Horropedia Reverse 1999 Guide: Skills, Insight Materials & Team Comps

Horropedia stands out as a 5-star Mineral Afflatus character in Reverse: 1999, renowned for his Mental Damage output combined with powerful dispel mechanics and debuff application. Released in Version 1.4, he targets buff-heavy enemies effectively as a sub-DPS or utility support, though his niche role makes him less versatile in the broader 2026 meta dominated by hyper-scaling DPS units.

Comprehensive Character Overview

Horropedia's design revolves around punishing enemy buffs through integrated dispel and conditional damage spikes, fitting the Mineral Afflatus's strategic playstyle. He entered the game as a counter to tough Limbo stages and events where foes stack [Status Up], [Counter], or positive effects.

• Rarity: 5★ (Standard Banner pullable)
• Afflatus: Mineral (Resonates with Star Afflatus enemies)
• Damage Type: Mental (Scales well against Reality/Spirit defenses)
• Primary Roles: Sub-DPS, Debuff Support, Anti-Buff Specialist
• Key Strengths: Reliable multi-target dispel, massive bonus damage post-cleanse, AoE [Fear] for team enables, self-sustain via Insights.
• Notable Weaknesses: Low base ATK (around 120 at max), energy-hungry without proper Psychubes, minimal value in buff-less content.

In current endgame (Version 2.x+ as of 2026), he's a strong pick for Limbo farming, certain Rogue levels, and boss rushes with empowered adds, but skips general content clears. His value spikes with Eidolon 1+ for expanded dispel range.

In-Depth Skills Analysis

Horropedia's kit demands precise timing: Cleanse first, then capitalize on vulnerable states. All skills scale with Incantation Might, making IM substats crucial.

Normal Attack: Tremble

• Deals 100% Mental DMG to one enemy.
• Passive trigger: +15% Mental DMG if the target has any [Negative Status] (stacks multiplicatively with team buffs).
• Use sparingly as filler; prioritize skills.

Skill 1: Logic Dictates

• Rank 1: 200% Mental DMG to 1 enemy.
• Rank 2: 250% Mental DMG + Dispels 1 [Status Up] or [Positive Status] from target.
• Rank 3: 450% Mental DMG + Dispels from all enemies (Insight I upgrades to include [Counter] on all foes).
• Usage: Opener in 90% of fights. R3 version acts as a pseudo-AoE cleanse, essential for survival.

Skill 2: Sideshow

• Rank 1: 160% Mental DMG (+60% bonus if target lacks [Stats Up]/[Positive Status]).
• Rank 2: 240% Mental DMG (+90% bonus).
• Rank 3: 400% Mental DMG (+150% bonus).

Usage: Core nuke post-dispel. Bonus activates reliably after your own cleanses, hitting 550% effective at R3.

Ultimate: Twin's Play (60 Energy)

• 300% Mental DMG to all enemies + Applies 1 stack [Fear] (Enemies take +25% Mental DMG; stacks -1 after damage trigger, lasts 2 turns).

Pro Tip: Hold for wave 2/3 transitions or after team debuffs for 30%+ global amps. Synergizes with Regulus's scaling.

Full Rotation Example (Single-target boss):

1. Logic Dictates R3 (cleanse all).
2. Sideshow R3 (bonus nuke).
3. Normal/Tremble filler.
4. Ultimate (spread Fear).
5. Repeat Sideshow → Logic. Cycle time: ~25s with good Speed tuning.

Insights: Effects, Materials, and Priority

Insights transform Horropedia from niche to reliable, adding bulk and scaling absent in his base kit.

Total Cost: 210k Sharpodonty, full Mineral material lineup. Upgrade Priority: II (bulk first) > III (DPS ramp) > I (last for utility).

Advanced Farming:

• Daily Hard clears: 9-13 → 10-17 → 12-20 rotation.
• Events double drops; stockpile via Dispatch missions.
• Alternatives: Use material converters for shortages (e.g., Bones → Terror).

​Elite Psychube Recommendations

Psychubes define Horropedia's output—prioritize Lv.60+ with IM/CDMG substats. Speed tuning to 180+ ensures turn advantage.

Signature Path: Blasphemer R1 > Hopscotch R0. Substats: Speed (160+) > IM (250%+) > Crit Rate/DMG (1:2 ratio). Avoid Reality Psychubes; they dilute Mental focus.

Advanced Team Compositions

Horropedia elevates Mental teams by enabling nukes via cleanse/[Fear]. Pair with debuff enablers and healers.
