Like many I wrote off Physical Sunder Charm as mostly not worth it for Barb since Berserk and/or decrep/amp procs are so effective against PIs and don’t have nearly the draw backs.
Discussion in general about Grim Ward prompted me to research it a bit. It sounds like it actually works the same was as Amp in terms of reducing physical resistance to increase enemy damage (although it has more limitations b/c the target needs to be able to be feared).
In general Sunder Charms seem to be much more effective when you are able to then further reduce the broken immunity using additional items with -res. Cold Mastery reducing cold res is the obvious example of this being super effective.
Does Barb have something similar (albeit worse) with Grim Ward + Physical Sunder being able to reduce it down? Now that Find Potion often gets more hard points due to the bonus it gives to FI, and it also gives Grim Ward additional damage bonus, I’m wondering if there’s an opportunity there?
I’m a NL character since I don’t have enough character slots and don’t want to delete my NL characters that I enjoy playing, so I can’t really test, so it’s just theory crafting at this point, but wondering if people have thought about the interaction with Physical Sunder much? Since Grim Ward in general isn’t super popular, it seems possible that it could have flown under the radar by a lot of Barb-bros.
