So the basic one increase attack power a wooping 3%
wow

There's a Greater version of this

Appears to work on Magma Blade's AoW, Magma Shower. I absolutely slaughtered that giant blue golem on the cliffside near the Minor Erdtree in Caelid.

First time trying it against the golem I melted his health and would stagger him repeatedly before he could get off an attack. This talisman pairs beautifully with an upgraded Magma Blade!

Does this work with Nebula, the Wing of Astel weapon skill?

fun fact : it seems hitting the fire cannons/balistas etc also triggers the effect, situational but food for thought

The short spear and cleanrot knight spear both appear to activate the insignia if you land the double thrust R2

How well does this work with barbaric roar R2 Chain?

"Effect activates after 3 hits, regardless of weapon class."

^Can someone clarify this for me? Is that three hits to activate the third tier, or three hits needed to activate the FIRST tier?

People are spreading misinformation, this doesn't affect Gravity Bolt weapon skill at all.

doesn't affect continuous damaging spells like comet azur and meteorite
