EDIT: Solved! Thanks to everyone who commented. Confirmed this is a straight nerf for the elemental portion of Nebulis down from a max of 600% to a max of 450%, power of the sceptre is now more concentrated in its implicit modifiers.

I run the Arc Ignite Elementalist guide that makes use of the known interaction of double and triple dipping on elemental conversion (stack all resistances to 90%, use nebulis and 2 call of the brotherhood and possibly cold to fire depending on the patch) for a total of 600% increased damage. At least thats what Nebulis USED to do for the build.

The math, previously, was (assuming a max roll on cold and lightning mods)

• 20% damage per point above 75

• 15 points between 75 and 90

• 2 elements are affected because of the conversion

• 20*15*2 = 600% increased total, POB confirms this

Now there was some concern in my Discord that the change shown in the patch notes/attached image actually represents a nerf down to 450% increased (setting aside the implicit mods for the moment and focusing on the resist part), but....I don't think so. Please help me double check my logic but I THINK this is actually a fairly massive buff to my case-use. But I don't want to go off to the races without some more eyes on this for a sanity check.

At max rolls:

• 10% damage per point above 75

• 15 points between 75 and 90

• 3 elements are being counted

• 2 elements are having that total number applied to them, because (at least in the current state of the game) all generic "increased elemental damage" mods apply at all stages of conversion. You can check yourself; Sadist and elemental cluster jewels make it clear.

SO....assuming they haven't stealth nerfed the multi-dipping of generic elemental mods (and they may have, who knows) the math would actually be 10x15x3x2 = 900% increased.

And that's leaving aside the possibility of adding cold to fire back into the build (it left when shaper of flames got changed in 3.26). With cold to fire, that last number 2 is actually something more like 2.8 (50% cold converted plus a bonus 30% cold as extra), meaning over 1,200% increased with perfect rolls. Plus the new implicit shenanigans.

Am I missing something here? Is this as crazy as I think it is? Did I somehow double-count something?

Increased elemental damage as a modifier participates in calculations once regardless of conversions made.

POB Disagrees with you. Maybe POB is bugged, but it thinks generic elemental damage counts each time, take a look. https://pobb.in/0urZBgFhh1-B

Look at the lightning and cold % increased sections. Sadist is fully counting for both, which wouldn't be possible with your interpretation.
