The Skills plugin implements a full spellcasting system inspired by Ultima Online. Magic is organized into eight circles of increasing power. Casting any spell requires a spellbook, reagents, and mana — all governed by your Magery skill and the supporting INT stat.

​
The eight circles

Spells are grouped into circles numbered 1st through 8th. Higher circles deal more damage, provide stronger effects, and take longer to cast. Each circle also sets the base mana cost for every spell it contains.

​
Two-phase casting

Every spell goes through two sequential phases after you run /cast <spell>.
1

Pre-flight checks

The game verifies you have a spellbook in main hand or off-hand, possess all required reagents, and have enough mana. Any missing item cancels the cast before it begins — no resources are consumed.
2

CASTING phase

A blue boss bar labelled <Spell> Casting... appears and drains over the cast time. Moving more than 0.5 blocks or taking damage interrupts casting and consumes mana but not reagents.
3

TARGETING phase

The boss bar turns red: <Spell> Select Target! You have 5 seconds to left-click a target. Right-click or /cast cancel aborts with no resource cost. Hovering over an entity highlights it with a glow effect and the action bar shows the remaining time.
4

Resolution

The game rolls for cast success, consumes mana and reagents on both success and failure, and triggers the spell effect on a successful roll.
Self-targeting spells (Bless, Protection, Night Sight, Cure, Invisibility) skip the TARGETING phase and fire immediately after casting completes.

​
Cast time formula

cast_time = (2000 ms + circle × 500 ms) × (1 − magery_reduction)
magery_reduction = min(Magery / 100 × 0.3, 0.3)   // capped at 30%
At Magery 100 every spell is 30% faster to cast. The 5-second targeting window is not affected by Magery.

​
Cast success formula

base_success  = (Magery − circle × 10) + 50
int_bonus     = INT / 5
final_success = base_success + int_bonus   // clamped 5%–100%
Example — Magery 70, 5th-circle spell, INT 60:
  • Base success = (70 − 50) + 50 = 70%
  • INT bonus = 60 / 5 = 12%
  • Final success = 82%
Failing a cast consumes mana (and reagents if casting from the spellbook), but does not advance the spell effect.

​
Mana system

Mana is tracked separately from hunger and displayed on the scoreboard sidebar. It is never connected to the vanilla hunger bar.

Actual costbase_cost × (1 − INT / 200) — INT 100 gives 50% reduction

​
Mana recovery

Every 5 seconds you recover 0.5 × (1 + INT / 100) mana automatically.
INTRecovery per 5 s
00.5
500.75
1001.0
While sneaking and standing still, you recover additional mana every 0.5 s:
meditation_regen = 0.1 × (1 + Meditation / 100)
Each tick also gives a Meditation skill-gain attempt. Stop moving or stop sneaking to exit meditation.
  • Golden Apple — restores +5 mana in addition to its normal HP/absorption effects.
  • Enchanted Golden Apple — restores +10 mana.

​
Magic skills

Four skills govern all aspects of spellcasting. Each contributes to the INT stat, which in turn reduces mana costs and boosts cast success.

Resisting SpellsIncoming spell damage −(skill × 0.7)%; status-effect resistance +(skill × 0.8)%Receiving spell damage
Raising Magery, Evaluating Intelligence, Meditation, and Resisting Spells all increase INT, which further reduces mana costs and improves cast success — creating a compounding benefit for pure mage builds.

​
Spell categories

Spells fall into four broad roles.

Attack

Direct damage, area explosions, fire, lightning, and mind-affecting spells. Scale with Magery, Evaluating Intelligence, and the target’s Resisting Spells.

Healing & buff

Restore HP, remove status effects, and grant temporary combat bonuses. Duration scales with Magery.

Travel & utility

Teleport, mark locations on runes, open bidirectional gates, and generate food. Require runes for long-range travel.

Reagents

Each spell requires specific Minecraft items as catalysts. Consumed on every successful cast.

Spellbook

How to obtain a spellbook and learn spells.

Spell reference

Full stats for every spell across all eight circles.

Reagents

All reagent mappings and per-spell requirements.

Scrolls

Single-use spell items — no spellbook required.
