The Spirit Bomb
Let's go over the spirit bomb combo, assuming you've finished the Main Path: First, you pick up a friendly for 30% reduced ult cooldown. Then, you fly in, throwing our comrade, who receives a 600 barrier, 20% outgoing damage buff, and explodes in a 21m radius upon reaching the ground. When an enemy is hit by the explosion, they're silenced and have -40% move speed for 3.84s. By now, you should have already thrown a kudzu where they're about to go, and are hopefully mid-stoneform, stunning them for 1.92s *IN THE KUDZU* on hit. Once they're within the kudzu for 2s, they're immobilized for an additional 1.6s. This should be guaranteed if you land the stoneform. From the combo alone, that's 3k dmg, with tons of debuffs. If you've completed the Main Path, you can do this once every 56 seconds, so long as you pick up an ally. If you fly for all 27s, your ult is up in 30s or less upon touching down. Now you get to pick your additional flavoring options^^0 items
