What is the snippet for Scaling damage dice on an attack (Similar to martial arts progression... )?

So my DM has allowed the Circle of Dragons for the druid but with some modifications.

Number one is scaling damage dice for the bite and claws.

Bite = d8, then d10 at level 6 then d12 at lv10. Claws are 2d4 to start then 2d6 at lv10.

Do note that I do NOT have the actual sub on my account but I believe I had been able to replicate it quite well.

For the lv3 Dragon Shape feature, I have enabled "Class Feature Options", 10- each one being its own dragon shape/color. You'd choose one and you'd turn into that dragon, gain the attacks & breath weapon, eventually the other abilities too but in later features.

The level 3 feature is pretty packed though - Once you 'activate' the desired form/color, you then have the designated breath weapon, bite AND claw attacks enabled (but since the claws are locked behind a lv6 requirement, it is hidden until then). 

To condense things, I have also had the breath weapon, claws and bite scale from this feature instead of adding it in the lv6 and lv10 sub feature spots (which tbh is what I think you're supposed to do to avoid duplicate attacks). The mechanics work. The numbers are all there are the appropriate levels

But with the bite for example, how do I have the snippet change from d8+wis to d10+wis to then d12+wis (like how the monk martial arts does)?

This is what I wrote:

```When you take the Attack action, you can use your dagger-like teeth to make an unarmed strike. Use {{modifier:str,wis}} for the attack and damage rolls. If you hit with it, you deal piercing damage equal to 1d8{{modifier:str,wis}}, instead of the bludgeoning damage normal for an unarmed strike.```

While I need to do the scaling damage for the breath weapon too, if you can also tell me how to scale the size of the breath that would be great too but not as important as scaling the damage dice (going from 15" cone all the way to 30' cone OR 30' line to a 60' line).

If you need more info like what snippets I had already written out or screenshots of how I built certain features let me know so I can get them for you.

Thanks!
