Eiji Variant Mithral Golem (3.5e Monster)

''A huge yet slender shining suit of armor made of sparkling silver stands in the distance. It must be some kind of polished iron golem, yet before anyone can say anything it charges you in a blur of extraordinary speed!''

Crafted from the purest mithral which is magically transmuted from lesser metals, the mithral golem is a shock to anyone used to fighting the slow and plodding golems of others. Graced with unnatural swiftness, they attack in a blur and leave their opponents destroyed before they even know what hit them. They take on the appearances of unusually skintight suits of armor for a creature slightly too thin and tall to be human based, with long gangly limbs and bright glowing eyes. A mithral golem cannot speak or make any vocal noise, nor does it have any distinguishable odor. It is 16 feet tall, but moves with surprising speed and grace for its size. It weights about 6,000 lbs.

A mithral golem’s natural weapons are treated as epic for the purpose of overcoming damage reduction.

Combat
A mithral golem is straight forward in combat, attacking the biggest threat to its survival in the room or the closest person barring that. Typically they are under direct orders which take priority, though as golems they can be awfully literal minded.

Blurred Motion : Whenever a mithral golem moves at least 10 feet, it gains a 20% miss chance against all attacks for 1 round.

Greater Extraordinary Health : Unnaturally tough, a mithral golem uses d20s as its hit dice. A mithral golem always recieves maximum hit points per hit die.

Immunity to Magic : A mithral golem is immune to all magical and supernatural effects, except as follows. A slow spell negates its alacrity for 1d4 rounds, while a haste spell restores 1d6 hit points per level of the caster (maximum 10d6) or restores its alacrity, if previously negated by a slow spell. Multiple slow spells simply extend the duration of the effect.

Overwhelming Force : Mithral golems possess an incredible amount of strength, to the point where they can demolish supposedly "invincible" force effects. A mithral golem may sunder any force effect such as wall of force or forcecage with Strength check, DC equal to 10 + the caster level of the effect, or by damaging it with attacks. Such force effects possess 10 hit points per caster level for the purpose of this ability.

Quickness : A mithral golem is supernaturally quick. It can take an extra standard action or move action during its turn each round. It is also under the constant effects of haste, whose bonuses (including the extra attack on a full attack) are added in the stats above.

Rapid Blows : Whenever a mithral golem makes a full attack, on the next round the mithral golem gets an extra attack as a free action. This benefit is culmilative, gaining an extra attack each round it makes a full attack. If 1 round passes and it has not made a full attack the effect resets and starts from the beginning.

Sprint : Once per minute, a mithral golem can make a full-round action to run 10x its normal speed.

Whirlwind : As a standard action a mithral golem can make one attack against each creature in its reach at its full attack bonus, as if using the Whirlwind Attack feat.

Construction
A mithral golem’s body is sculpted from 8 1/2 tons of pure iron and is then polymorphed into mithral (using polymorph any object). A mithral golem costs 250,000 gold pieces to create, which includes 5,000 gp for the body. Assembling the body requires a successful Craft (armorsmithing) or Craft (weaponsmithing) check (DC 30). The creator must be 25th level, have the Craft Epic Magic Arms and Armor feat, and be able to cast arcane spells. Completing the ritual drains 5,000 XP from the creator and requires geas/quest, haste, and wish.
