Team Recommendations

• Extra or Berserker AoE Damage Dealers are recommended for this battle to help quickly clear out the initial waves of Servants.
• Assassin ST Damage Dealers at the back of the lineup can help deal with Nemo (Santa) at the very end.
• Sure Hit or Ignore Invincible Support is helpful to avoid the various Servants' hard defensive options, including EMIYA's 1-hit Evade that he always will grant to the entire lineup after he dies.
• NP Gauge and Damage Support is useful as usual for the damage support's Card color, to help deal enough damage to overcome the 50% NP damage reduction that enemies will have. The usual supports like Castoria, Lady Avalon, Skadi/Skadi Ruler, Merlin, Koyanskaya, Oberon, Waver, or Reines all work well.
• Since there is no Event Damage CE, Masters can opt for general damage boosting CE options, such as The Black Grail or other damage or hybrid damage/starting NP Gauge CE options.
