Dual Blessing question

[Beetus]

How do dual blessings work in this game?

Can they be aquired even if I don't have a blessing from both fae? (Maybe my friend applies weak while I do stagger dmg)

If I do need a blessing from both fae, can it be any blessing, or does it have to be something that applies their bonus to my attack?

Are some dual blessings more common than others? I almost always get crit + backstab blessing if I have them both, but rarely get other dual blessings.

you at the very least need one blessing from each of the 2 faes in question.
more specifically, if the duo references a certain effect like chill, then you need to have an attack that applies chill. this does not have to be your heavy or light attack tho... as long as you apply chill you are good.
another example, if you want the "combustion" duo blessing which lets all your ignited attacks detonate all stacks of venom an enemy has for extra damage, then you would need at least one attack that applies venom from mab and at least one attack that can ignite from titania.

i dont think anybody other than the devs could comment on your rarity question, but id just assume they are all equally likely and any difference you perceive in that is up to chance.

I've never gotten the combustion duo and have done about 7 billion Mab/Titania runs with every combination of venom, ignite, bile and combustion. It has never appeared once despite thousands of rerolls. Its the only thing left in my codex, and apparently a bunch of other players have the same problem as well, who have claimed the same as me.

Try only picking abilities with venom and ignite, no bile, infect, Mab pets and immolate.
