My apologies, it seems I was mistaken.
Thank you for the information. Radial pulsing from the Bone Ash Hunters? Any idea what drops triangle pulsings? Would it be the Cainhurst Hunters?
A radial Warm gem. That's absolutely bizarre. I can't help but wonder what use the devs thought scaling gems would have that regular %up gems don't already cover, or even odd gems.
On that note, do you want to test something I can't? I imagine you have a bunch of high-grade Cold gems, and my new job takes up more freetime than I used to have. Do Cold gems do anything weird to Tonitrus' self-buff on a high Arcane build? Shouldn't take more than a few minutes.
No need for apologies. The Cainhurst hunters primarily drop triangular radiant gems. I haven't seen any other gem type from them. Perhaps the LHB/RoseKirk Hunters drop them. They're a bit on the rare side, with most NPC's being the Bone Ash Hunter, the Cainhurst Hunter, and the Reapeater-Kirk Hunter, but I think they are your best bet. If not them, then you can try to farm triangular pulsing gems from the Isz Scurrying Beasts. They run up to +4 or +5 hp recovery and can be save-scum-farmed as a group if you find the right glyph.
I think the dev's thought scaling gems would be as good or better than percent gems, but they didn't do their math correctly. Even if percent gems added together instead of multiplying, they would be worse than percent equivalents. I don't believe the scaling gems do anything weird with Toni, but i'll do some quick testing to make sure. I'll edit this post or reply to any new response on here with my findings
Here's the testing with one cold gem (+25.3) and one nourishing gem (+15%) vs one nourishing gem (15%) vs Yharnam axeman:
Toni+10 with 15% nourishing
AR: 248P +130B
no buff charged r2: 569
buffed charged r2: 879
Toni+10 with 15% nourishing and 25.3 cold
AR: 248P + 149B
no buff charged r2: 601
buffed charged r2: 943
Toni+10 with 15% nourishing and 25.3% bolt
AR: 248P + 163B
no buff charged r2: 624
buffed charged r2: 1013
The only way a scaling gem can match a percent gem is on a weapon with 0 scaling at 99 in the scaling stat for that gem. Percent gems multiply and scaling gems add, making percent gems vastly superior
