Overview
As you know Sora's passive converts health to damage and damage to health. So if you build him with as much health as possible then he will deal more damage.
Strengths
More health = more damage. Just make sure to prioritize squishy enemies.
Weaknesses
Sora can still be weak despite having too much health. Also don't waste ultimate as Sora is useless without his ultimate.
Healthy Sora
You can adjust it based on the enemies.
Healthy Sora
So despite it being a healthy Sora build I choose fighter emblem as he lacks will be lacking sustain.
Healthy Sora
Tank emblem is viable but will be lacking sustainability.
Battle Spell
Flicker is ideal for Sora as he lacks mobility.
Early to Mid
Sora is dominant on early to mid game but fall off on the long game. So like I said don't waste ultimate, use it wisely to target backlines or squishy heroes.
