Combat profile
Values below describe the Minecraft 26.3 / NeoForge defaults. Health is the configured adult wave baseline, not a promise of final HP. Per-entity stats, tier, size and wave scaling can change combat values; egg and command spawns are not a reliable test of wave overrides.
Behavior
Like the Speedy Zombie, it doubles movement: its Tier-3 movement value is 0.34 instead of the ordinary Brute’s 0.17. Its digging multiplier is 1× in Minecraft 26.3 / NeoForge; see tools and environment in timed mining. Soul fire does not damage it and clears its fire timer; ordinary fire is still dangerous. A Tier-3 Zombie converted by soul fire retains its tier and becomes this separately registered variant.
As a Tier-3 invader it resists knockback. A sprinting melee hit adds 3 damage and strong knockback, then ends the sprint. It attacks defenders and the Nexus and can mine obstacles. Equipment can change its combat role; weapons, armor and abilities remain configurable.
Spawning and waves
The current configured preset also uses cost 14; older saved entries keep their own cost until edited or regenerated.
Entity ID: invmod:speedy_zombie_brute. Its dedicated egg is invmod:speedy_zombie_brute_spawn_egg; it creates the Tier-3 variant directly.
/give @s invmod:speedy_zombie_brute_spawn_egg
/summon invmod:speedy_zombie_brute ~ ~ ~It is a wave-pool variant, not a guaranteed natural replacement of its base mob. There is no fixed first-wave unlock: selection depends on the theme, available budget, active mob settings and a valid spawn location. Standard adult pool cost: 14. RANDOM and RANDOMHELL use their own cost rules (5 for these non-boss mobs); baby options and variant rolls can have different purchase costs.
Shipped theme memberships: MIXED, RANDOM, RANDOMHELL, BRUTES, UNDEAD, ZOMBIES. These list defaults, not a guarantee of appearance. For built-in pool restrictions versus editable custom themes, see mob modes and Custom Themes.
Drops
Delegates to the vanilla Zombie loot table. Rotten flesh and conditional Zombie loot, including rare iron ingots, carrots or potatoes. Vanilla kill conditions, Looting and server loot changes apply. Tier 3 adds no guaranteed special item; carried equipment drops follow equipment rules.
