Viessa
Overview
Viessa is a skill-first Descendant that clears packs by locking enemies into your AoE envelope, then converts uptime into damage through high-frequency casts and well-placed Blizzard windows.
Best For
Hard-mode mobbing with control/safety and a clean pivot into Blizzard-centric boss damage when you swap a small number of sustain modules for damage.
Best For
- Hard-mode mobbing (mid-range AoE)
- Solo farming with control and safety
- Event grinding where spawns cluster
- Colossus bossing (Blizzard pivot)
- Co-op lanes/holds where enemies funnel
Strengths & Weaknesses
Strengths
- High AoE throughput with repeatable casts
- Strong crowd control (freeze/lockdown) that reduces incoming pressure
- Scales extremely well with cooldown + crit + Chill multipliers
- Blizzard functions as both clear and boss pressure
- Safer farmer than pure speed builds due to control tools
Weaknesses
- Rotation feels bad if cooldown/cost isn't solved first
- Mid-range play demands positioning; not a full-screen tagger
- Skill-driven damage means reactors/modules matter more than weapon carry
- Boss damage can drop sharply if Blizzard uptime is interrupted

Alternatives
Increased HP
Swap in when Hard-mode chip damage is breaking your rotation; stability beats theoretical DPS for farming.
Dangerous Ambush
Bossing pivot swap: trade a sustain module (often MP Collector) for higher damage into priority targets.
Maximize Power
If your sustain is solved via components/reactor rolls, you can push more raw output at the cost of comfort.
Build Variants by Progression
Low-investment leveling setup: prioritize uptime so you can cast continuously, then add Chill scaling as capacity and drops improve.

Stat Priority & Reactor Guidance
Stat Priority
Primary
- • Skill Cooldown Reduction
- • Skill Cost Reduction / MP Efficiency
- • Chill Skill Power
- • Skill Power Modifier
Secondary
- • Skill Critical Hit Rate
- • Skill Critical Hit Damage
- • Skill Effect Range
Avoid
- ✗ Firearm ATK stacking as a primary plan
- ✗ Weapon crit/weakpoint investment as your main scaling axis
Reactor Guidance
Preferred Type:
Chill
Preferred Skill:
Fusion
Best Stats:
• Skill Cooldown
• Chill Skill Power Boost Ratio
• Fusion Skill Power Boost Ratio
• Additional Skill ATK when attacking Colossus (boss pivot)
Reactor tuning is a major lever for Viessa because uptime drives damage. Prioritize correct type/skill alignment and cooldown first; chase perfect substats after the loop feels continuous.
Rotation & Playstyle
Rotation
- 1.Open by establishing control space (lane slow/freeze tools)
- 2.Spam your fast Chill skill to clear packs and keep enemies inside your AoE envelope
- 3.Use control skills to lock clustered packs and reduce incoming pressure
- 4.Drop Blizzard on the densest clusters; on bosses, place Blizzard for core hit windows and re-cast on cooldown
Tips
- 💡 Mid-range discipline wins: keep enemies in your AoE, don't face-tank at point-blank.
- 💡 If you ever feel 'empty,' fix cooldown/cost before adding more damage mods.
- 💡 Your bossing pivot is usually 1–2 module swaps; don't rebuild the whole character to do bosses.
Farming Plan
Goals
- Kuiper shards (module leveling)
- Cooldown/cost modules and crit modules
- Chill/Fusion reactors with cooldown rolls
- General material throughput
Recommended Activities
- Hard-mode mobbing routes with dense spawns
- Wave/event content where spawns cluster
- Repeatable content where enemies funnel into lanes
- Colossus runs when targeting boss-condition reactor rolls
Priority Targets
- Dense spawn clusters (maximize Blizzard value)
- Activities that feed module progression (Kuiper + drops)
- Reactor farms when Chill/Fusion drops are active

Scaling Notes
Viessa's ceiling comes from solving cooldown/cost, then stacking Chill multipliers + crit so uptime stays continuous and Blizzard windows are frequent.
Team Synergy
Pairs well with tanks and groupers who hold enemies inside your mid-range AoE envelope; you provide deletion + control.
Known Issues
Without stable MP/cooldown, Viessa plays like burst-then-downtime; treat uptime as your first KPI.
