Callie's tactics:<br/>Let people with HP take the hits.<br/>Try to snipe opponents from hiding (it's almost possible with her Hide bonus); when that no longer works, tumble into flanking position to maximize sneak attacks.<br/>Always target spellcasters first (arcane over divine) and try to steal spells; if she doesn't know what spells the caster has, default to stealing<em>scorching ray</em>or<em>cure moderate wounds</em>.<br/>Use any stolen spells that might be useful in combat as soon as she can get out of AoO range (using Tumble).  Spells that allow sneak attacks are especially good.
