Boss Statistics

Overview

• Fight once again against the Wishing Star in this final Challenge Quest! The boss is a Foreigner with 3 HP bars (1.2M, 701k, 1.7M HP).
• The boss starts by placing a multitude of 50-turn buffs on itself, which include 25k HP regen, chance to inflict Charm when attacked, Guts (1 time, 50% HP Revival), NP Damage Resist +50% (5 times), and Debuff Immune (10 times).
• The boss has special passives that allow Masters to progressively reduce the turn count of the starting buffs:
• Critical Hits on the boss will give it a small Crit Rate +5% buff (3 turns), but will also shorten the boss's initial buff durations by 1 turn, and add 1x stack of a hidden [Breakdown] debuff.
• NPs on the boss will give it NP gauge +1, but also shorten the boss's initial buff durations by 3 turns, and adds 2x stacks of the hidden [Breakdown] debuff.
• When the boss reaches 15x stacks of [Breakdown], the boss will be stunned for a turn and get a Damage Resist -30% debuff for a turn. As a result, Masters are encouraged to continue to attack the boss with Crits and NPs until they can activate the debuff on the boss.
• On first break, the boss removes all Crit Stars from the party, removes 3 latest buffs from the party, and debuffs Star Drop Rate -100% (5 turns), NP Gain -50% (5 turns), and increases its own Damage Resist +50% (10 times, 5 turns). Note only the Damage Resist buff is unremovable, while the other buffs can be cleansed.
• On second break, the boss will begin gaining +2 NP charge per turn, ATK +30%, NP Damage +50%, and DEF -50% for 5 turns, all of which are unremovable.
• The boss has a skill that can drain 20% NP from the entire party, which also can give it up to +3 NP charge.
• The boss's NP hits AoE and ignores DEF. It also will debuff NP Gain and NP Damage afterwards for 3 turns.

Team Recommendations

• This boss can be solo'd with multiple Servants (see video links).
• ST Alter Ego Damage Dealers are excellent choices for both Offensive and Defensive Class advantage since the boss is a Foreigner. Alternatively, other Classes that have Offensive advantage, such as other Foreigners, can also work.
• NP Gauge and Damage Support is ever useful to help the damage dealer defeat the bosses more quickly. The usual suspects including Castoria, Lady Avalon, Skadi/Skadi Ruler, Merlin, Koyanskaya, Oberon, Waver, or Reines all work well for their respective Card types.
• Bringing the Event Damage CE Hot Springs Ball Games on the main Damage Dealer is highly suggested, and will help with bringing the boss's high HP down more quickly.
