Can you react to attaching equipment in Riftbound?

Ruling: You cannot react to the attach game action itself, but you can react to abilities that cause attachment (like Equip, Quickdraw, or Weaponmaster) before they resolve and attach the gear.

Sequence:

• Player activates an ability that attaches gear (e.g., Equip)
• The ability goes on the chain and targets are chosen
• Players can react to the ability on the chain
• When the ability resolves, the attach game action occurs (no reaction window here)

Nuances:

• Equip is an activated ability with a cost; attach is the game action that happens when Equip resolves
• Currently, all ways to attach gear in the game use abilities that can be reacted to before attachment occurs
• Rell's attack trigger is an exception where attach happens after equipment is played without using the chain in the way most people use it
