How to Get Anti-Magic Mask in Anime Last Stand (Slime Patch)

A new update has been released for Anime Last Stand, introducing six new units, a new currency, and new portals. There’s a lot to do, but this guide will explain how to obtain the Anti-Magic Mask needed to Rimuru, aka evolve Slime (Majin) into its final evolution Slime (Devil Lord) in ALS.

Update: As of an ALS patch, the Anti-Magic Mask is also now a drop from the Slime Capsule, and the cost of the capsule has been reduced to 15 Shards.

First, I want to say this is not confirmed; this is me piecing together information from the Anime Last Stand Discord and YouTube on getting the Anti-Magic Mask.

There are two methods to get the Anti-Magic Mask in Anime Last Stand: one that is rumored but not confirmed and the other that is verified. The first method involves obtaining it as a potential drop from the Secret Slime Portal, otherwise known in-game as Tier 6 Abandoned Cathedral (Winter) Portal, with an unconfirmed 5% chance. The second method is through trading, but since it’s new and extremely rare, prepare to trade over the odds for it.

From what I’ve gathered, there isn’t much official information available regarding the drop rates. However, based on my observation, the Tier 6 Secret Portal can be obtained through the usual methods, and the drop rate is estimated to be around 0.1% upon completing Tier 5 of the Abandoned Cathedral (Winter) Portal.

The Anti-Magic Mask is said to have a 5% drop rate upon completing the Secret Portal. This means that there’s a small chance of obtaining an Anti-Magic Mask along with Slime, also known as Rimuru, who is a guaranteed 100% drop rate. However, it’s worth noting that the 5% chance is for the host, and the drop rate will be much lower if you are joining a Secret Slime Portal, estimated to be around 2.5%.
