Only a Priest of Fo can cast this spell
Morning fog is a spell which grants some protection from thorns. The protection is not permanent like a blessing; it is temporary. How good a protection one receives from the spell can be seen under "Settings > Spell Effects". This spell is great for grinding your channeling skill due to the very low favor cost.

Success:"You cast 'Morning fog' on yourself." "You now have protection from thorns and lava."
Better power recast: "You will now receive improved protection from thorns and lava."
Fail: [20:31:21] You fail to channel the 'Morning fog'.
