The monk elemental ki strikes now do 1d6 for first rank 2d6 for second 2d10 for third and 2d20 for fourth.

I dont know how the earth strikes have changed since i dont have the +2 con tome on the test server that my charecter needed for the 3rd tier of earth strikes.

they no longer do extra dmg on a crit.

fists of light does 4d6 dmg to undead and and 1d50 dmg to undead on a natural 20.

fist of darkness does 2d10 to living creatures and 1d50 to living creatures on a natural 20.
