Oliver Fog
Who is Oliver Fog?
Oliver Fog is a 4-star Star-afflatus defensive buffer who protects his team by granting [Sturdiness], DEF, and Mental DEF buffs through his mass buff skill. His Insight passive gives him a self-regenerating shield that reduces the damage he personally takes, and he has a leech rate built into one of his skills to keep himself alive. He drains HP at round end as part of his insight mechanic, making self-sustainability a balancing act. Defensive buffers have fallen out of favour as premium sustain options have become stronger, and Oliver Fog is rated low on tier lists as a result, but he remains a functional filler for players lacking better options.
スキル概要
Single-target attack with a built-in leech rate — heals Oliver Fog based on damage dealt, offsetting his HP drain mechanic.
Mass buff — gives all allies [Sturdiness] stacks and increases all allies' Reality DEF and Mental DEF by up to 20% for 2 rounds.
Oliver Fog gains a personal shield that reduces his own DMG Taken by 20% at round end; the passive also costs him HP each round, requiring the leech on Skill 1 to stay healthy.
ビルドガイド
🔮 最適遺物/エコーセット
Resonance: ATK% to support his leech rate on Skill 1 and keep him alive. HP% as a secondary to offset his per-round HP drain passive.
⚔ 最適光円錐/武器
Remaining Absurdity (signature anecdote, prydwen): Grants 10–20% Incantation Might on attacks while Oliver has a shield — which is always. The Reality DEF substat is not ideal but the Incantation Might is a solid bonus. His Bounden Duty (budget): Meaningful base ATK increase that directly compensates for his chronically low 4-star stat line.

よくある質問
Why is Oliver Fog rated so low on tier lists?
Defensive buffers as a class are poorly valued in the current meta because premium healers and supports provide far more impactful team support. Oliver Fog provides modest DEF buffs and [Sturdiness] but no offensive utility, making him a below-average choice compared to almost any 5★ or 6★ support.
How does his HP drain mechanic work?
His Insight I passive drains a small amount of HP at the end of each round. His Skill 1 Working Hours has a built-in leech rate that heals him proportionally to damage dealt — using Skill 1 each round is essential for keeping him alive across a long fight.
Does [Sturdiness] from multiple sources stack?
[Sturdiness] stacks are additive — if Oliver Fog and another character both apply [Sturdiness], allies absorb multiple incoming hits before losing the buff. However, each stack only absorbs one damage instance.
