METEOR IMPACT
1) FEAST : Swallow at least 10 enemies, and you will have your maximum size.
2) PULVERIZE : Turn into meatball
3) [Catapult] : [Catapult] yourself up high into the air, or double jump and use pulverize, either way is fine,
4) Now watch [Grendel] falling at a high speed, and inflicting impact damage to all enemies within range.
Proceed rolling around and [Catapult] yourself into enemies.
Purely for the LOL.
Now, paint him with bright Pink colour, and put glitters all over his body, and equip [Wisp] noble animation.
Tadaa, you have your glorious abomination.
