<p>I adorned my cloak with the 35% safefall adornment, then without watching i also adorned the cloak with in-combat health regen and then adorned again with in-combat power regen. The text said all went successful. When I went to look, only one adornment left... so i guess only one adornment, period?</p>

only one adornment.  Putting in another overwrites any that were there previously.
