Level: Spider 7

Components: V, S, M, DF

Casting Time: 1 round

Duration: 1 round/level (D)

Saving Throw: None

Spell Resistance: No

You imbue three small stones with magical power, causing them to twist and grow into large stone spiders.

This spell transforms three pebbles into stone constructs that resemble monstrous spiders. The constructs can be any size from Tiny to Huge as you decide, but all the constructs you create must be the same size. The constructs have the same statistics as monstrous spiders of the appropriate size, except as noted here.

Their natural armor bonus increases by 6.
They have damage reduction 10/magic.
Their poison has a Fortitude save DC of 10 + ½ your caster level + your Wis modifier. Initial and secondary damage is 1d3 points of Strength damage.

If the constructs can hear your commands, you can direct them not to attack, to attack particular enemies, or to perform other actions. Otherwise, they simply attack your enemies to the best of their ability.

Material Component: The three pebbles to be enchanted.
