City of a Thousand Towers
CL 16th. 151,000 GP (equivalent to+8 weapon for DR purposes)
This +1 flaming burst brilliant energy longsword has a burnished copper hilt and burns with blue and white flame.
In the hands of a mythic wielder, the sword’s fire damage bypasses fire resistance and fire immunity. As a swift action, the wielder can expend one use of mythic power to enable the sword of inner fire to damage nonliving creatures (such as constructs and undead) for 1 round, though the sword still can’t damage inanimate objects.
A wielder of at least 3rd mythic tier can absorb the sword of inner fire into her body as a swift action, and call it back to hand with another swift action. While the sword is stored in this way, her eyes burn with orange flame and she gains a +5 deflection bonus to AC and a +2 luck bonus on all saving throws.
Brilliant Energy: A brilliant energy weapon has its significant portion transformed into light, although this does not modify the item’s weight. It always gives off light as a torch (20-foot radius). A brilliant energy weapon ignores nonliving matter.
Armor and shield bonuses to AC (including any enhancement bonuses to that armor) do not count against it because the weapon passes through armor. (Dexterity, def lection, dodge, natural armor, and other such bonuses still apply.) A brilliant energy weapon cannot harm undead, constructs, and objects. This property can only be applied to melee weapons, thrown weapons, and ammunition.
Flaming Burst: A f laming burst weapon functions as a f laming weapon that also explodes with f lame upon striking a successful critical hit. The fire does not harm the wielder. In addition to the extra fire damage from the f laming ability (see above), a f laming burst weapon deals an extra 1d10 points of fire damage on a successful critical hit. If the weapon’s critical multiplier is ×3, add an extra 2d10 points of fire damage instead, and if the multiplier is ×4, add an extra 3d10 points of fire damage.
Even if the flaming ability is not active, the weapon still deals its extra fire damage on a successful critical hit.
