Gnasher is an enchanted club +2. This weapon has a +2 bonus to THAC0 and damage, but the same speed factor as a normal club. Every time it hits, the weapons deals 1d6+2 points of damage, but also the victim will suffer 2 points of damage for 2 rounds. This item appears in Baldur's Gate II: Shadows of Amn, it can be found when a druid is killed in the Druid Grove area, which becomes accessible during the Animal Trouble in Trademeet side quest.
Makal of the Pine, a devious druid, carved this club and bonded it with the spirit of his wolverine companion. Like that tenacious creature, Gnasher is a dangerous weapon in the hands of a skilled user. When the club strikes, sharp splinters dig into the victim's flesh, causing extreme pain and even extra damage that continues for some time after the blow. Makal used the club successfully on several occasions, earning the anger of orc loggers threatening his forests.
