Gems and runewords

24 gems · 5 tiers · 18 runewords

Beta 0.7.2

Gems go into the sockets of your gear: each gives a different bonus in a weapon, an armor piece or jewelry, grows with its tier and counts for half once socketed. The right gems in the right order make a runeword.

Gems

What one socketed gem adds, already halved; the gem's own listed bonus is twice this. Weapon covers weapons and offhands, jewelry covers necklaces, rings, earrings and bracelets, and armor every other slot:

Most gems give their full bonus in one item type (marked Best) and 60% of it, rounded, in the other two. Values are shown the way the hero sheet counts them (Health ×10, Regen ×1.5, Absorption ×5); halving can leave a half point.

Elemental gems

Garnet, Aquamarine, Citrine and Onyx give elemental damage in weapons and jewelry, and a large resistance in armor. In a biome with an element, half of the gems that drop are that element's gem:

Socketed value of one T1 gem.

Runewords

A runeword applies when every socket of the item is filled, the item has exactly as many sockets as the runeword has gems, it is of the runeword's type (weapon, armor or jewelry), and the gems are the right kinds, in the right order:

The bonus is multiplied by the tier bonus of the lowest-tier gem in it, then halved like gem stats. "Fits" lists the slots and rarities whose socket count matches.

Tiers and drops

TierBonusChest item levelSells for
T1 ★×11 to 1910 gold
T2 ★★×220 to 3930 gold
T3 ★★★×440 to 5980 gold
T4 ★★★★×760 to 79200 gold
T5 ★★★★★×1280 and above480 gold

The tier is 1 + floor(item level / 20) from the chest's item level before it snaps to a band, capped at T5. The game shows it as stars after the name.

Getting and spending gems

ChestsA gem is 10% of what any chest holds: one of the 24 kinds at random, except in an elemental biome (see elemental gems). Until a hero reaches level 12, the level of the Socket station, chests give a material instead of a gem.
Transmute8 identical gems make 1 of the next tier. 8 gems of one tier in any mix also make one a tier up; each kind's chance is its share of the 8.
SalvagePays the sell value above.

How socketing works

  1. 1
    Open the Socket stationHero level 12, 2,000 gold.
  2. 2
    Set gems Every new item already has all its sockets open; how many depends on slot and rarity (sockets by slot). Any gem fits any socket, and setting it uses it up.
  3. 3
    Taking a gem out destroys itNothing is refunded.

Each gem uses its bonus for the item's type. The item's gem stats are added up and multiplied by 0.5, and enhancement does not raise them. Socketing into an equipped item is locked during a boss fight.
