I had a problem with the way Sacred Flame was written.
It states that as a cantrip, I can cast it for 1d8 radiant damage at 25 ft if the target fails a dex check.
However, it states damage increases when I cast it at a caster level of 5th (2d8), 10th (3d8), 15th?? (4d8), and 20th (5d8).
Currently, I'm 5th level and casting at 3rd level. Did Wizards, perhaps, mean to write level and not caster level?
If not, I don't think Mordenkainen himself would be considered a 20th level caster.
The rules only go to level 9 caster, which a player reaches at 20th level (Epic)
Clerics reach caster level (CL) 5 at level 9, and CL 10 at level 18. Using that progression, I can expect to hit 5d8 on Sacred Flame if I hit 36th level on my Cleric.
By then I imagine I would no longer be a cleric, but a god.
