If a unit has Weaponmaster can it always equip gear without any cost?

No, a unit with Weaponmaster cannot always equip gear for free.

According to Rule 747.1.c and the associated FAQs, Weaponmaster functions as follows:

  • Cost Reduction: Weaponmaster allows you to pay the equipment's Equip cost reduced by [A] (1 power).
  • Not Free by Default: If an equipment has an Equip cost of 2 power, Weaponmaster reduces it to 1 power. It only becomes "free" (0 power) if the original Equip cost was exactly 1 power.
  • Non-Power Costs: If an equipment has a non-power cost (such as requiring a unit to be killed or another specific condition), those costs must still be paid in full. Weaponmaster only reduces the power portion of the cost.
  • No Cost: If an equipment has no Equip cost at all, Weaponmaster cannot be used to attach it, as there is no cost to pay or reduce (Rule 747.1.c.4).

In summary, Weaponmaster provides a discount, not an automatic "free" equip for every piece of gear.
