Wrestling
From UO Lost Lands Wiki
Wrestling
This skill is used anytime you engage combat unarmed. It functions the same as other combat skills such as Archery, Fencing, Mace Fighting Swordsmanship except without the need of wielding a weapon. It is useful on mages and spellcasters, due to it's defensive properties - players and monsters alike will miss more often while engaging in melee combat with you.
