Sunwoo (Winter) Unit Guide - Anime Last Stand
Sunwoo (Winter) is a powerful AoE debuff unit with scaling damage over time that grows as you upgrade him. He shifts his status effect from Bleed to Flame and finally to Hemorrhage, making him stronger in longer fights. This unit also applies cripple effects to slow enemies and help control waves. He is an evolution of Sunwoo (Bloodlust) and requires several sacrifices and spirit shards to obtain. This guide covers costs, abilities, how to evolve him, reasons to use him, and common questions.

Overview

Sunwoo (Winter) is an Ultimate-tier unit added in the Solo Leveling update. He is designed to deliver strong area damage and lasting status effects that scale with upgrades. His attack patterns expand as he levels, changing from smaller AoE to larger cone and line patterns. He shines in long fights, raids, and maps with grouped enemies because of his hemorrhage damage over time and cripple utility. Investing in his evolution gives access to even higher tiers later on.

  • Total cost to fully upgrade: $234,560

Passives & Abilities

  • Status progression: Applies Bleed at early upgrades, scales into Flame, and later inflicts Hemorrhage for strong DoT effects.
  • Cripple effect: Applies a slowing or impairing effect on enemies to help control waves and protect allies.
  • Attack patterns: Starts with smaller AoE attacks and expands into larger AoE, cone, and line patterns at higher upgrades.
  • Signature interaction: Has an ability linked to summoned effects (commonly referred to by players as "Arise") that enhances his impact in longer fights.

How to Obtain

Sunwoo (Winter) is an evolution of Sunwoo (Bloodlust). You must first obtain the base Sunwoo unit, evolve it to the Bloodlust form, then complete the Winter evolution recipe. The evolution requires multiple sacrifices and spirit shards.

  • Required (evolve Bloodlust → Winter):
    • 1 x Sunwoo (Bloodlust)
    • 1 x Shadow Commander
    • 1 x Shadow Tanker
    • 30 x Common Spirit Shard
    • 15 x Rare Spirit Shard
    • 10 x Epic Spirit Shard
    • 6 x Legendary Spirit Shard
    • 2 x Shadow Essence
  • How to get base Sunwoo: farm raids, Hell City Act 6, or event drops depending on current spawn rules.

Release Date

Sunwoo (Winter) was added during the Solo Leveling update in May 2024 (around May 20–23, 2024).

Evolution Guide (Step-by-step)

  • Obtain the base Sunwoo by farming raid drops, Hell City, or event banners.
  • Evolve Sunwoo → Sunwoo (Bloodlust) following the Bloodlust recipe (requires shards and possible item drops).
  • Collect the Shadow Commander and Shadow Tanker units to use as sacrifices for the Winter evolution.
  • Farm spirit shards and Shadow Essence: prioritize events and higher difficulty bosses for Epic and Legendary shards.
  • Once you have Sunwoo (Bloodlust), both shadow units, and all required shards and essences, perform the evolve action to create Sunwoo (Winter). You will lose the sacrificed units.

Why Choose Sunwoo (Winter)?

  • Scaling DoT: The move from Bleed to Flame to Hemorrhage lets his damage grow into late game content.
  • Wave control: Cripple and AoE coverage help manage grouped enemies and protect your front line.
  • Versatile placement: Multiple AoE patterns make him useful on varied map layouts and choke points.
  • Future potential: He has a further evolution path leading to a Godly tier, so early investment remains relevant.
