|Syntax: stance arcana
The mystical arcana stance allows its practicer to fight in a trance-like
state. While in this state, all spell damage dealt to its user will be
reduced, and he can hurl his draconian spells with greater force, though at
the expense of a higher cost (1% of current mana).
Black magic spells are affected by the arcana stance in the same manner.
Additionally it reduces all spell damage taken by 1/3 and increases all spell
damage dealt, by an amount equal to 2/3 the caster's level (for one-round spells,
scaling with casting time). The focus bonus applies to this extra damage.
