Velo, 15 Draco G2, and possibly something else that is either faster or breaks shields, preferably Indominus. Pounce, swap to draco, break shield and die, pounce, die, cloak, rampage and that should be it.
I beat it, so I’m not sure if that works. Share your strategies!
