Roll D8 make 1,2's into 3's

Just wondering , not seeing anything on it, but how would you roll some dice and turn any 1's and 2's into a 3. I know you can reroll 1's and 2's but the power doesn't have you reroll them, just if they are a 1 or 2 it turns them into a 3. Here is an example of the attack /me I attack [[d20+10]] vs AC [[2d8+3]] damage (need this so that if it rolls 1, or 2's it makes them into a 3. Please and thank you. ^_^

[[{1d8,d0+3}kh1]]. You need the "d0" there because the kh operator doesn't like mixing dice rolls and constants. Edit: You'll have to do each die separately, so you'd end up with [[{1d8,d0+3}kh1+{1d8,d0+3}kh1+3]].

You (your GM) can also make a rollable table: name weight 3 3 4 1 5 1 6 1 7 1 8 1 Then roll: /me I attack [[d20+10]] vs AC [[2t[myspeciald8]+3]] damage
Thank you both, that really helps.
If you're trying to macro brutal weapon damage, then I'd suggest [[2d6+7]] which would signify brutal 2.

TrollPlaya said: If you're trying to macro brutal weapon damage, then I'd suggest [[2d6+7]] which would signify brutal 2. That works as an approximation, but the probabilities are wrong. 1d8 with 1&2 replaced by 3 will be 3 37.5% of the time, compared to one of 4-8 12.5% of the time. 1d6+2 will be 3 16.67% of the time, the same as any other of 4-8.

I could do [[d8r1r2]] for a brutal 2 weapon, but i'm not, one of my players has a feat that turns any 1's and 2's into 3's not re-roll but 3's/

Right, 4e's brutal weapons keep rerolling the die, it doesn't set the die result to some minimum value. In the case of brutal, TrollPlaya is correct that you can subtract from the dice size and add the same amount to the roll, getting the same probability (ie, d8 brutal 2 is equivalent to d6+2). But this isn't the brutal mechanic.

Meldebius(Casey) , this should work for you: [[{1d8, 0d1+3}kh1 +{1d8, 0d1+3}kh1 +3]] damage Basically, you are telling it to roll a d8 and keep the highest of a d8 or a 3. It does this twice and then adds your damage bonus (+3). This turns 1's and 2's into 3's.
Oh wow, thank you!
