The reason that you have altarpieces from other tabs working, I think it's because of a bug with how the items are placed when you have dlc + true torment altar pieces.

But there are some weird ones that are giving the incorrect bonus too, like there is one altar piece that certainly was made to be used with the dual swords, but gives bonus to Veredicto.

Cobijada Mayor + The Family = Sacred Shelter

After receiving several blows, emanate a powerful wave, inflicting damage on enemies around you

Castula and trifon resurect you with all flasks and full guilt. I was hoping for better guide

The Mercy + Tirso = Ascending Wrath:

Each successful blow with any weapon progressively increases damage inflicted for a limited period of time.

Crisanta and Sisters activating Gregal's might be a glitch, since Favors should only activate with pieces from the same tab.

Looks like The sisters and The family gives you The Gregal favour (increase Veredicto,strengh)

If you use crisanta and the two sisters you can increase even more the damage of veredicto.
So you can have 2 resonances that increase veredicto damage

Only new resonance I've been able to confirm is Castula and Trifon now granting one auto revive. Only missing new figure is lump of gold reward, so haven't been able to test if that interacts with anything yet.

Is there new resonances from dlc?

very informative and useful, thanks
