This page has the current set [β] of sound changes from Dele to Henaudute. There should be everything necessary here for those who want a Hena root that isn't already represented. (Well, everything except semantic drift...) They are roughly in chronological order. I may have left things out, so just let me know.
Aidan's reversal- Dele CVCVC root becomes CVCCV (reversal in protolang, analogized to all cases)
Banananana's apocope- Dele CVCV > CVC when both V are identical
Grassmann's Law)
These arrive out of compounding or inflection.
Labials and velars assimilate for voice and aspiration with a following dental stop. (e.g. pt, bd, phth, kt, gd, khth.)
A dental stop becomes [s] before another dental stop.
Any other combination of stops deletes the first stop.

N and N-stop combinations before S tend to disappear and lengthen the previous vowel.
RS goes to ῤῥ.
