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 largely determine which support gems and modifiers can modify a certain skill. The relationship is not strict, however.

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.

• Aura: Generosity
• AoE: Concentrated Effect, Increased Area of Effect
• Attack: Additional Accuracy, Cast on Melee Kill, Endurance Charge on Melee Stun Faster Attacks, Life Gain on Hit, Point Blank
• Chaos Void Manipulation
• Curse: Curse on Hit
• Duration: Increased Duration, Less Duration, Rapid Decay
• Melee: Endurance Charge on Melee Stun, Melee Damage on Full Life, Melee Physical Damage, Melee Splash, Multistrike
• Minion: Minion Damage, Minion Life, Minion Speed, Minion and Totem Elemental Resistance
• Movement: Minion Speed
• Projectile: Chain, Faster Projectiles, Fork, Greater Multiple Projectiles, Iron Grip, Lesser Multiple Projectiles, Pierce, Point Blank, Ranged Attack Totem, Slower Projectiles
• Spell: Cast on Crit, Cast on Death, Cast on Melee Kill, Cast when Damage Taken, Cast when Stunned, Controlled Destruction, Faster Casting, Iron Will, Spell Echo
• Trap: Multiple Traps

For example, Freezing Pulse and Ethereal Knives get no benefit from being linked to Point Blank: although they are Projectiles, they are not Attacks.
