Tumacan is a grammatically conservative descendant of Old Bhadhagha, spoken near the Tumaca Mountains.

Phonology

/b d dʒ g/ are devoiced to (unaspirated) [p t c k] in all positions.
slender c, g, ch > /tʃ, dʒ, ʃ/ > retroflexes
/n, ʟ, ɾ/ distinguish between "fortis" or unlenited [n̪, ɫ, r] and "lenis" or lenited [ð̞̃, ʀ, z].
th, dh are [ħ, z] word-initially and become [h, z] word-finally.
/ʉ, ɵ/ are always fully back [uː, oː].

or just new consonants like tr dr > ts dz ks gz

grammatical mutation: just lenition - or no mutation at all?

Tumacan retains some Old Bhadhagha diphthongs - and has altered some of them.

Tumacan retains the Old Bhadhagha possessive suffixes.

tumaca could have b-prefixation (lenition or b-) only when there's a direct object

ní on the other hand doesnt trigger lenition (it didn't in OT)
