Mjölnir
Mjölnir adds a physical hammer bound to a single owner, with seven combat skills, pathfinding recall, and orbital defense. It runs on Paper 1.21.11 and uses native Display entities, particles, and sounds. No resource pack, client mods, or external dependencies are required.
Hammer mechanics
The hammer follows gravity and drag, detects collisions along its flight path, and embeds on impact. Recall follows a 3D route through doorways and around obstacles within 32 blocks rather than teleporting.
Only players marked as worthy can wield or summon Mjölnir. Rejected attempts produce sound and movement effects without unprovoked damage or displacement.
Combat skills
| Skill | Description | Cooldown |
|---|---|---|
| World Anvil | A seismic field that damages and slows enemies within 10 blocks for 10 seconds. | 22s |
| Tornado | A channeled hammer swing that damages nearby enemies and pushes them outward for up to 8 seconds. | 14s |
| Skybreak | An instant lightning strike dealing 20 base damage to a visible enemy within 64 blocks. | 3s |
| Final Sentence | An ultimate attack that restrains a target, circles it, and descends from 50 blocks above with execution damage and a ground shockwave. | 120s |
| Storm Tether | A thrown strike that deals 8 base damage and pulls the target toward the owner as the hammer returns. | 15s |
| Ricochet Judgment | A ricochet between up to three hostile mobs, with damage decreasing after each hit. | 12s |
| Storm Anchor | A containment field that pulls hostile mobs toward the hammer for 6 seconds without direct damage. | 16s |
Skills support hostile mobs and eligible PvP opponents, respecting claims, creative and spectator modes, and friendly-fire rules. Ricochet Judgment and Storm Anchor are limited to hostile mobs.
Iron Escort
Iron Escort places the hammer in a moving defensive perimeter around its owner. It intercepts incoming projectiles, repels intruding entities along clear paths, and provides Regeneration, Absorption, nourishment, damage mitigation, and knockback resistance.
The defense remains active until recalled or interrupted, with a 20-second cooldown.
Controls and administration
Right Click throws the hammer, Q drops it, Shift + Q cycles skills, and Left Click casts the selected skill. F toggles Iron Escort, while holding Shift recalls the hammer or cancels an active channel. Ordinary items retain their vanilla controls.
Administrative commands cover hammer issuance, worthiness, and recovery. An atomic ledger tracks each hammer by UUID to prevent duplication across inventory transfers, disconnects, and server crashes.
Physics, recall, and skill settings are configurable. Block breaking is disabled by default; containers and protected areas are always preserved.
