TABLE OF CONTENTS

SSR Pool Overview

Sylus has 6 SSR memories available: 3 limited and 3 standard. His kit revolves around Dark-element damage with a unique HP-for-damage trade-off mechanic. Sylus can convert HP into bonus damage, then regenerate through his skill passives. This high-risk, high-reward playstyle makes him the premiere solo operative for Abyssal Chaos and tower content, where self-sufficiency is paramount.

Limited Banner SSRs

Twilight Oath (Dark)
Sylus's flagship limited SSR. Active skill: Sacrifice 20% current HP to deal 600% Dark damage. Passive: If this skill kills the target, regenerate 40% of max HP. If it doesn't, gain a 30% lifesteal buff for 8 seconds. R1 reduces HP cost to 15%. R3 increases base damage to 750%. The definitive Sylus memory — high risk, massive reward, and incredibly satisfying to use.
Element: Dark
Set: Shadow
Base ATK: 880
Tier: S+
Shadowbind (Dark)
Sylus's second limited SSR. Active skill: Summon shadow tendrils that root enemies for 3 seconds and deal 350% Dark damage. Passive: Rooted enemies take 25% increased Dark damage. R1 extends root duration to 4 seconds. R3 adds a chain effect — root spreads to nearby enemies. Excellent crowd control that enables Sylus's full combo rotation safely.
Element: Dark
Set: Shadow
Base ATK: 868
Tier: A+
Dark Harvest (Dark/Frost)
Sylus's latest limited SSR introducing dual-element synergy. Active skill: Inflict Dark-Frost damage over 4 seconds (4 ticks of 120% each). Passive: Each tick reduces the target's ATK by 5% for 6 seconds, stacking up to 4 times. R1 increases ticks to 6. R3 adds a Frostbite detonation on expiration. A unique debuff-focused SSR that enables off-meta support Sylus builds.
Element: Dark + Frost
Set: Permafrost
Base ATK: 885
Tier: A

Standard Pool SSRs

Night's Edge (Dark)
Standard pool SSR. Active skill: A quick Dark slash dealing 320% damage with 40% crit rate. Passive: Crits restore 5% of max HP. A reliable standard pool SSR that provides consistent self-sustain through crit healing. Good for F2P Sylus builds that lack the limited SSRs. The crit-heal synergy rewards building crit rate substats.
Element: Dark
Set: Shadow
Base ATK: 842
Tier: B+
Dark Mantle (Dark)
Standard pool SSR. Active skill: Gain a Dark shield that absorbs damage equal to 25% of max HP for 6 seconds. Passive: While shield holds, gain 20% ATK. A defensive-offensive hybrid that rewards aggressive play. The ATK buff while shielded encourages Sylus players to stay in the fight. Solid for content where survivability is a concern.
Element: Dark
Set: Shadow
Base ATK: 835
Tier: B
Blood Pact (Flame)
Standard pool SSR and Sylus's only non-Dark memory. Active skill: Deal 480% Flame damage, consuming 10% current HP for an additional 200% damage. Passive: Using this skill at below 30% HP heals for 20% max HP instead of costing HP. A high-variance memory that can either deal massive damage or save your life. Niche but memorable for clutch moments.
Element: Flame
Set: Solar
Base ATK: 828
Tier: C+

Acquisition Priority

Build your Sylus SSR collection in this priority order:

1
Twilight OathThe essential Sylus SSR. His entire playstyle revolves around HP management, and Twilight Oath is the centerpiece. Massive damage, self-heal, and lifesteal in one package.
2
ShadowbindProvides the CC that Sylus needs to land his full combos safely. Root then burst with Twilight Oath is the core Sylus rotation.
3
Dark HarvestStrong debuff focus. Good for team play and off-meta builds, but lower priority than the core two limited SSRs.
4
Standard Pool SSRsNight's Edge and Dark Mantle are functional. Blood Pact is a meme pick for style points.

Build Recommendations

For a standard Sylus DPS build, prioritize HP% substats on your protocores — Sylus's damage scales with both ATK and max HP on several of his key skills. Aim for 18,000+ max HP at level 80 for optimal Twilight Oath damage. Pair with a healer support for sustained content, though Sylus's self-healing is often sufficient for solo floors. Energy regen is less critical on Sylus than other operatives — his skills generate above-average energy per use.

Tip: Twilight Oath's HP cost can kill Sylus if used below 25% HP. Always keep a mental note of your HP threshold before pressing the skill. The lifesteal buff from a non-kill is excellent, but dying to your own skill is the most embarrassing way to wipe in Abyss. Get into the habit: check HP, then press Q.

Summary: Sylus's SSR pool delivers a unique HP-trade playstyle built around Dark-element burst damage and self-sustain. Twilight Oath is the essential must-pull that defines his identity. Shadowbind provides crucial crowd control, while Dark Harvest opens hybrid Frost-support options. His standard pool offers functional alternatives for budget builds. Prioritize HP% substats, master the HP management dance, and Sylus will carry you through content that would wipe any other operative.
