Reverse: 1999 Sotheby Build — Best Psychubes, Resonate & Team Comps

Sotheby stands as one of Reverse: 1999's most enduring premium supports — a 6-star Plant Afflatus healer and Poison enabler whose kit scales heavily with Attack, granting her the rare distinction of being both a top-tier healer AND a legitimate damage contributor within Poison team compositions. With Ramona's Banner LIVE and closing tomorrow (July 2, 2026), Sotheby+Ramona Poison team synergy hits its peak optimization window — every Sotheby build decision this week compounds directly into current-cycle endgame clears. This is the complete Sotheby Build Guide covering kit mechanics, Psychubes, Resonate strategy, Insight priorities, Portrays scaling, and the team compositions that unlock her ceiling — including the Ramona-focused Poison archetype currently dominating community meta.

⭐ Why Sotheby Matters Right Now

Sotheby has been the premier Poison team enabler since her original debut, but recent balance refinements and the current Ramona banner cycle have pushed her value to a new peak. She's referenced as a core team member across multiple Poison team compositions — including as the healer/support pairing in our R1999 Ramona Build — but has lacked a dedicated build breakdown until now.

The current synergy window is unique:

🟢 Ramona banner LIVE (closes July 2, 2026) — Poison team meta at peak activity
🟢 Sotheby scales with Attack — same stat priority as Ramona, meaning shared farming synergy
🟢 Plant Afflatus coverage — completes the Plant DPS + Plant support dual coverage
🟢 Poison Genesis Damage — bypasses Reality DEF, exploits Ramona's Poison amplification
🟢 Current endgame content continues to reward Poison team execution across Mane's Bulletin, Bulletin Mane, and standard event stages

🌿 Sotheby Kit Breakdown

Afflatus: Plant
Rarity: 6-Star
Role: Healer / Poison Enabler / Support
Damage Type: Genesis (Poison-based)

Sotheby's gameplay loop is built around applying Poison stacks that trigger at the end of the round, healing teammates via Attack-scaling incantations, and enabling Poison-focused DPS characters to reach ceiling damage output. Her positioning as both healer AND damage contributor means she rarely feels like a "dead slot" in team compositions.

Core Gameplay Mechanics:

Poison Application: Sotheby's incantations apply Poison stacks that deal Genesis Damage at the end of each round
ATK-Scaling Heals: Her healing output scales directly with Attack stat — high ATK = more healing throughput
Ultimate Timing Priority: Cast Poison incantations FIRST, then Ultimate or allow teammates to attack — Poison damage doesn't trigger until round end
Dual Utility: Contributes both sustain and damage every round, unlike pure-healer alternatives
Ultimate Might Scaling: Kit does NOT scale with Crit or Penetration — different from most DPS builds

🎭 Best Psychubes for Sotheby

Tier 1 (6★ BiS):

That Inquisitive Deer — Consensus best-in-slot. Provides increased Healing Done AND high base Attack stats. Directly amplifies both of Sotheby's core value drivers

Tier 2 (6★ Strong Alternative):

Balance, Please — Excellent stats for sustain and survivability. Works well when your team already has ATK-focused DPS characters covering the damage ceiling

Tier 3 (5★ F2P Alternative):

Laughter and Laughter — Boosts healing and reduces incoming damage. Solid F2P option that keeps Sotheby functional without premium Psychube investment

Tier 4 (Free Options for New Arcanists):

Brave New World — Baseline 5★ option that provides adequate stats for early-game clears
Blasphemer of Night — Situational alternative depending on team composition needs

For F2P Arcanists, Laughter and Laughter enables functional Sotheby without premium investment. That Inquisitive Deer represents the ceiling — pull only if you plan to commit long-term to Sotheby as your primary Poison team healer.

🔬 Best Resonate Build

Sotheby's Resonate priorities differ significantly from standard DPS builds because her kit does NOT scale with Crit or Penetration. Focus entirely on Attack scaling and defensive stats.

Resonate Priority Order:

ATK% (primary) — Maximum offensive scaling for both heals and Poison damage
Flat Attack — Compounds with ATK% multiplicative scaling
HP% / Flat HP — Survivability layer for tanking hits while healing
DEF% / Flat DEF — Additional survivability, especially important for Reality-focused enemies
Healing Effectiveness — Where available, boosts sustain output

Resonate Nodes to AVOID:

❌ Crit Rate — Kit doesn't scale with Crit
❌ Crit Damage — Wasted stat point
❌ Penetration — Genesis damage bypasses DEF; Penetration is redundant
❌ Ultimate Might — Beyond baseline, additional Ultimate Might offers diminishing returns for this kit

Grid Strategy:

Fill Resonance grid with Attack nodes maximally
Excess slots dedicated to HP/DEF for tank durability
Don't over-invest in single-stat sub-optimizations — Sotheby's kit rewards raw ATK

📊 Stat Priorities

Endgame Target Stats:

Attack: Target 3,000+ ATK for premium clears; 2,500+ for functional endgame
HP: Target 8,000+ HP for sustained encounters
DEF: Target 300+ DEF for survivability
Healing Received (Party-wide): Not a Sotheby stat — for teammate consideration

Stat Priority Rationale:

Attack scaling: Both healing AND Poison damage compound with ATK, making it the single most valuable stat
HP survivability: Sotheby often takes hits while healing; can't heal if she's dead
DEF layer: Reality DEF against physical hits, less critical against Genesis-heavy enemies

🧠 Insight & Skill Priority

Insight Priority Order:

Insight I (Skill 1 unlock) — Base healing incantation, priority target
Insight II (Skill 2 + Ultimate access) — Ultimate unlocks and Poison amplification tools
Insight III (Full kit unlock) — Maximum kit potential; recommended for endgame commitment

Incantation Level Priorities:

Poison Application Incantation: Max first — highest damage contribution per round
Healing Incantation: Max second — sustains team through boss encounters
Ultimate: Max third — biggest single-round burst window
Basic Attack: Lowest priority; only reach when other levels are maxed

🎰 Portrays Ranking (Duplicates)

Sotheby's Portrays value distribution:

Portray 1 (P1) — Meaningful quality-of-life; typically improves resource efficiency or Ultimate cost
Portray 2 (P2) — Significant power spike, especially for Poison damage scaling
Portray 3 (P3) — Notable ceiling raise; recommended target for Trinity of Poison Team commits
Portray 4 (P4) — Marginal gains, primarily for whales
Portray 5 (P5) — Sub-optimal — Rarely worth pulling for; investment better spent on other supports

For most Arcanists, P0-P1 Sotheby is fully functional. P2 represents a meaningful power spike if you plan to commit her to premium Poison team clears. P3+ is whale territory.

👥 Best Sotheby Team Compositions

Team #1: Premium Poison Team with Ramona (Current Synergy Peak)

Ramona (Main DPS — Poison archetype carry)
Sotheby (Healer + Poison enabler)
Bkornblume (Debuffer — Reality DEF down + Poison bonus damage trigger)
An-an Lee OR Tooth Fairy (Buffer — DMG amplification)

This is the current consensus best team leveraging Sotheby's peak synergy with Ramona. Both characters scale with Attack, both contribute Poison damage, and both benefit from Bkornblume's debuff support. For complete Ramona Build details including Psychube and Resonate optimization, see our Ramona Build Guide.

Team #2: Classic Poison Team with Jessica

Jessica (Main DPS — dedicated Poison team core, massive bonus damage vs Poisoned enemies)
Sotheby (Healer + Poison enabler)
Bkornblume (Debuffer)
An-an Lee OR Tooth Fairy (Buffer)

Classic Poison team archetype. Jessica remains the community-preferred pure Poison DPS if you're not committing to Ramona. For Arcanists building around Jessica specifically, Sotheby is non-negotiable — Jessica's kit demands Poison uptime that only Sotheby reliably provides.

Team #3: Sotheby as General-Use Healer

Sotheby (Universal Healer)
Any Main DPS (Not limited to Poison archetype)
Buffer/Debuffer
Flex slot

Following Sotheby's kit refinements, she now functions as a general-use healer across non-Poison teams. Her ATK-scaling heals maintain strong sustain output even without Poison synergy. Not her peak archetype, but flexible for accounts lacking dedicated Poison DPS options.

Team #4: Budget/F2P Composition

Sotheby (Healer)
Free 5-star DPS (Standard pool character)
Necrologist or Balloon Party (4-star support)
An-an Lee OR budget buffer

For pure F2P Arcanists, this composition provides functional clears with minimal investment. Sotheby's ATK-scaling utility helps compensate for lower DPS ceiling.

🤝 Sotheby + Ramona Synergy Deep Dive

Sotheby + Ramona synergy is the headline reason to build Sotheby during the current Ramona banner cycle. Here's exactly how the synergy works:

Shared ATK Scaling: Both characters scale primarily with Attack — same relic/Resonate priority overlap = shared farming efficiency
Poison Amplification Stack: Ramona's Poison-focused kit amplifies damage on Poisoned targets. Sotheby maintains Poison uptime = Ramona's kit stays at peak damage windows
Plant Afflatus Cohesion: Both operate within Plant-focused strategies
Ultimate Timing Coordination: Sotheby's Poison-first sequence sets up Ramona's damage windows
Complementary Sustain: Sotheby's healing keeps Ramona alive through boss burst phases

For Arcanists committing to the Poison archetype as their primary team identity, Sotheby is a mandatory investment — no substitute exists that provides equivalent healing + Poison enablement simultaneously.

📊 Sotheby vs Other Healers

Compared to Tuesday (Reality Healer)

Tuesday = Reality-focused sustain, works in non-Poison teams
Sotheby = Plant + Poison enabler, requires Poison team fit
Both are premium 6★ healers with different team archetype requirements
Sotheby scales with ATK; Tuesday has more traditional healer stat priorities

Compared to Necrologist (5★ Poison Healer)

Necrologist = Budget alternative for Poison teams
Sotheby = Premium version with significantly higher ceiling
Necrologist works as substitute when Sotheby is unavailable
Sotheby's kit refinements widened the gap between them

Compared to Isolde (Beast Genesis Healer)

Isolde = Beast Afflatus with different team archetype requirements
Sotheby = Plant Afflatus, direct Poison team alignment
Different Afflatus paths — coexist in different team builds

💡 Sotheby Build Tips

Cast Poison incantations BEFORE Ultimate — Poison damage triggers at round end, so Ultimate must apply before Poison activates for maximum stack effectiveness
Prioritize That Inquisitive Deer if you can pull it — Both healing AND ATK stats compound Sotheby's core value proposition
Don't slot Crit or Penetration nodes — Kit ignores both stats entirely; wasted Resonate investment
Max ATK Resonate before touching survivability — Damage scaling from ATK compounds heals AND Poison output
Position Sotheby's turn strategically — Poison-first sequence sets up team damage windows
Pair with Bkornblume for maximum Poison team output — Reality DEF down + Poison amplification stack multiplicatively
Insight III is meaningful investment — Unlocks Sotheby's ceiling; worth committing if she's your primary healer
P0 is fully functional — Don't feel pressured to chase Portrays unless whale-tier committed
Sotheby works outside Poison teams — Kit refinements allow general-use healer function, but peak value remains in Poison archetype
Coordinate with Ramona banner timing — Building Sotheby + Ramona simultaneously maximizes team synergy investment

Specifically:

🟢 Ramona banner LIVE = peak Poison team meta activity
🟢 Sotheby's Poison uptime maintains Ramona's damage windows
🟢 Shared ATK farming efficiency between Ramona and Sotheby
🟢 Current endgame cycles reward Poison team execution
