Tortle

My name is not Oogway!

Tortles are a race of anthropomorphic turtles who live simple lives as peaceful farmers on the Savage Coast of Mystara, a region expanded as the mini-setting of Red Steel. Though inoffensive by nature, they will fight to defend their homes and they are naturally very good at tanking. Like their fellow Red-Steel introducees the Aranea, they have never managed to get any official update until 5e, in comparison to Rakasta (who became Catfolk in Races of the Wild) and Lupins (who got a Dragon Magazine article about them in issue #325). Their possible connection to the Teenage Mutant Ninja Turtles remains a mystery.

Tortles in Advanced Dungeons & Dragons have a maximum possible value of 18 for all stats; their minimum possible ability score for Strength and Constitution is 6, whilst all others can be as low as 3. When generating their stats, they suffer -2 Dexterity but gain +1 Constitution and +1 Wisdom. For classes, they are restricted to Fighter, Wizard (Mage, Abjurer, Conjurer, Diviner or Water Elementalist only), Cleric, Thief, Bard or Psionicist, being capable of attaining level 11, 9, 12, 9, 9 and 8 respectively, if you follow that stupid rule of race capping level limits. They can also be multiclassed as Fighter/Clerics. Tortle Thieves suffer a -5% penalty to their Move Silently and Hide in Shadows skills, a -20% penalty to their Climb Walls skill, and can't lift their body weight with just their arms alone.

Tortles are most notable for their powerful shells, which give them a base Armor Class of 3 -- remember, this was the edition of THAC0, so lower is better -- and they can drop it down to 1 by tucking into their shells, which also gives them +4 to all saving throws and immunity to gaze attacks until they come out. Of course, they're going to rely on this; their odd body shape makes it hard to get armor made for them and it really only provides a benefit if it's naturally superior to their shell's AC. Most tortles are going to be looking out for AC-boosting enchanted items like the old standard Ring of AC +1 or Amulet of AC +2, it's just more reliable that way.

They have infravision to a range of 60 feet, automatically proficient in swimming, and can hold their breath for 10 rounds automatically.

Weirdly, tortles die within a year of mating, so only those tortles who abstain from mating live to particularly great ages and children are mostly reared by their aunts and uncles, related or adoptive. Exactly why this is so, nobody frigging knows. This is not part of real world Testudines reproduction. 5e changed it so that instead tortles don't mate until in the final years of their lives - without any particular reason as to why this is the case. So, yeah, equally stupid.

For reasons that are probably obvious, tortles went fairly underdeveloped once Red Steel faded away. They haven't gone entirely forgotten, though.

D&D 3.5

In Dragon Magazine #315, 3.5 stats for tortles appeared as part of the brief look at the Mystara/Red Steel combined setting, with the following statblock:

-2 Dex, +2 Con, +2 Wis, -2 Cha

Base land speed 20 feet, swim speed 10 feet

Low light vision

+3 natural armor bonus

+8 racial bonus on Swim checks

Racial bonus feat: Endurance

Favored Class: Cleric

Level Adjustment: +0

5th Edition

Tortles then reappeared for D&D 5th edition as part of a special charity package tie-in module released to coincide with the release of Tomb of Annihilation through the DM's Guild website. They live off the Snout of Omgar in Chult in the Forgotten Realms now. This gave Tortles the following statblock:

+2 Str, +1 Wis

Medium

Base speed 30 feet

Claws: You can choose to inflict 1d4 + Str modifier slashing damage with your unarmed strikes.

Hold Breath: You can hold your breath for 1 hour.

Natural Armor: Your heavy shell gives you a base AC of 17, but its peculiar shape prevents you from using any armor, except shields.

Shell Defense: You can use an action to withdraw into your shell, gaining +4 AC and Advantage on Str and Con saving throws, at the cost of being Prone, having Speed 0, Disadvantage on Dex saving throws and the inability to take reactions until you exit your shell. Indeed, you can't use any action, save for a bonus action to emerge from your shell, so long as you are using Shell Defense.

Survival Instinct: Proficiency in the Survival skill.

If this version doesn't tickle your fancy, you can always try the one that Mr. Welch did for his 5e Mystara PHB:

+2 Strength, +1 Wisdom

Medium

Speed 25 feet

Tortle Shell: Your base AC is 14 + your Constitution modifier. You cannot use any type of armor, but you can still benefit from shields.

Personal Shelter: As a bonus action, you can withdraw into your shell, gaining +2 AC and Advantage on all saving throws, but being rendered Blind and functionally Incapacitated, with Speed dropping to 0 and you being unable to use Actions or Reactions, until you spend another bonus action to emerge.

Increased Lung Capacity: You can hold your breath for 2 hours.

Clumsy: You do not add your Dexterity modifier to your AC, ever.

Tough: You get +1 maximum HP at level 1, and a further +1 maximum HP each time you gain a level.
