Cities of Sundara: Moüd, available in 5E and Pathfinder versions, introduced a new player species, the Half-Dead, living creatures affected by necromantic taint and who have taken on some of the characteristics of the undead as a result. Here are two new Fifth Edition heritages for the Half-Dead.

Mummified

Mummies are feared for mummy rot, a curse and a disease that the undead creatures spread by their touch that is difficult to cure. Sometimes, those affected by the disease, but who are not killed by it and are treated, especially if they only just survived, suffer from a lasting effect, one that affects them, or perhaps just their descendants. Mummified have dry, parchment-like skin, sometimes marked by what look like patches of dry rot, and flesh that is wasted, leaving the skin shrunken onto the bones, though they are stronger than they might look. Mummified gain a +2 bonus to their Strength and Wisdom and a -2 to their Intelligence. Mummified are immune to mummy rot, but are still affected by other diseases, only having the normal half-dead bonus. They gain a +2 bonus on saving throws to resist curses. This alters ability score modifiers, and replaces Touch of the Grave.

Ghostouched

Ghostouched are those who have survived the corrupting touch of ghosts but have suffered consequences as a result. They look aged, older than they are, with white, thinning hair and prematurely wrinkled and blotched skin, though their physical age is the same and they age normally. Ghostouched have been weakened by their experiences and have -2 to their Constitution but their experience has left them immune to the frightened condition and to the effects of magical aging. They also have +2 Wisdom. This alters ability score modifiers, and replaces Touch of the Grave.
