Element Type Chart

Ondan-zensen

Expand

Ondan-zensen (a Touhou LW original) refers to warm fronts―the leading edge of a mass of warmer air that moves in and replaces a mass of colder air. This temperament matches Merlin's heated and energetic music. Merlin is endowed with Metal Phase, as the trumpet is her instrument of choice, and Sun Essence, with her cheerful nature.

The cold and silent Metal Phase resists Earth Phase, because earth bears metal, but it is weak to Fire Phase, because fire refines metal.

The alluring and arrogant Sun Essence resists the diverse and uncooperative Star Essence, but it is weak to the cooperative and indecisive Moon Essence.

Riverside Song

Merlin Prismriver's Spread Shot. She attacks with cheerful melodic notes in a cross pattern. Due to how rivers are formed by nature, the land next to them is often wide and flat―Perfect for performances of all kinds. Perhaps the Prismriver Ensemble also has some concerts down by the river.

Trumpet Soul

Merlin Prismriver's Focus Shot. She attacks with the cheerful music played from her trumpet spirit. The notes played by Merlin are maniac notes―notes that excite and motivate all who hear them. Fitting for a trumpeter, as they are often considered the star of the orchestra.

Nether Trumpet: Ghost Clifford

Merlin Prismriver's Spell Card. She attacks with music reminiscent of the legendary jazz trumpeter. It seems that quite a few musicians of relatively modern music such as jazz and rock have passed away under unfortunate circumstances. No... perhaps the same could be said of musicians from the classical era of music too.

Noise Sign: Merlin Happy Live

Merlin Prismriver's Spell Card. This attack is made up of the notes played in Merlin's solo composition and predominantly features trumpets. It's happy, a very happy attack. But what is happiness? Most likely, it's not something that can just be given to you or that comes to you out of nowhere, but something that you yourself find in your everyday life. Merlin's fans are surely reflecting on the happiness that they have found when listening to this song.

Final Encore - Merlin Solo

Merlin Prismriver's Last Word (a Touhou LW original). Due to popular demand, the Prismriver Ensemble hold many musical events throughout the year. The encore on the last day of these events is always the climax. Merlin's solo portion of the song provides even more excitement to the already exciting occasion, so the audience must be careful not to faint from the frenzy... Though that may be difficult as concerts, by their very nature, are exciting.

Character Ability

Capable of performing maniac notes

Expand

Maniac notes are sounds that excite the listener. Listening to these notes in moderation can help cure depression, but overexposure can make the listener hysteric and aggressive. Like Lunasa, Merlin's solo performances can be dangerous, but similarly to Lunasa's music, the harmful effects are negated when the music is combined with Lyrica's illusionary notes. Merlin's maniac notes directly affect the listener's spirit to make them happy, which may explain why she is said to have the most fans out of the Prismriver Sisters. While there are many reasons to listen to music, it is safe to assume that most people listen to music for the joy it brings them.

Immune to Barrier Status: Paralyze.

DMG from resisted elements 25% DOWN.

Character Analysis

Merlin Prismriver was released on December 6th, 2021 in The Prismriver Ensemble.

Brought into existence by Layla Prismriver, Merlin performs in the Prismriver Ensemble along with her other sisters, Lunasa and Lyrica. To differentiate her notes from her siblings, Merlin's trumpet performs melodies that call toward listeners' emotions and amplifies their happiness to irregular levels until they cannot control themselves. She has an optimistic personality to match the happiness releases from her instrument's performance. Releasing music that makes the audience lose themselves would be dangerous for her own party, so instead Merlin specializes as a Debuff unit that turns the rhythm onto enemies. With a wide variety of debuffs to share, Merlin works hard and stands out as a very serviceable A+ Tier Friend.

The debuffs are the main appeal of Merlin's kit, seen from the affects of her spell cards and skills. She is not shy of applying Freeze to her enemies' barriers, either freezing 2 barriers with her second spell card, Noise Sign: Merlin Happy Live, or passing 2 Freeze barriers to all opponents with her first skill, Jamming Tube. While having no way to break these anomaly Barriers herself, another Friend with Melting bullets can easily synergize with Merlin and work toward Full Breaking the enemy. It helps that Merlin's other two skills, Military Bugle and All-Night Noise, target every opponent as well with the helpful debuffs of Yang DEF DOWN by 2 levels or Evasion DOWN by 2 levels respectively. Unlike her spell cards, her skills can be used repeatedly over longer battles, meaning Merlin can provide debuffs consistently throughout challenging content.

It helps that Merlin does not only weaken her opponents, but can crush them with heavy damage as well. Her Last Word, Final Encore - Merlin Solo, is frontloaded with a 3-1-1 spread so that most of the bullets only need 1 Spirit Power to access. Considering the target's Yang DEF decreases by 3 levels combined with the other Yang DEF and Evasion debuffs from her skills, Merlin's Last Word can serve as a helpful Solo nuke for many farming needs.

Unfortunately, Merlin's performance contains a few low parts to prevent her from being at the top. Outside of her Last Word, she needs at least 1 Spirit Power to access any of her Wood or Water breaks on a basic shot or spell card. Even then, the amount of elemental breaks she has access to are rather low. Having a dual-element Last Word makes it difficult to maximize its damaging potential as well, especially considering how every bullet obtained from 1 Spirit Power is Water while the initial attack is only Wood.

Even without a wide variety of elemental breaks, Merlin gives a great amount of support to the party through weakening the opponents in various helpful ways. The Yang DEF debuffs open opportunities for fellow Yang attackers, and everyone benefits from hitting enemies with decreased Evasion. Merlin is a wonderful Friend when it comes to performing against the enemy, but just avoid those same tunes from reaching your ears...

The values of her Last Word's scaling are as follows:

Hard: 100%/0%/0%/0%/150%/150%

Slicing: 0%/100%/100%/100%/0%/0%

Story Card Recommendations

Spell Card

Ordinary Magician

Bunbunmaru Newspaper

The Witch of Scarlet Dreams

Yang ATK UP helps Lunasa hit even harder, and as such it's greatly appreciated. Otherwise, Yang DEF UP goes well with the high Hard scaling (if a bit let down by her only decent base Yang DEF) on her Last Word, and she can make good use of Spirit Power UP for extra Breaks, as well as damage in the Arena.

Last Word

Thunder Beat

As Merlin already has Yang ATK UP and Accuracy covered, Energy DMG UP is her best bet, with Thunder Beat being a particularly great option. Otherwise, look to Wood DMG UP or Yang ATK UP.

Character Skill Level Up Recommendations

Military Bugle is her best skill, due to the Yang DEF DOWN, and should be leveled first. Secondly, All-Night Noise is great Accuracy support and should be raised next. Lastly, Jamming Tube can wait until you have need for Freeze (such as if you own Cirno with her Freeze Breaks).

Character Strengths

+Can apply a decent amount of Freeze Barriers
+Very strong, frontloaded Solo targeting Last Word
+Solid amount of Yang DEF DOWN to all enemies
+Strong Accuracy support via Evasion DOWN to all enemies

Character Weaknesses

-Can't quite reach the highs of other nukers due to mixed scaling
-Breaks are just average
