Underworld Iron Construct
+2 Str
0 Con
+2 Int
-2 Dex

Underworld Iron Constructs are bulky and unwieldy, but good at the tasks they are designed for.

Construct Traits: Constructs are immune to disease, paralysis, poison, sleep, stun, Constructs are not subject to nonlethal damage, fatigue, exhaustion. Constructs are not at risk of death from massive damage.

Coal Powers Temporarily - As a full round action, can sacrifice a certain amount of gold worth of minerals to fuel the fires of the construct. Every 100GP used in this way provides a +1 Str for the day, up to +4, at which point the cost increases to 1000GP per point, up to +8.

Fear Effect - Can cast the Fear spell 1/day with a DC of 13 + Cha; the construct reveals its frightening, tentacular inner form, the true unspoken beast within that drives it in ways no mortal machine can move.
