Greetings!
I started playing SR back in 1990. After a few games I was in love! I GMd until around 1996 when life does what it does and I was forced to sell ALL of my books. And at the time I had everything related to SR that had ever been printed along with the DMZ. Sad day.

A couple of months ago a friend and I were talking about RPGs and SR came up and I started getting nostalgic. A week later he dropped off a beat up old copy of SR4 on my doorstep. The jerk.
Needless to say I am wanting to get back into the shadows in a bad way. I've been devouring the SR4 rule book, I'm building a huge story, planning on doing Food Fight 4.0 for practice/familiarization, I've got a group of gamers itching to run it, and I've ordered the 20th Anniversary book as well as the Toolkit for starters.
Today I started working on building characters. I was going to dig up my old SR1 characters and see if I could convert them but it's probably best to start fresh so I can learn/relearn the game.
With that being said I have an incredibly noobish question so go easy on me....
Improved Reflexes"This power increases the speed at which you react, just like wired reflexes. For each level, you receive +1 die to Reaction (this also affects Initiative) and 1 extra Initiative Pass. The maximum rating of Improved Reflexes is 3, and the increase cannot be combined with technological or other magical increases to Initiative."
My question.....When building an adapt who is using Improved Reflexes how does it affect initiative? I know I'm getting an extra D6 per level of Improved Reflexes but are those extra dice used during the initiative roll or am I actually adding 2 points to my reaction attribute?
It's kind of embarrassing going from hardcore daily SR GM to starting all over and having to ask for help on what is probably an obvious answer. So thanks for any clarification!
