Do. Not. Want.
freyar said:Improved burrowing is good. It seemed to me, though, that the spines are not barbed, so whatever barbed defense we have should be kind of weak. Maybe even just an improved natural armor bonus. Yes on the Climb bonus. I'd agree on no saves vs cold environments and double damage on a failed save vs hot environment dangers.
Interesting. I'm not familiar enough with them to realize that the barbs aren't "spiky". Good to know. Since their natural armor is already pretty good, that might suffice.
+4 Climb bonus?
Temperature Regulation (Ex): An echidna's lukewarm blood and embedded spines allow it to better tolerate cold temperatures, but also makes it more vulnerable to heat. A giant echidna need not make a Fortitude save to avoid nonlethal damage in cold temperatures. However, it suffers a -4 penalty on Fortitude saves to avoid nonlethal damage in hot temperatures (see Heat Dangers in the DMG).
