Combat profile
Shipped defaults for Minecraft 26.3 / NeoForge. Server base stats, wave scaling and ability settings can change these values. Existing server configurations may retain older costs and theme assignments.
Behavior
The mask searches for visible, living mobs bound to an active Nexus within 32 blocks. It flies to one host and attaches in front of its face, following the host’s look direction. Only one Devil Mask can occupy a host; another mask cannot be used as a host.
The host gains fire immunity, 50% more maximum health, 50% more movement and flying speed, and additional attack knockback. The health change preserves the host’s current health percentage. These bonuses do not stack. Killing or removing the mask removes its bonuses; killing the host sends the mask searching again.
In Versus, enemy Nexus armies take priority over friendly hosts. Attaching to an enemy permanently binds that mob to the mask’s own Nexus. Removing the mask ends the bonuses but does not undo the takeover. Without an eligible host, the mask moves toward the attackable Nexus and deals 2 damage every 20 ticks (one second) once close enough.
The mask itself is fireproof, takes no fall damage and ignores suffocation damage while attached to a living host. Defend by targeting the mask before it attaches, or destroy the attached mask to remove the host’s bonuses.
Spawning & configuration
Entity ID: invmod:devil_mask. Default themes: FLYING, NETHER, MIXED, RANDOM, RANDOMHELL. Use Themes and the entity configuration to change participation and costs.
The shipped wave spawn location is default. The spawn-location setting applies to Nexus waves; it does not change movement or damage immunity. There is no dedicated vanilla replacement for this mob.
Use its dedicated egg from the creative inventory, or /give @s invmod:devil_mask_spawn_egg with command permission. To summon the entity directly, use /summon invmod:devil_mask. See the Spawn Egg Reference. The egg shares its vanilla Silverfish family icon but spawns this separately registered mob.
See also the hostile face parasites Flying Eye (immobilization and Blindness) and Mini Squid (forced movement toward water). Their targeting and escape rules differ from the mask’s host bonuses.
Drops
No dedicated item loot table or custom death-drop reward is registered for Devil Mask in the inspected branch. It does not inherit the shared 25% Small Remnants roll of the older IM living-mob family.
