Gem tag
All skill gems have keywords listed in the first line of the mouseover description. In addition to dividing the skills into groups, keywords partly determine which support gems can support a certain skill.
Support Skill Keywords
While you can technically link any support gem to any skill gem, some combinations will have no effect. If a support gem contains one of the following keywords, the skill must have the keyword as well to be affected. Note that any skill with the Bow keyword counts as having Projectile.
- AoE: Concentrated Effect, Increased Area of Effect
- Attack: Additional Accuracy, Faster Attacks, Life Gain on Hit, Point Blank
- Duration: Increased Duration
- Melee: Melee Damage on Full Life, Melee Physical Damage,
- Minion: Minion Damage, Minion Life, Minion Speed
- Projectile: Fork, Greater Multiple Projectiles, Chain, Faster Projectiles, Iron Grip, Lesser Multiple Projectiles, Pierce, Point Blank, Ranged Attack Totem
- Spell: Faster Casting, Iron Will
For example, Freezing Pulse and Ethereal Knives get no benefit from being linked to Point Blank: although they are Projectiles, they are not Attacks.
