Oskill

Equipping oskill items allows players and hirelings to use skills belonging to any class. Oskill level can only be increased by equipping multiple items supplying the same oskill, All Skills, Fire Skills or individual skill bonuses (normally class-specific). Equipping items with class-specific bonuses to an individual skill after an item with an oskill bonus to the same skill will result in the loss of that oskill, as will removing all items with the class-specific bonus after equipping the oskill item (either manually or by switching weapons in both cases). The oskill bonus can be restored by equipping the item supplying it again. This does not apply to a Barbarian switching weapons while equipping a [[D2 Rune Word weapon#Passion|Template:D2 Unique bold]] weapon (+1 Zeal oskill) either made in a scepter with +1-3 Zeal (Paladin Only), or with such a scepter in his other hand. When equipping an oskill item without any items with class-specific bonuses to the same skill, moving the cursor over an item in any vendor, stash or inventory screen which does supply a class-specific bonus to the same skill will also result in the loss of that oskill. Once again the oskill bonus can be restored by equipping the item supplying it again. [1] When the oskill belongs to the class or hireling equipping the item, the total oskill bonus is restricted to 3 regardless of the number of items equipped supplying the same oskill. However, class-specific bonuses to individual skill trees and class skill levels can increase oskill level as well for that class (but not for a hireling). Hirelings cannot use oskills that are active skills but they can use those that are passive skills. Oskills receive passive bonuses including synergy bonuses, but they do not apply synergy bonuses.
