Urgrosh

An urgrosh, also known as a spear-axe, is an exotic two-handed melee weapon.

Description
The urgrosh is much like the dwarven waraxe but with a longer haft, longer even than a greataxe but not so long as to be considered a pole arm. The gripping end of the haft is mounted with a spearhead. An average urgrosh costs 50gp and weighs 12lbs (5.5kg).

Use
Because of the two heads, the urgrosh can deal slashing or piercing damage at the choice of the wielder. The urgrosh is a double weapon that can be used for two-weapon fighting as long as it is wielded two-handed. If used one-handed, it is treated as either a shortspear or battleaxe. Dwarves favor this weapon because for them it is a martial weapon; for everyone else, it is exotic.
