Why Rimuru is the Best Free-to-Play Unit in Anime Vanguards Update 6.5

Anime Vanguards Update 6.5 introduced several new units, but Rimuru—the Slime King—is quickly standing out as the top choice for free-to-play (F2P) players. Here’s a detailed breakdown of why Rimuru is such a powerful and cost-effective unit in this update, along with some tips on how to maximize his potential.

What Makes Rimuru Special?

Rimuru functions almost like a “Ragna 2.0” — a unit built for sustained damage output with a unique upgrade and buff synergy that makes him extremely efficient when used correctly. Here’s how:

• Multiple Placements with Shared Buffs:
  When you place multiple Rimurus on the battlefield, each one shares all buffs with the others. So if one Rimuru gets a damage boost, all others benefit equally. This creates a strong, unified damage front without needing separate buffs on each unit.
• Upgrade Cost Reduction:
  Each upgrade on one Rimuru reduces the upgrade cost on the other placed Rimurus by 8%. This means upgrading all four simultaneously becomes far cheaper than upgrading them individually.
• High Damage Output:
  Fully upgraded, one Rimuru can hit about 8,898 DPS. Multiply that by four placements, and you get roughly 35,592 total DPS—a solid damage output for a free unit.

How to Use Rimuru Efficiently

• Upgrade All Copies Together:
  Always upgrade Rimurus at the same time to maximize the upgrade cost reduction. This method lets you max out all four placements for under 100,000 currency, making him very affordable for F2P players.
• Targeted Damage with Great Sage:
  Rimuru’s Great Sage ability boosts damage by 40% against specific enemy types, letting you focus fire for faster enemy takedowns.

Is Rimuru Better Than Kogura?

Many expected Rimuru to outshine Kaga or be the go-to Vanguard unit because of his popularity. While Rimuru is a solid, usable unit—especially for those without Monarch—he’s not overwhelmingly powerful or meta-defining. He’s more of a reliable, accessible choice rather than a top-tier powerhouse.

Rimuru in Anime Vanguards Update 6.5 is an excellent F2P unit thanks to his damage potential and upgrade efficiency. While he has some weaknesses against debuffs and lacks support abilities, his ease of upgrading and solid DPS make him a valuable pick for players who want a strong free option. If you’re a free player looking for a unit to invest in, Rimuru deserves serious consideration.
