Away from my books for a few more hours...
Q 51: What is the caster level of the Spriggan's spell-like abilities (Fiend Folio)?
Q 52: A Spriggan Swashbucker could qualify for Daring Outlaw all by himself, but what happens when he becomes large-sized? Would he then lose all his sneak attack?
Sub-question A: Assuming the above Spriggan would lose all his sneak attack, and wants to prevent that, what is the best way for him to gain the +2d6 sneak attack with the least impact to his BAB? I suppose a level of Warblade and two levels of fighter to get Cloak of Deception and Assassin's Stance without a BAB hit?
Edit: Found the caster-level on-line; CL 8. That means a Spriggan Fey 5/LA 2/Swashbuckler 9 (or something similar) could fight with Produce Flame, doing 2 full attack touch sneak attacks out of every 3 rounds.
Round 1: Invoke the Produce Flame and throw it at your target, then move into flanking position.
Round 2: Three touch attacks at BAB +11/+6/+1 (and add +5 dex mod to that), plus flanking +2, for 9d6+5 fire damage each hit.
Round 3: Repeat round 2.
Round 4: Touch attack once and 5-ft step away.
Round 5: Repeat steps 1-4.
Not bad. Sure, resistance to fire hinders it, but still not bad.
