Dwarven Double Waraxe
Waraxe, Dwarven Double: This hefty waraxe is similar to the common dwarven waraxe, but its recurved blade spans forward and back from its head like a deadly butterfly. A dwarven double waraxe grants a +1 bonus on all attack rolls after the first when using Cleave or Great Cleave.
Info on: Dwarven waraxe
Price 30 gp
A dwarven waraxe has a large, ornate head mounted on a thick handle, making it too large to use in one hand without special training; thus, it is an exotic weapon. A Medium character can use a dwarven waraxe two-handed as a martial weapon, or a Large creature can use it one-handed in the same way. A dwarf treats a dwarven waraxe as a martial weapon even when using it in one hand.
