Identify your team's primary weakness before spending upgrade materials on the That Time I Got Reincarnated as a Slime collaboration characters in Sword x Staff. If your roster lacks raw damage output against bosses, invest in Rimuru or Milim as main carries. If wave clear is slow, deploy Benimaru. If your team dies before clearing longer encounters, slot in Shuna to stabilize your defense.

Event Character Overview

Each collaboration character targets a distinct function in combat. Focus your upgrade investment on the unit that fills an open role in your existing lineup.

How to Select and Deploy Event Units

Primary Damage Anchors: Rimuru and Milim

Rimuru and Milim act as the primary offensive units in the collaboration lineup. Use Rimuru when you need a broad DPS option that fits general team structures. Use Milim when your progress is blocked by single-target boss encounters that require burst damage.

  • Gear Focus: Prioritize attack statistics and critical hit efficiency to maximize their damage scaling.
  • Investment Priority: These units require significant material investment to serve as primary carries, so commit resources to one anchor first before gearing secondary options.

Area-of-Effect Specialist: Benimaru

Benimaru specializes in wave management and multi-target combat scenarios. He handles high enemy density quickly, making him effective for mob-heavy dungeons where single-target units waste skill cycles on small targets.

  • Deployment Strategy: Pair Benimaru with lineups that support quick skill cycling to maintain continuous area damage.
  • Role Distinction: While Benimaru clears minion waves rapidly, do not rely on him as your primary single-target boss killer.

Support Utility: Shuna

Shuna provides defensive stabilization and utility buffs rather than raw damage. She enables high-damage carries to stay alive through prolonged fights and harder boss encounters.

  • Deployment Strategy: Slot Shuna into lineups that fail due to missing defensive layers or premature team wipes.
  • Role Distinction: Treat Shuna purely as a defensive support; do not replace dedicated offensive carries with her.

Resource Allocation Guidelines

  1. Avoid Even Resource Splitting: Concentrating materials into one or two primary event units yields faster progression than leveling all four units simultaneously.
  2. Preserve Roster Balance: Replacing a defensive support unit with an extra DPS character can lead to team wipes. Keep at least one defensive stabilizer if your team takes heavy damage.
  3. Verify Stat Compatibility: Check that your existing equipment aligns with the stat priorities of the collaboration unit you choose to replace permanent roster members.
