15% in les, 15% with miss+5 plus 8% from phoenix boots+7.
I think you need at least 25-30%: get phonx boots+6, 10% in les and 8% from miss+4, you will have a good 25%.
Also train your skills, it's easy to train from g7 to P.
Another suggest is to get some hp regeneration: 30% in helm and some % from crystal bracelet/amethyst necklace (or htn with stats), and some critical that may be in your hte,htb and weapon.I suggest a lion sword, it should cost only 7kk these days.Get some damage on it and fight

man you aren't noob, i wish you good luck on it
