So this is the end of holloween rerun?

Not sure if it's the end or not, I also missed the initial Halloween event too so not sure if there's a difference in NA's scheduling or what not.

I'm trying to get one more copy for HP myself to MLB, though I got 2 drops of Maid on the 40AP node, and I really find it great on my self-healers like d'Eon, Ruler Martha and Nero. The event doesn't have much difficult enemies but as a benchmark, I ended up finishing every node with them at full health, the heal amount is insane.

I'd say farming alone is worth it at least to trade the currency for cupcakes, and then trade it for QP since we get a decent amount from them per AP, with the mat drops and CE drops being a huge bonus.

Maid is way too niche to be good, no point in MLBing it unless you want to specifically build a team with healing as a focus. Definitely not worth the apples. If you have spare AP and want to be a perfectionist, there's no reason not to farm some free quests to try for MLB, but otherwise don't bother.

Also, rerun will be around for another 6 days.

For what you MLBing Maid in Halloween ? If you have servant with strong self recovery/Healing skill go get that CE. Personally i use these CE MLBed Maid, some of my servant have strong Healing skill like OG Nero, Marie Antoinette, Tamamo Cat, D'eon, Medea Lily and David. I also use Art team because they're not also famous for NP spam but their Survivability too so this CE is Vital for my team.

Or it is only for Collection ? Remember this ! Farm itself is another part like Gacha and it testing your perseverance to another level.

Here's my comparison :
SSR/5 star have 1 % chance to get per roll.
SR/4 star have 3 % chance to get per roll.
Halloween 5 Star CE Have the highest rate of 0.8-1% chance to get per run.

If you really need this CE go for it, but if your servant and team comps not supported by this CE don't even bother getting it. 3 Maid CE on the shop is enough to help for clearing the event shop.

The choice is yours, i only give advice here.

It's a really meh CE. The extra healing doesn't even guarantee an extra hit from enemies which you actually care about. Better off equipping a guts CE which actually guarantees your survival.

Most importantly, the heal only affects the equipped servant's own skill. So if you have maid equipped and you expect Medea Lily to heal you for crazy numbers, you are in for a badddd time.
