Help Making a Macro of d6 look like a d3 for Demon Gate and the Chaos System

So in the game Demon Gate the dice table which is used for attributes and skill checks and sometimes damage, the dice explode when you roll max, it is called Max Continuum. On the dice table the very first rank of the dice is a d3, but you normally in live games you roll a d6 with 1-2 representing a roll of 1, 3-4 representing a roll of 2, and a 5-6 representing a roll of 3. However if you roll a 6 it is a 3 but allows you to roll the d3 (d6) again. Anyway we can make a macro with this to implement into the dice table?

In roll20, just use a 1d3.  All the normal dice functions, such as exploding max dice, work fine with unusual dice. Or wait - the die only explodes on a 6, not explode on a 3??  Hmm.  let me think a bit on that case.  The short answer is use an API.  It might be possible to use a mathematical rounding, or a table to produce this result as well, and finally, you could use a button prompt to let the player roll the exploding die, which does give them a little more interaction when the good stuff happens.

You can use the round or ceil functions to divide the die by 2, and the !! to explode a die. This should do the trick: /roll ceil(1d6!!/2) If you want to see each individual roll, just use ! instead of !! /roll ceil(1d6!/2)

Thanks very much GiGs, that should do it! Thank you as well Aranador for responding.
