I don't know what level Cyrion is, but he is a little tougher than the stronger monsters on the third level of the dungeon. I left and rescued Zandalor to get my teleporter stones before returning to do the lower levels of Iona's dungeon, and Cyrion took an extra couple of swings to kill.
If you are having trouble with level 3, then Cyrion would be difficult. There is a piece of chicken in front of the Cyrion's cave.... <span class='standouttext'>Spoiler : </span><span class='spoiler'>apparently you can toss chicken on the ground to distract Cyrion, giving you a couple second advantage.</span> (highlight the text to read)
