I assume "The Broken Spear" falls under the rules for a lasting effects in the FAQ during the phase in which it's used? Specifically I'm curious how it would work with something like Rusted Sword on a character that already has a military icon. If both of these weapons are on a character would the character keep a military icon when the Broken Spear is triggered?
The Broken Spear reads:
[Martell Attachment]
Weapon.
Any Phase: Kneel The Broken Spear to choose attached character. Until the end of the phase, that character either gains or loses a Military icon.
Rusted Sword reads:
[Neutral Attachment]
Item. Weapon.
Attached character gets +2 STR and gains an Military icon.
Any Phase: Kneel 1 influence to attach Rusted Sword from your hand to a character you control.
