I read the post and you are right. You didn't talk about Zoro having healing powers throughout the fight. That was somebody else that talked about that.
Now the question bus whether Zoro will complete all his fights in Wano before it wears off.
Thanks,
Now regarding your question,
Without pushing my agenda on Zoro hahaha, I will be really honest... I see one of two choices:
1- Either it will wear off and pain will be back RIGHT AT THE END of his match.. where Oda showcases Cool Zoro Thriller Bark moment of endurance by muscling through that pain at the very end and delivering the finishing blow in that bad state!
( The most badass and expected scenario for me)
2- Or Oda will treat that plot like the Ivankov-Luffy plot exactly.. where it's never dealth with until all of Marineford war is over already!
I can see both situations... but I prefer the first choice cause it's more badass and Oda can draw some cool shots of bloodied Zoro doing his finishing blow on his opponent
