I feel like this may be difficult one but Sung Jinwoo guide if possible he's very versatile and there a lot to him so I expect might be bit difficult but would love to see one
For cha's combo, what I did to beat t10 spider with a3, 53k power on cha (~120k total power). Was start with cha, use q 5 times then e immediately after, use basics until e cooldown is at 3-4 seconds left, use my last q to bring the stacks back up to 5 before disappearing and e again. Then id do basics until the stacks run out, shift out to byung-gu and use e, 1 back to cha use q 5 times, e, then ult and that usually brings him down to 40-50 stacks before going up to the ceiling and he still has the anti-healing debuff on him. Then id just rotate around trying to maximize my cha dmg. Would usually be able to win with like 10-20 seconds left.
