All of the following are class features of Expert/Magic User.
Weapon and Armor Proficiency: A Expert/Magic User is proficient with all simple weapons, plus the longsword, rapier, sap, short sword, shortbow, and whip. Bards are also proficient with light armor A Expert/Magic User can cast spells while wearing light armor without incurring the normal arcane spell failure chance.
Archetype Spellcasting: Magic users gain Spell casting based on the chosen Archetype. Details can be found in the Archetype description.
Trick Casting: Starting at level 1 a Expert/Magic User can preform 1 trick from the list below. This increase to 2 times per day at level 4.
Ranged Legerdemain: An Expert/Magic User can use Disable Device and Sleight of Hand at a range of 30 feet. Working at a distance increases the normal skill check DC by 5, and an Expert/Magic User cannot take 10 on this check. Any object to be manipulated must weigh 5 pounds or less. She can only use this ability if she has at least 1 rank in the skill being used.
Impromptu Sneak Attack: An Expert/Magic User can declare one melee or ranged attack she makes to be a sneak attack (the target can be no more than 30 feet distant if the impromptu sneak attack is a ranged attack). The target of an impromptu sneak attack loses any Dexterity bonus to AC, but only against that attack. The power can be used against any target, but creatures that are not subject to critical hits take no extra damage (though they still lose any Dexterity bonus to AC against the attack).
Tricky Spells: an Expert/Magic can cast her spells without their somatic or verbal components, as if using the Still Spell and Silent Spell feats. Spells cast using this ability do not increase in spell level or casting time.
