Universal Tower Defense Z Reaper City Raid Guide

Raid Overview

Reaper City Raid is Update 4.0's flagship endgame stage—a five-Act Bleach-themed raid with Boss Rush unlock after Act 5. It is harder than pre-4.0 raids and rewards Secret Flame Captain, the full Almighty Relic Set, Soul Reaper Badges, and evolution items for Cat Captain, Bloody Captain, and Ice Queen (White Haze).

Units with the Peroxide tag receive a 100% damage bonus inside all Reaper City stages. Meta picks include The Almighty King, Visionary (Unrivaled), and Moonless Sky for fastest Act clears and Boss Rush farming.

Act Progression and Drops

Clear Acts 1–4 sequentially to unlock Act 5 and the Boss Rush mode. Act 5 is the primary farm target for Flame Captain (pity on repeated clears) and Almighty relic Accessory, Top, and Bottom pieces. Act 4 drops the Frozen Blade evolution item for Ice Queen (White Haze)—5% per clear with pity at 15 attempts or 500 raid currency in the shop.

Act 3 can drop Black Cat Spirit for Cat Captain evolution (also sold for 600 Soul Reaper Badges). The built-in macro lets you AFK-farm Act 5 for relic pieces without babysitting every wave.

• Act 5 — Flame Captain drop, Almighty relic set pieces
• Act 4 — Frozen Blade for Ice Queen (White Haze) evolution
• Act 3 — Black Cat Spirit for Cat Captain evolution
• Boss Rush — post-Act 5 challenge with bonus drops
• Raid Shop — Ashen Sword, Stained Blade, Hollow Essence items

Flame Captain and Almighty Relic Set

Flame Captain (Genryusai) is a Secret-rarity DoT specialist from Act 5 and Boss Rush. Evolve to Flame Captain (Ember) for Scorched Domain—a 30-second active that grants +500% damage and summons 18 skeletons. Almighty Relic Set suits non-crit DPS: +30% buff gains on Accessory, +45% damage for 10s on DoT trigger with Top+Bottom, and +10% elemental damage on Necklace.

Pair Almighty on The Almighty or Ultimate Fused Warrior. Pair Heaven Piercer (separate set) on formation-based carries like Moonless Sky.

Farming Tips

Bring one Peroxide-tag carry, Virtual Idol for buffs, and a ground control unit for Act 5 leaks. Use the raid macro for overnight Almighty piece farming. Spend Soul Reaper Badges on evolution gating items (Ashen Sword, Stained Blade) before cosmetic shop picks.

Invite friends for faster clears—Reaper City scales well with coordinated teams, though solo is viable with Moonless Sky or The Almighty King at max investment.
