Hero Wars Heidi Event: NO BUFF Best Team for level 210 boss Root of Evil of the current King of the Jungle event. Be careful though if you try this as the account shown uses a maximum Tree of Wisdom! Its best to wait a day or two and see whether or not the developers change the costs of starting a boss battle.

UPDATE:
Some buff levels might be "too high". What I mean is that with some buff levels Rufus might not be revived because the final hit will be a physical attack most of the time as compared to other buff levels where the final hit will be Celeste's magic attack which will revive Rufus.
I just uploaded the proof that the Tree of Wisdom does NOT MATTER. I hope to have a discussion in the comments there about solutions to these issues:

I hope this helps!

IMPORTANT:
If this worked for you, please post in the comments what buff level worked for you. There are many who struggle and every bit of information helps!

A BIG THANK YOU to @Shire-vb6jb for suggesting this team in the comments of the L190 boss!

If you want to support me, a thumbs up always makes me happy! :-)
