Duet Night Abyss Best Phantasio Build

Phantasio is an Umbro DPS playable character in the game. He primarily excels in Skill Damage output. In terms of weaponry, the character uses a Shotgun for ranged attacks and a Greatsword to deal with enemies up close. His build makes him a great choice when going up against powerful solo enemies, such as bosses. However, he doesn’t perform nearly as well when faced against enemy waves.

Pros	Cons
His Ultimate lets him enter the Bestial Fury, which deals massive Skill Damage to targets.	Isn’t nearly as reliable when facing off against waves of enemies.
His Max Sanity also transforms into his max Attack. So, the more Sanity he has, the greater his damage output.	–
Higher Intron Levels enables him to dominate fights against bosses. His effectiveness increases the longer such fights continue.	–

Team Composition for Best Phantasio Build in Duet Night Abyss

Phantasio works best when he’s paired with Berenica and Tabethe. Both Berenica and Phantasio are Umbro Element units, and their synergy boosts both of their Attacks when placed together. On the other hand, Tabethe provides Skill Damage buffs to both of these DPS units, empowering them to deal increased damage to targets.

Umbrelf is the best Geniemon choice here, because of its ability to increase Umbro Attack by 2.4%. therefore, this Geniemon would benefit both Phantasio and Tabethe.
