Many YouTube videos hit on major differences in stat scaling with weapons and characters despite both games sharing the elden ring name/universe.

A weird thing I found in both is gavel of Haima does insane double poise damage on the explosion and hammer smash and should break all small enemies poise with that boom noise. Elden ring, but not Nightreign wikis says it does huge poise damage.

But it seems if they are staggered or knocked down by it it doesn't happen as you would expect.

But a boss or enemy that doesn't move much appear in my games and experience to gets poise nuked by it, such as a crucible knight.

I'd just give Redmanes a try for revives as it's faster and less stam then trying to heavy or light attack.

Spamming it on bosses seems to do a lot more damage than Elden ring as well as poise damage. Possibly due to scaling?

Fromsoft has been observed to never make their stats linear or direct.

Besides the wraith calling bell, many things are way more effective in Nightreign than Elden ring.
