Otto is a Season 6 Shieldbearer. Use Otto when you defend or garrison: the War skill Entrenched Position gives all troops +16% DEF at Lv.5.
Exclusive skills: Arrest Piercing Edge, War Entrenched Position.
Where this comes from: Otto’s hero and Exclusive Equipment screens, captured by MORÖX on S216 (Sep–Oct 2026).
Also from the game: all 6 hero skills (3 Arrest, 3 War) with Lv.1 to Lv.5 values, from Otto’s Skills screens (Oct 2026). Jump to skills.
Not yet measured: star upgrades.
What would change this: a game update to Devouring Mask or to Otto’s skills.
When to use Otto
Otto’s War skill switches on only when you defend or garrison. In any other battle it does nothing, so a trio built for a different battle leaves Otto idle. Read the pick-by-battle table to see who else boosts defending battles.
Exclusive Equipment: Devouring Mask
Shieldbearer HP and Lethality +98% at Lv.7.
Season 6 equipment adds +14% troop HP and Lethality per level, up to +140% at Lv.10 (720,900 power). Maxing it takes 550 parts. In most heroes the rate is set by season, not by the hero: see the Season Rule. Known exceptions: Tyronn and Phoenix.
Odd levels raise the Arrest skill, even levels the War skill
Exclusive skills
Piercing Edge
Basic Attacks have a 25% chance to deal DMG equal to ATK*145% and reduce the target's DEF by 24%.
Arrest skills change how Otto fights.
Entrenched Position
Defending: all troops DEF +10% (16% at Lv.5).
War skills boost every troop, in one kind of battle.
Hero skills
Otto has six hero skills, levelled from 1 to 5. Arrest skills work in Otto’s own fights. War skills boost your troops in the battles Otto marches in. In a rally, a joiner brings only the first War skill of the first hero: for Otto that is Natural Hymn.
