Sword Form (Ex): While in weapon form, a sword battleloth can use the aid another action each round as a standard action. Usually, it chooses to aid its wielder, bending and shifting its blade to slide past an opponent's guard or deflect attacks. If desired, the battleloth can instead make a single attack (+6 melee) against an opponent within 5 feet of the wielder, dealing 1d6+1 points of damage on a successful hit. This attack is in addition to any attacks the wielder makes with it. Otherwise, the sword battleloth functions as a +1 longsword.

Weapon Form: A battleloth can change to or from its weapon form as a standard action that does not provoke an attack of opportunity. While in its weapon form, a battleloth functions as a weapon of the appropriate type with the indicated enhancement bonus. It can use only those movement forms and attacks specifically noted in its weapon form description, but all of its special qualities apply to both its weapon and its humanoid forms. A battleloth can perceive the world around it and communicate normally while in weapon form. Since it lacks limbs, however, it cannot use spells that require material or somatic components.

In all other respects, the battleloth functions as a creature, not an object. It gains no hardness or additional hit points in weapon form, and any spells, attacks, or effects that specifically target it are resolved as if they had been used against the creature's humanoid form except that the battleloth benefits from a +2 size bonus to AC.

Outsider Traits: A battleloth has darkvision (60-foot range). It cannot be raised or resurrected.

Yugoloth Traits: A battleloth is immune to poison and acid. It has cold, electricity, and fire resistance 20. Battleloths can communicate telepathically with any creature within 100 feet that has a language.

Evil Subtype

A subtype usually applied only to outsiders native to the evil-aligned Outer Planes. Evil outsiders are also called fiends. Most creatures that have this subtype also have evil alignments; however, if their alignments change, they still retain the subtype. Any effect that depends on alignment affects a creature with this subtype as if the creature has an evil alignment, no matter what its alignment actually is. The creature also suffers effects according to its actual alignment. A creature with the evil subtype overcomes damage reduction as if its natural weapons and any weapons it wields were evil-aligned (see Damage Reduction).
