It's a PP from Shade, with stealth and concealment powers.What does the umbiri (sp?) swordmage paragon path do?
Spellscarred is a mutliclass feat so no Fighter/Swordmage/Spellscarred etc.
Ah the answer to the issue with Swordmage's low Will is not to Dump stat them. The class has a +2 Will so a 14 Wisdom or Charisma will get you a respectable 14 in Will defence. Then if you want more you will need to pick up items to sure it up. Further Intelligent Blademaster lets you essentially forget about Strength anyway giving you Con, Int and either Cha or Wis as your 3 stats to focus on, with Int the clear priority.
Swordmages are the "go to the trouble" type of defender, rather than the Fighter "the trouble is comming to me" style.
