Grimforge
** Tools level up as you use them, swords evolve into demonic blades, and runes drop from monsters to socket into your gear. Built for PvP and factions servers, with balance tested in game.
Tools that grow with you
Pickaxes, axes, shovels, hoes and swords earn XP as you mine, farm and fight. Every level grants a modifier point to spend in the /tool menu:
| Modifier | Effect |
|---|---|
| Haste | +1 Efficiency per level |
| Lucky | +1 Fortune per level |
| Autosmelt | Smelts what you mine |
| Magnetic | Drops go straight to your inventory |
| Reinforced | Chance to skip durability loss |
| Experienced | More XP orbs from blocks and kills |
| Sharp | Bonus melee damage |
| Lifesteal | Heal a share of the damage you deal |
Progress lives on the item itself, so leveled gear survives deaths, trades and chests. That makes a max-level sword realy nice loot.
Swords that evolve
With the optional resource pack, swords change look as they level:
- Level 10: Tempered. A serrated, battle-worn blade.
- Level 15: Runed. Glowing runes etched into the fuller, a winged guard and set gems.
- Level 20: Infernal. A black blade with a molten edge, burning horns and drifting embers.
Every material glows its own color, so a glance tells you exactly what someone is carrying.
runes
Hostile mobs drop runes in three tiers: Magic, Rare and Legendary. Bosses always drop Rare or better. Swords and axes gain rune sockets at levels 5, 10 and 15.
| Rune | Effect |
|---|---|
| Ember | Sets your target on fire |
| Frost | Slows your target |
| Venom | Poisons your target |
| Storm | Lightning arcs to nearby enemies |
| Bleed | Damage over time |
| Crushing Blow | Bonus damage based on the target's current health |
| Soul Harvest | Regeneration after a kill |
| Retribution | Reflects part of the damage you take |
Built for PvP
Runes are fun but did not want them to be mandatory. Every number was tuned with pvp 1v1 on a r server: each Legendary rune is worth about one Sharpness level, and a full set of three about three.
- Runes only trigger on fully charged swings. Spam-clicking gets you nothing.
- Every rune has its own cooldown.
- Rune damage against players is reduced, and percentage damage is hard-capped.
- Effects are level I only, poison can't kill, and bleeds don't stack.
- Rune hits never grant invulnerability frames, so they never shield a target from your next hit.
Factions ready
Should work out of the box with FactionsUUID and SaberFactions:
- Runes never hit faction members, allies or truces, including Storm arcing into a crowd.
- Runes are off in safezones.
- Anti-farming: player-placed blocks, spawner mobs and creative mode give no XP. Placed-block tracking stays instant even in huge bases.
