Okay...am warming to devadragon..aligns well with pseudodragon....I forgot to recalculate its CR...does it look strong enough for CR 1/2?
Let's see, considering a Cockatrice is CR 1/2… Well, frankly, no!
Other standard CR 1/2 are the Black Bear and Worg.
Why does it have all-encompassing damage resistance to Bludgeoning? Wouldn't it make more sense to give it "bludgeoning, piercing, and slashing from nonmagical attacks that aren’t [special substance]" like an Imp?
If we're looking to a Deva for inspiration, they have "Damage Resistances radiant; bludgeoning, piercing, and slashing from nonmagical attacks" so you could go for that I suppose.
What inspired the damage resistance to cold by the way? Is it self-heating!
I think I prefer it with the previous CON 13 (+1) to match an Imp or Pseudodragon. Giving it a +2 Con modifier is entering the field of the smaller true dragon's - i.e. a White Dragon Wyrmling has CON 14 (+2).
If it had similar damage resistances to an Imp then the previous Hit Points of 7 (2d4 + 2) would be appropriate for CR 1/2 as its resistance to nonmagical weapons and magic attacks would make it especially tough.
I'd also suggest giving it similar Condition Immunities to a Deva, which has:
Condition Immunities charmed, exhaustion, frightened
Hmm, what else?
Guess you could give it a Damage Vulnerability (maybe necrotic) but with so few HP it'd be extremely delicate to such attacks which argues against that.
Oh, how about giving it either full Telepathy or Limited Telepathy like a Pseudodragon? Telepathic abilities are common among outsiders like angels/devils etc in 5E. Devas have Telepathy after all.
Still thinking the damage output could be improved a bit. Maybe give them a bite and claws Multiattack instead of just a bite? Incidentally, older editions gave Pseudodragons the equivalent of 5E Multiattack as they could bite and sting in the same round.
An Imp's poisonous sting does 5.5 piercing plus 10.5 or 5.25 poison, which is about 13 average damage if the target saves 50% of the time. If we're aiming for CR 1/2 I'd eyeball the Devadragon should be doing about 7 average damage. Maybe a d4+2 bite attack plus a d4 claws attack?
Breath Weapon could do with some clarification too, but that'll have to wait.
