Reroll Dice

I have a little problem with a game I will be hosting. The ruls are based on a d6, with 5s and 6s being successes. Skill Rolsl then work as (Attribute+Skilllevel)d6>5 and it counts the successes just fine. BUT there is one more rule: All 6es will be rerolled. But I just can't find what I need to add, that there is another automatic roll for 6es (and then again for 6es, etc.) What I am looking for is something like this: Player A rolls Swordplay, meaning he has 4 dice. He rolls a 4, a 1, a 6 and a 3. One Success, and that being a 6 he rolls again for another 6, which gets then reroleld for a 3. Makes a total of 2 succeses. Is that possible? I just can't find anything that works.

Well, there's always reading the instructions (I know, it's like asking for directions, guys hate to do it!): "Exploding" Dice

I did read that, but I just can't get it to work the way I want it to.Either it doesn't work at all or it counts the numbers together instead of only the successes. Maybe it gets more clear if I post a roll example here: /roll (@{Dexterity}+@{Pos. Modifikator}-@{Neg. Modifikator}+4)d6>5 Meaning he counts together the Dexterity level + a possible positive Modifier - a negative modifier + the skill level (here:4) and then rolls that number in dice. Then he coutns every 5 and 6 as a success. But I just don't get it how I need to put it that he rerolls the 6es and counts them into the number of successes automatically.

Try this: /roll {(@{Dexterity}+@{Pos. Modifikator}-@{Neg. Modifikator}+4)d6!}>5

Yes, that works. Superb! Thanks you two!
