OK, so here's a good reason why I wanted to do this face-to-face. I'm aware you're well beyond this point in the character creation process, but I haven't been able to look at the forum till now. (And for that matter I would have been useless even if I'd seen it; I didn't get a refill on my codeine scrip until mid-afternoon today).
Current EDG Threshold is still 8, so going to add +4 to the roll to make it an 18.
You cannot do that. Specifically, the campaign rules PDF has the following listed (note the example in #2):
The Effect of Edge: Your Edge Threshold can voluntarily be reduced [by] -1 for your benefit in three ways:
1) Reroll a Lifepath roll (may keep spending Edge and rerolling)
2) Add +1 or -1 to a Lifepath roll result (ie, go from 11 to 10 or 12)
3) Enter a path that didn’t appear on your “Path Exit†(ie, go from Stage 3: Capellan Academy/Capellan War
College, to Stage 4: Tour of Duty: Federated Suns)
4) Remember, your EDG minimum is 2; you cannot go below that during character creation
You can use Edge to generate rerolls, or use a point of Edge to move a result up or down by 1...but you aren't supposed to be able to use 4 Edge on one roll to get a +4 to the roll.
With that said, I can totally see how you're reading it that way; both my rules text AND the example text in the MW3e rulebook (and the "errata-corrected" - ha - reprint) are unclear. All I can say is that in every example character I ever saw on the official forums, and every bit of character creation advice for MW3 I've ever seen, I've never seen
anybody advocate being able to stack the fixed roll modifiers like that during character creation. Moreover,
even if this is the correct reading of the MW3e rules, allowing it at this point would still be unfair to the other players who have already created PCs and who have no opportunity to address this problem (at least 2 people would have really, really preferred to be able to stack mods like that rather than multiple rerolls).
For example:
http://forums.cincybattletech.com/index.php?topic=727.0 You can see that Mike wanted to get a 17 result, and during his rerolls rolled a 15, then went back, spent 2 Edge rerolling (getting a 5 and a 16), and then a 3rd Edge to bump a 16 to the desired 17. If he could have simply spent 2 Edge to increase by +2, he could have spend 2 Edge instead of 3 and bumped the initial 15 result straight to a 17.
I'm sorry man, but in the interests of group even-handedness, I'm afraid I'm going to have you to repeat that
single step (if you so choose, you can even spend Edge on rerolls trying to get that 18 "back"). Note: as long as your eligibilities remain the same, the rolls from that point forward need not change, for example, as long as you still end up with a "Vehicle 6" trait, for example, the final roll of "Orion" still stands. Do remember that you still get points to buy Attributes and can take on Negative Traits in order to pay for things.
