A highly valuable CE for Taunt-based Servants, this CE allows them to gain more healing from supporting allies. At 75% effect when LB’d, it almost doubles the healing effectiveness.
Maid in Halloween should be used on Servants possessing 3-turn Taunt skills, in compositions capable of sustained healing. This CE is preferred over defense up CEs for Servants with hard defensive skills.
the obvious tama cat didn't make the cut for equip? +3k hp on her, plus her NP heals her for insane amounts at higher overcharges. (8700+ hp per turn for 3 turns with max overcharge? on a berserker!) throw in a support like tamamo-no-mae or medea to heal her on the fly and keep her raging with her defense skills even without the NP...
Another good example, my point of cat though is shes literally on the CE, it was made for her and somehow she didn't make the recommended list, sparticus is another great example.
This CE is most effective on servants with powerful self-heal ability like Enkidu or anyone tanky with multiple heal abilities like Marie, Spartacus, Medb.
