You can turn off all powers you want. But yeah, centering is the way to go. 
Hmmm - it says powers that don't have an activation cost are always available. So if they can't be turned on, how can they be turned off?
If you've got a reference to being able to turn off intrinsic powers I'll be much obliged.
But the way I read the example of anyone who has Killing Hands (which doesn't add dice) taking the penalty on their Unarmed attacks, I have to assume that just because I have intrinsic powers like Critical Strike and Enhanced Accuracy than I am stuck with the -5 on my melee and ranged attacks. Which sucks, but I'll deal.
Like I said, if you've got a more clear reference then I'll owe you a soykaf.
And yeah, the Pulse spell is super vague.
Here is my 9 dice for general electronics (basically my tag eraser - ironic!) and my 16 dice for my commlink and medkit's computer.
resist for electronics:
9d6t5 1Does that mean I need a new tag eraser?
16d6t5: 7 [16d6t5=4, 3, 5, 6, 1, 4, 2, 2, 6, 1, 5, 6, 6, 2, 5, 1] (sorry, messed up the copy/paste on the bb code)
But I think maybe my commlink is okay???
Are we doing initiative yet?
Or just a few actions as they approach?
Right now I am doing what was in the IC - talking to Jackhammer, and ready to blow the wall as soon as Isaint takes any fire - which I sort of assume will be pretty much instantly.
Also readying weapon and switching to internal air.
Once I make the hole in the wall, well, the idea is that we try to get out and away as directed by our leader...I guess my subsequent actions depend on who actually does that.
I suppose everyone understands it's a good idea, but some will not want to leave for various perfectly valid RP reasons (Al can't leave Isaint behind without making a fairly hard roll, due to his totem rules).
This will lead to chaos, which will hurt us, but that's the hilarity that ensues when you mix pink mohawks with black trenchcoats!
So I suppose Al will either be yelling at people (as if he knows best - and yes, of course he does), or shooting at anyone coming in - whichever seems to become expedient first.
