Greatclub

A greatclub is a two-handed version of the club.

Description
A greatclub is bigger and heavier than a regular club and usually augmented with spikes, nails and/or bands of iron. An average greatclub costs 5gp and weighs 8lbs (3.6kg).

Use
The greatclub is classified as a two-handed martial weapon because the extra weight and the spikes make it a bit more difficult to wield without hurting yourself or your allies. The greatclub is not listed in the 1st or 2nd edition D&D.
