Any Point in Beating Mithrix Again?

[Nox Tenebris]

After beating him a few times and unlocking all the subsequent challenges, is there any point to beating him again? At least obliterating yourself gives you 5 lunar coins, I don't notice anything like that from beating the game though.

Both Mithrix and Voidling give 10 lunar coins when defeated, obliterating gives 5 of them like you said and doing so with Beads of Fealty will give 15, it's up to you to decide how to end the run.

It's also required to beat him if you plan on doing Eclipse.

bullying mithrix is fun
