Shield of the Chonkster

Description:

A simple light wooden shield with two thick layers of snake skin stretched across it. The first glimmering outer layer of rainbow colored scales, and the second, an inner layer that seems to glow a dark jade green. The wood of the shield seems to be common wood itself, and the face is dotted with bits of fragmented bones. Each seemingly cold to the touch and filed to a sharpened point.
 

Item Effect:

This Light Spiked Wooden Shield is still a common version of itself, and follows rules as written for bonuses. Though see below for extra additions.
 

Ability

Shield Bash Attacks - Note anyone can do this, just adding for ease of use.

You can bash an opponent with a light shield, using it as an off-hand weapon. See Table: Weapons for the damage dealt by a shield bash. Used this way, a light shield is a martial bludgeoning weapon. For the purpose of penalties on attack rolls, treat a light shield as a light weapon. If you use your shield as a weapon, you lose its AC bonus until your next action (usually until the next round). An enhancement bonus on a shield does not improve the effectiveness of a shield bash made with it, but the shield can be made into a magic weapon in its own right.  

Shield Spikes

When added to your shield, these spikes turn it into a martial piercing weapon that increases the damage dealt by a shield bash as if the shield were designed for a creature one size category larger than you. You can’t put spikes on a buckler or a tower shield. Otherwise, attacking with a spiked shield is like making a shield bash attack.   An enhancement bonus on a spiked shield does not improve the effectiveness of a shield bash made with it, but a spiked shield can be made into a magic weapon in its own right.  

Materials

Rainbow Skin from Elder Flying Viper

This shield has the scales of an elder viper that has given its service to a crysmal, granting it a glimmering rainbow of scales. This grants the item DR 5/ Magic in which normal blows almost seem to bounce off of the scaled skin.
 

Adamantine Skin from Elder Flying Viper

This shield has scales of an elder viper that has drank from the liquid paradise and had its wish granted. Thus these scales grant +2 Enhancement bonus to the shield, and DR 5/ Tungston and adamantine, this item is also immune to Spells and Spell Like abilities. Which if actively Shielding another, then this immunity is applied prior to concealment rolls.

For each time this shield is used in a Shield Bash attack, the user upon success can add 1d8+6 Cold damage.
