Aaaargh. Why do I suck at life?
1. I think that's just a typo. I've got the correct Dexterity bonus down on my Reflex save and init calculation.
2. It applies to Benjiro. He's by far the weakest element in the man-machine interface.
3. Yes, you have exactly caught my mistake. It has been fixed. And I am fully aware of the limits of Shapeshift- many powers are useful at low levels.
4. The Penetrating extra on a Mighty Strike must be bought for all of your Strength bonus, as well. The cost of the original power is 6 for the Strike, 6 for the Penetrating extra on the Strike, 4 for the Penetrating extra on the Strengh bonus, and 4 for the Power Feats, for a total cost of 20, or 17 for the purpose of Alternate Powers.
