SMPEnhanced

Features

⚔ Damage Caps

Cap the maximum damage a player actually receives (post-armor) from specific sources. A cap of 10 means no more than 5 hearts of final damage regardless of armor.

• Mace — caps smash attack damage only
• Spear — caps charge attack damage only
• Explosions — TNT, TNT minecarts, end crystals, beds, respawn anchors

⏱ Item Cooldowns

Custom cooldowns shown as the white shrinking overlay on the hotbar item.

• Mace — triggers on smash attacks; blocks all mace damage while active
• Spear Charge — triggers on charge hits; blocks charging while active
• Spear Lunge — action-bar cooldown; blocks the velocity boost even if you switch items mid-lunge
• Ender Pearl, Wind Charge, Chorus Fruit, Firework Rocket — hotbar cooldowns

Duration format: 10s, 1m 30s, 2h

👻 Happy Ghast Speed

Speed multiplier (1×–10×) for Happy Ghasts. 1× = vanilla speed. All loaded ghasts update immediately.

🛡 Item Destruction Protection

Prevent dropped items from being destroyed by explosions, fire, or lava.

🔮 Enchant Limits

Level caps for any enchantment on non-book items. Level 0 = enchant fully disabled. Enforced every second across full inventory, armor, and offhand — no workarounds possible.

🌍 Dimension Blocking

Block player access to the Nether and/or End. Covers portals, ender pearl throws, and chorus fruit teleports. Admin teleports are never blocked.

⚒ Limited Maces

Restrict how many maces exist at once. Shift-clicking the craft result respects the limit. Mace destruction/despawn decrements the count. Chat + title announcements (toggleable). Maces cannot be stored in ender chests.

💎 Limited Netherite

Per-item smithing limits with destruction tracking. Announces each craft and each destruction.

🔨 Disable Netherite Crafting

Block netherite smithing — globally or per item type.

🧪 Effect Limiter

Cap potion effects at a max level. Over-limit effects are replaced with the capped version at the same duration. Level 0 = effect removed on apply.

📦 Item Limiter

Per-material inventory caps. Excess dropped with full NBT preserved. 3-second pickup prevention. Trigger: onmove or onhit.

👁 Invis Kill Obfuscation

Kills by invisible players show garbled text in place of the killer's name.

🏪 Instant Restock

Villagers and Wandering Traders never run out of trades. Prices never increase from demand. Zombie-villager curing discounts are preserved.

🗺 Wandering Traders Persist

Wandering traders never despawn.

✨ XP Clumps

Merges nearby XP orbs and instantly delivers them to the closest player within 2 blocks. Great for PvP with mending armor.

🪨 Silk Spawners

Silk Touch breaks regular spawners and keeps the mob type. Trial spawners unaffected.

💀 Head Drop

Players drop their skinned head on death.

🧵 Inventory String

Admin-toggleable /string command (usable by all players) that fills empty inventory slots with string. Supports a cooldown.
