How Do Support Gems Interact with Path of Exile 2 Currency Skills?
Support gems will only affect an active skill if:
The gem is compatible (e.g. Multistrike won’t work with a projectile spell).
It’s placed in a valid support slot connected to the skill.
You can inspect whether a support gem applies to a skill via its tooltip—if it modifies the skill, it will list how.
Support Tag Types:
Spell
Attack
Projectile
Minion
Totem / Trap / Mine
Elemental / Physical / Chaos
A support gem with the “Projectile” tag won’t work on a melee skill unless it converts into a projectile.
Modifier Effects from Support Gems
Support Gems can:
Add Damage (flat or percentage-based)
Change Damage Type (e.g., Elemental Conversion)
Change Skill Mechanics (e.g., Chain, Fork, Split)
Increase Cast/Attack Speed
Modify Resource Cost
Add Conditional Effects (e.g., bonus damage against chilled enemies)
These modifiers can stack, but there are often diminishing returns or limitations. For example, if you support a skill with multiple damage-enhancing gems, the mana cost may become excessive or path of exile 2 trade cooldowns may be longer.
