Effects that apply to the attack-source do not directly apply to its attack-proxy. If an effect applies to an attack-source and modifies its properties, the modified properties of the object are inherited by the attack-proxy. Replacement effects that modify effects that apply to attacks do not modify effects that apply to the attack-source.

Example: Ironsong Determination has the text “Target weapon gets +1{p} and dominate until end of turn,” which applies to a weapon, and is inherited by any attack-proxies of that weapon. A weapon with 3{p} would be modified to have 4{p}, and its attack-proxies would also have 4{p}.

Example: Fog Down has the text “Non-attack action cards lose and can’t gain go again,” and Limpit, Hop-a-long is an non-attack action card. If Limpit, Hop-a-long the attack-source, its attack-proxy would not lose go again or be prevented from gaining go again, because Fog Down’s effect does not transitively apply to the attack-proxy, and the attack-proxy is neither a non-attack nor a card.

Example: Thrive has the text “If an attack would gain {p} this turn, instead it gains that much plus 1.” If a player resolves Thrive, attacks with a weapon, then plays an instant card that increases the {p} of the weapon, Thrive’s effect would not modify the increase in power to the attack because the effect modifies the weapon and does not specifically modify the attack-proxy of the weapon.
