Dome Keeper Beastmaster Catgoblin and Frenzy Tentacle Build

To succeed with the Beastmaster, Catgoblins, and Frenzy Tentacle in Dome Keeper, divide your run strictly between creature-driven hauling and active dome defense. Dig straight vertical shafts so Catgoblins can ferry mined ores to the surface automatically, freeing you to carve deeper paths before returning to operate the Frenzy Tentacle against incoming monster waves.

Excavation and Catgoblin Route Management

The Beastmaster shifts transport duties away from your keeper's inventory to biological companions. On expansive layouts like Huge Relic Hunt, long transit times will drain your defense clock unless you optimize movement paths early.

Dig Straight Vertical Shafts: Carve primary tunnels directly downward from the dome cellar. Catgoblins transport loose chunks most efficiently along unimpeded vertical conduits; horizontal detours cause them to get stuck or drop ore.
Leave Ore in Central Drop Points: Do not carry individual iron or water tiles back manually once Catgoblins are active. Break resource clusters completely, leave the debris in central junction corridors, and continue digging into new rock layers.
Respect Return Travel Time: The Beastmaster must personally operate the dome weapon station to fight off attacks. Leave your excavation zone earlier than standard keepers during the first three cycles until keeper movement speed upgrades are secured.

Once you penetrate deeper rock tiers, invest in companion carry capacity and leash range so your helpers can clear entire veins in a single cycle.

Frenzy Tentacle Upgrade Stages and Combat

The Frenzy Tentacle functions as a momentum-based melee defense that excels against tightly grouped targets. Rather than tracking individual enemies with continuous fire, use rapid whip strikes to cleave flying swarms and heavy ground units before they damage dome armor.

Upgrade Stage	Primary Focus	Defensive Role
Early Defense	Reach and Base Damage	Eliminates minor flyers and lone ground creepers in single strikes.
Mid-Game Ramp	Whip Speed and Frenzy Trigger	Cleaves clustered melee attackers to build attack cadence rapidly.
Late Defense	Heavy Impact and Multi-Target Cleave	Crushes armored behemoths and repels simultaneous dual-side spawns.

In combat, time your strikes proactively. Sweep upward to swat aerial monsters before they launch ranged projectiles, then drive the tentacle downward into ground units clustered at the dome base to initiate frenzy streaks.

Resource Priorities on Huge Relic Hunt Maps

Deep-map economies require disciplined spending to avoid falling behind on both digging speed and defensive firepower.

Iron Allocation

Spend your first 15 to 20 iron strictly on keeper flight mobility, basic Catgoblin hauling efficiency, and early tentacle damage. Avoid spending iron on non-essential base gadgets or minor structural repairs until your core mining routine is fully automated.

Water and Cobalt Management

Water powers advanced creature abilities and dome overcharge systems. Keep at least two water units in reserve to overcharge defenses during severe wave spikes. Reserve cobalt exclusively for emergency dome health restoration; burning cobalt on early, minor damage leaves your dome vulnerable to late-game elite swarms.

Mid-to-Late Game Relic Retrieval

When searching lower strata for relic components, monitor the preparation timer closely and stop digging once the meter reaches the halfway mark. Position Catgoblins at intermediate shaft junctions to relay relic fragments upward in stages. Escort heavy core items directly to the dome hub while using fully upgraded Frenzy Tentacle sweeps to eliminate the final survival waves.
