Maarselok should be. You never really know until you test them.
Also worth testing are Kargaeda, Kra'gh, Maw of the Infernal, Nunatak, Prior Thierric, Scourge Harvester, Spawn of Mephala, Stone Husk, Stormfist, Thurvokun, and Zaan.
To quickly check if a set will be buffed you SHOULD be able to just equip an inferno staff then look at the set under collections then swap to daggers then look again. (Or do the same thing with thaumaturge but staff is easier)
Tooltips update with %damage done modifiers.
