Just for context the text for the changed ascendancy node Ngamahu's, Flame's Advance is as follows:

Non-Unique jewels cause Increases and Reductions to other Damage Types in a Large Radius to be Transformed to apply to Fire Damage

And that made me think, if this mechanic works similar to other transformation jewels as this example this effect can overlap making the scion wheel pretty attractive for a lot of increased dmg.

I created a scuffed pob (it's a pobb.in link as for some reason pastebin did not work for me) for a RF build to show this in action, pob seems to correctly transform physical/lightning/cold damage but not stuff like projectile or spell.

So i did some quick additions and if i am not mistaken that tree should provide 610% increased fire damage after all damage type transformation are taken in effect.

Personally i think this is a very solid damage boost for no gear/cluster investment, not to mention RF really likes using rare jewels for more dot multi/hp so there is no tradeoff here.

Let me know what you guys think, did i get something wrong or is this setup still not worth the ascendancy + passive points investment?
