The list of options is more restrictive than the custom origin rules simply because it’s not the full list of skills, but the options are numerous and good enough that nearly every character will find a good option.
WIZARDS 5E CHARACTER BUILDER UPDATE
The update also increased the Tortle’s Claw damage to 1d6 and changes the Tortle’s original fixed skill proficiency, instead allowing you to choose from a small list of options.
The changes here were minor, replacing the Tortle’s Ability Score Increase trait with the new standard for ability scores, allowing players to assign either +2/+1 increases or three +1 increases. Most recently, Mordenkainen’s Monsters of the Multiverse re-published the Tortle. Tasha’s Cauldron of Everything introduced the option Customizing Your Origin rules, which gave us the second version and allowing players to reassign the Tortle’s ability score increases and their skill proficiency. The original was published in The Tortle Package and then reprinted in Explorer’s Guide to Wildemount.
There are effectively three versions of the Tortle. Portions of the materials used are property of Wizards of the Coast. RPGBOT is unofficial Fan Content permitted under the Fan Content Policy.
