What to know

  • Grass Excalibur is a special Excalibur variant tied to Grassite forging
  • It can only appear on Colossal-class swords
  • The drop chance is extremely low, even compared to normal Excalibur
  • Its damage is very weak, but its sell value is high

In The Forge, Grass Excalibur Sword sits firmly in the “ultra-rare collectible” category. If you’re chasing it, you’re doing so for prestige, completion, or profit—not performance. Here’s the full, up-to-date breakdown of how to get it and what to realistically expect once you do.

How to get Grass Excalibur when forging

Grass Excalibur does not drop from enemies, chests, or quests directly. It is a forging-only outcome that rolls during weapon creation, under very specific conditions.

The game first checks:

  • Weapon class (must be Colossal)
  • Ore type used (must include Grassite)
  • Whether the Excalibur roll succeeds

Only after those checks does the Grass variant have a chance to appear.

How to get Grass Excalibur Sword step by step

Step 1: Unlock and obtain Grassite ore

Grassite is not a standard mineable ore. It is tied to a secret quest found in the Spider Cave / Icy Cave area.

This quest usually involves:

  • A hidden NPC or trigger
  • An unusual interaction (often environmental)
  • A short objective such as retrieving something or activating a concealed element

Once completed, Grassite becomes obtainable for forging use.

Step 2: Reach World 3 and access The Peak forge

While the Grassite quest occurs earlier, you should forge the weapon at The Peak in World 3.

The Peak is preferred because:

  • It offers better trait rolls
  • High-end outcomes are more consistent
  • Late-game forging bonuses apply here

Forging elsewhere technically works, but you’re lowering your odds unnecessarily.

Step 3: Forge a Colossal Sword using Grassite

This is the most important restriction:

  • You must forge a Colossal-class sword
  • Grassite must be part of the recipe
  • Other weapon classes cannot roll Grass Excalibur
  • Requires a minimum of 50x Grassite for the forge

If the forge produces a non-Excalibur Colossal sword, the attempt is considered failed for this goal.

Step 4: Repeat forging until the roll succeeds

Normal Excalibur already sits at roughly 1 in 1,000 odds when forging Colossal swords.

Grass Excalibur is a special variant, so its probability is believed to be even lower.

Best pickaxes to farm Grassite efficiently

Since Grassite acquisition is tied to biome content and special nodes, mining speed and power matter.

Why players still chase Grass Excalibur

Despite weak stats, Grass Excalibur remains desirable because:

  • It is one of the rarest forging outcomes in the game
  • It sells for over $1,000 despite low damage
  • It functions as a prestige item for collectors
  • It proves mastery of late-game forging mechanics

Think of it as a trophy rather than a tool.

Tips to improve your chances

  • Always forge Colossal swords with Grassite
  • Stack Luck boosts and Miner/Luck potions before forging
  • Forge at The Peak whenever possible
  • Reset or server hop after failed Excalibur rolls
  • Don’t evaluate success by damage—evaluate by rarity
