The Martial Arts skill is a weapon skill that the Abbot class gains
As well as allowing you to equip and use Martial Art weapons (Hand art) this skill also determines what styles you can learn and therefore use in combat.
For a full list of the styles available for any weapon skill you can use the Library > Styles screen.
For a full list of the weapons that are tied to a specific skill you can use the Library > Items > Weapons screen.
To learn new styles visit the appropriate style trainer you can view the locations of style trainers via the Help > Manual > Realm Name guide page.
Combat Style Use
To use a combat style in combat you need three things:
To attack with a manually chosen combat style click the attack enemy button then choose which style you wish to use.
To attack with a manually chosen ranged combat style click the attack with ranged button then choose which style you wish to use.
You can also ready some styles using the Abilities > Styles screen then use the readied buttons instead of the manual buttons. The game will then pick the best style you have the stats to use that is on your ready list.
As the fight goes on your stamina will go down so the list of available styles will go down.
