1. The Mind Reading power states that "To use Mind Reading, make an opposed effect check against the result of the targetís Will check." If a character has Mind-Reading 10, does that put the DC to 20 (10 base + 10 ranks)? Is the opposed check then if the target of the power can roll a d20 + Will Defense and beat a DC 20?
My confusion is that I usually think of opposed checks as both sides need to roll (like Stealth vs. Perception).
2. I'm not sure I understand how "damage" works. Bear with me, I'm used to hit points and there isn't anything like that in MnM. Let me pose an example to see if I understand this right. A superhero with Str 10 goes to punch a villain (unarmed +10). He has to roll a d20 + 10 to beat 10 + the villain's Parry defense (let's say that's an 8 for a total of 18). So our superhero rolls a 12 and hits! So then the villain has to make a Toughness check (let's say his toughness is 9) vs. DC 25 (15 base + 10 Str). If the villain rolls a 6 (15 total), that is two degrees of failure: dazed and -1 to future checks.
If the villain in the above example had a force shield 11, impervious, he would take no damage from the attack (since the damage is less than the ranks of the force shield).
3. For a mental blast, do you just forgo the attack roll and then go right to the "damage" check? If it was Mental Blast 6, it would be the villain's Will vs. DC 21 (15 base + 6 ranks). Same damage rules apply based on the result.
Sorry for the very basic questions. I didn't think I understood damage, but just going through that example, I can see how the penalties will stack up pretty quickly and you'll be incapacitated soon enough if you get hit too much. Thanks in advance for your help!
