Vapen och rustning är undantag. Detta gäller för vardagliga och magiska vapen. Vapenstorlek bestämmer saker som skada, och det finns en massa regler för det :
Weapon Size: Every weapon has a size category. This designation indicates the size of the creature for which the weapon was designed.
A weapon's size category isn't the same as its size as an object. Instead, a weapon's size category is keyed to the size of the intended wielder. In general, a light weapon is an object two size categories smaller than the wielder, a one-handed weapon is an object one size category smaller than the wielder, and a two-handed weapon is an object of the same size category as the wielder.
Inappropriately Sized Weapons: A creature can't make optimum use of a weapon that isn't properly sized for it. A cumulative –2 penalty applies on attack rolls for each size category of difference between the size of its intended wielder and the size of its actual wielder. If the creature isn't proficient with the weapon, a –4 nonproficiency penalty also applies.
The measure of how much effort it takes to use a weapon (whether the weapon is designated as a light, one-handed, or two-handed weapon for a particular wielder) is altered by one step for each size category of difference between the wielder's size and the size of the creature for which the weapon was designed. For example, a Small creature would wield a Medium one-handed weapon as a two-handed weapon. If a weapon's designation would be changed to something other than light, one-handed, or two-handed by this alteration, the creature can't wield the weapon at all.
Armorn fungerar inte annorlunda baserat på storlek, men dess kostnader och vikter ändras. Se tabellen "Pansar för ovanliga varelser" på utrustningssidan .
Att dessa två har sina egna regler för dimensionering och inte nämns i regeln om storlekar av magiska objekt gör det klart att de inte automatiskt ändrar storlek. Dessutom kan regler för att skapa magiska vapen säga detta:
Weapons for Unusually Sized Creatures: The cost of weapons for creatures who are neither Small nor Medium varies (see Equipment). The cost of the masterwork quality and any magical enhancement remains the same.
När du gör magiska vapen eller rustning, måste du betala extrakostnaden för att göra baselementet för stora (eller större) varelser. När du gör något som en ring eller kappa behöver du inte oroa dig för det eftersom de ändrar storlek.
(Jag vet inte om Pathfinder har det, men 3,5 hade en "storlek" magisk vapen egenskap som skulle tillåta ett vapen att ändra storlek till sin wielder.)
