5e Epic Encounter box has younger variants

NO!!!!!!!!!!!!!!!!!!!

Question, would this be a viable reincarnation for a kobold? My party is wanting to fight pirates and they HAD 4 kobolds but one died, and I think it would be cool if they happened to stumble upon their reincarnated kobold whilst raiding pirates. Also, I'd need a young version of this because the kobold's death is pretty recent.

this sucks

A turtle that breathes in water? 

Car

Underrated ngl

Fizbans treasury of dragons has wyrmling, young and ancient varieties of the dragon turtle stat block

THATS REALY NEET!!!!!! im part of a dnd campaign dnd i asked a wixard to cast a spell to turn me into something powerfull and he turned me into the dragon turtle

Is it just me or are they a little weak for CR 17, especially for a dragon? compared for example to an adult red, yes they have some more hp and +1 to AC, but:

They have WAY lower damage output - while it may seem their dice # are higher, when accounting for legendary action tail attacks a red deals 107 per round, and the dragon turtle only a measly 58 (and also they have a +13 to hit as opposed to a +14, which makes this gap even larger)
They are much more vulnerable to spell effects - on top of having generally lower stats and no Cha saving throw proficiency, they don't get legendary resistances, meaning that all the worst spells (banishment, bane, phantasmal force, hold, dominate, polymorph, the list just goes on...) are pretty much guaranteed to work, whereas a red dragon pretty much shrugs them off
They have much lower speed and can't fly - one of a dragon's most valuable assets is its ability to take to the air and rain hell from above, or if it's starting to lose, just up and leave the fight. Being this slow means a dragon turtle is pretty much locked in with the melee fighters, and that it can't get out of spell range when necessary.

And that's all before touching on the fact it doesn't have blindsight, the downgrade from fire immunity to resistance, the worse action economy, lower breath DC, and the lack of any lair actions or frightful presence - are you really saying all of this is worth just 85 extra hit points?

I made a dragon turtle 1/60th of the entire world the players were on

and made it a short part of the lore

Check Fizban's Treasury of Dragons for young, wyrmling, and ancient dragon turtles.

Yay! now I know what sent my level three character to elysium
