Attachments and Grenades: Extra Utility
Attachments are a new form of Skill Gem available only to POE currency Crossbow users. These slot into your off-hand gear and act like active skills, such as grenades or traps. Unlike Quivers, they don't add stats but allow extra skills to be slotted-effectively giving Mercenaries more buttons and options than other classes.
Examples of attachment skills include:
Explosive Grenade Launcher
Flash Grenade Launcher
Fragmentation Rounds
Support Gems can modify these attachments, meaning your grenades can scale with area, damage, cooldowns, and more.

Incendiary Shot
Glacial Bolt

Explosive Grenade
These skills support various combinations between fire rate, status effects, and utility, giving Mercenaries a huge arsenal to tailor their build.
