The main gain from this skill is an increased chance to hit the target. It does not determine damage and speed, which are governed by strength and dexterity. A high Swordsmanship level also opens up new special moves with 70 for the first move of the specific weapon, and 90 for the second. Note that the Tactics skill is also needed.
Of note is that Lumberjacking increases the damage when using axes.
Training is the same for all weapon classes. First, buy training from a Warrior Guildmaster until reaching 30 points. After that, only real battle can help to improve. Therefore here the best battlegrounds for the varying skill levels.
|Skill Level||Enemies to battle|
|30 - 60||Skeletons, preferably 1-3 at a time, which can be found in any graveyard.|
|60 - 70||Lizardmen such as you'd find in the top level of Despise.|
|70 - 85||Ogres, again in Despise but at lowest level this time (avoid the Ogre Lords).|
|85 - 100||Earth Elementals found in Shame or Despise level 2.|
|100 - 110||Cyclopean Warriors found in Cyclops Valley in the Lost Lands and Despise level 3.|
|110 - 120||Troglodytes found in the Painted Caves.|
