Featured Challenge Guide

Ragna Dungeon Solo Guide
(Ace Build)

The ultimate method to solo farm the Featured Challenge for Rerolls and the Secret Unit Ragna using Spade (Ace).

The "Infinite Burn" Strategy

Why Ace + Astral is broken.

The Unit: Spade (Ace)

Spade is a Full AoE Hill Unit. This means he hits every single enemy in his range simultaneously. He also applies "Burn" damage over time.

The Trait: Astral

Astral is mandatory for the "Stacking" mechanic. It allows DOT (Damage Over Time) to stack infinitely on enemies.

Buffs: +20% Duration, -20% Cooldown, +50% Range

Why this works?

  • 1.Ace hits everyone (AoE).
  • 2.Astral makes burn stack.
  • 3.Enemies melt instantly because the burn damage ramps up to infinity before they can reach the base.

Equipment & Relics

Maximize DOT and Raw Damage.

Hat
Master Ninja Hat

"Every 5 attacks increase DOT damage by 20%". Essential for Ace.

Coat
Master Ninja Coat

+10% Fire Damage. Boosts Ace's base element damage.

Pants
Junior Ninja Pants

Raw Damage boost. Set bonus is currently bugged, so mixing sets is fine.

Tip: Put all your stat points into Damage. Range is already buffed by Astral, so raw damage is better for scaling burns.

Full Team Composition

Ace is the carry, but these units help.

1
Speedwagon (Farm)

Mandatory for economy. Get Fortune trait if possible.

2
Virtual Idol (Buff)

Buffs range/damage. Place next to Ace.

3
Sasuke / Luch (Stun)

Use for boss stun. Place, stun, sell, repeat (Luch tech).

4
Kenpachi (Debuff)

Increases enemy damage taken by 50%. Great for boss melting.

In-Game Steps

1

Early Game

Place Speedwagon immediately. Place Ace in the middle (where he covers most track). Upgrade Speedwagon to max ASAP.

2

Max Ace

Max upgrade Ace. Thanks to Astral, he will delete everything, even shielded enemies (1.8k shield mobs die instantly).

3

Boss Phase

When boss spawns, place Kenpachi near the track for the +50% Dmg Taken debuff. Use Sasuke/Luch to stun if needed. Ace will melt the boss in seconds.
