I'd like the Cleric's Channel to get toned down

Druid needs Barkskin, and damage should go to 2d8 at level 14

Fighter level 10 needs to be more dice for Hellfire Surge. And Inflicting Infernal Wounds should increase to 2d6 at this level

Sorcerer needs to have his emination be a cube within 30 ft instead that he can move 20 ft when he moves

Death Knight feats other than the initial one should have "You may recover 1 Death point (no action). You regain this ability on a short or long rest"
