Any idea how those work on Glancing Blows?

- sneak never triggers
- sneak triggers but on the base and the glancing damage is a % of the total base
- sneak triggers and applies to glancing
- sneak triggers and applies to glancing based on the % from your THF feats

Same w/ Monk PL ... does that +1 go on your base damage, before or after glancing reduction, etc.

Thanks in advance to someone who knows
