Notes in redSolutions:
1) Manditory! Remove the extra +'s when using a Two Handed weapon. Make it a flat value for all weapon types.
Already Dev stated this PrC would be the favourite of THF specialists. Wait to see the other PrC's before claiming this is too powerful for 1 type of attacker
Pick one of the following:
2) Totally remove the 'additional chance to add Special effects' to Glancing Blow damage from 2 Handed weapons. Besides there are already two feats that allow something simliar to this: Cleave and Improved Cleave. (Power Cleave? Whats the second Cleave's name?!)
3) Allow 1 handed weapon wielding Kensia to make 'Glancing Blows' as well and keep the 'chance to add Special Effects' damage. A Feat should probably be required for this. This increases the S/B DPS while costing a feat (something most S/B fighters would gladly give to gain.)
You can not give 1 handers glancing blows. Using a 1 hand weapon is the only way you can 'turn off' glancing blows. The ability to turn off glancing blows is essential in some quests.
