Скачать или смотреть Fate/Grand Order (NA): The Little Santa Alter rerun: Challenge Quest

I lacked any party composition to get an attempt of a 4 turn clear, but I had the roster to at least clear it.
Several things to note,
Santa Alter will buff any of the reindeer mooks if they are left alive when she comes in, try to eliminate the reindeer with a AOE servant before she swaps in (and likely will do so, the Assassin reindeer has the lowest hp pool)
With each break bar broken, Santa will buff herself with 90% card resistance of Buster, Arts and then Quick. These buffs are permanent and are applied ONCE, however they are REMOVABLE, Buff removal servants such as Jack are going to be clutch, which is why I kept Jack on the backline.
The plan was to nuke the reindeer and then ride out Shiki's damage until Jack was brought out. If Shiki was still alive, I'd try to have her finish the job. Waver and mashu were supporting buffers while the support Merlin amplified raikous aoe damage to clear the waves faster
