I do, but he's a unique Healer, so I'm looking to build him differently.
Though at this point, since I have enough keys to MUB both, I might as well, cause he's gonna be super fun when dual prints are a thing.
How much does he heal from the normal healing of Call of Chaos?
I'm kinda bored and have some free time at work, so let's think through this a little.
Here's his info.
Looks like at level 80, 45 mana (so level 3 skill), 5.3.0 weapon, MUB Nidhogg, maxed altars and library with 16/16 dojos, Volcanic Queen's stats because we're assuming High Jupiter print... he'd have 2641 HP, 1963 STR.
If I'm doing this right... his heal would do, by the
healing calculator, 238-263 healing by default. Normally he'd heal about 106 more from the lifesteal, twice, before being capped, so that's 475 at most as long as he can hit for 3533. Powered up by skill 2 that 106 doubles to 212 before it applies twice, so that'd be 687 at most as long as he can hit for 2355.
You add Ruse to it in a second slot, assuming its stats are added, MUB so 13% potency buff... well, he's 2884/2032 now, normal heal is 290-310, lifesteal is ~115 twice for 540 max if he can hit 3833, powered up 770 max if he can hit 2555.
assuming I did math/input in the calculator anywhere near correctly
So... I'm not really sure he's worth building that much differently than a normal healer? Maybe I'm wrong, but at most I feel like you just want to be able to hit enough to max lifesteal... but it's not like a better option than Nidhogg exists for dark healers to begin with, so your HP and strength balance is largely decided for you. So I guess the question is if you need the second print to do enough damage to hit the cap so that the lifesteal makes up for not having buffed potency instead; if you'll already hit enough then potency is better? And I feel like hitting the cap won't be too bad... especially if you're always using skill 2 first, since that lowers the requirements (9% damage has to hit 8% HP, instead of 3% to hit 4%) and buffs your strength too.
EDIT:
oh also... assuming skill haste is literally an SP gain multiplier, then simply having Nefaria in the party would get you skill 2 in 2 combos thanks to her default +8% co-ability
MUB Heralds is 5%, which would require another hit still
