A typical rough-skinned newt is up to six inches long (half of which is tail) and weighs less than an ounce.
Hmm, that size is in the right ballpark according to their
real life measurements, but it is much too small for a Tiny creature. The SRD Lizard is "perhaps a foot or two in length", not six inches like a rough-skinned newt.
I'm thinking we should downsize it to Diminutive and cut the Dex by 4 so the AC still matches - in my experience newts and salamanders are pretty slow compared to lizards, so Dex 15 is likely too much anyway.
Reducing the Hit Dice by 1 size category to 1/4 d8 would also match the "1-2 hps" of the original creature.
Also, apparently
if one bites you the contact can be enough for its "touch poison" to apply, so I fancy adding that to the attack line.
If we include the different Environment I suggested in my previous post, that'd make the following changes:
