I use the egg to raise the value of Temperance. So I will use it several times.

I have only had it a few times as eternal though.

There are a few jokers that can scale based on the total value of your jokers, but it’s pretty niche.
If you get yourself a sacrificial dagger it becomes a very wonderful synergy
I thought that didnt work because the dagger has to destroy the joker first to then gain its mult but it can’t destroy permanent jokers so it doesn’t trigger at all?
I never tested it, but I was under the same assumption.
Yes, I check the wiki and sadly you are right, the dagger is already such a mediocre joker imo so I told myself something like this was possible to convince myself it’s not that worthless :(
You can still pair it with xmult just remember to change the order before choosing the blind
Does that actually work with eternal jokers?
It can be OK with Swashbuckler and some multipliers.
