Whats wrong with this?

Ok, to start off, im a 20 W/Mo. When i try to farm, its pretty hard for me. I can solo Drakes pretty easily, but getting to them is the hard part, the poison from the skeleton archers just pwns me. When i try to do Scarab farming in Amnoon, they just destroy me. I was thinking if someone could help me organize/change my skills/attributes that i have right now, or just help me out with my build.

My attributes are:

Healing Prayers: 4
Strength: 11 (1 from helm)
Swordsmanship:12


My Skills are:

Mending
Healing Breeze
Sprint(Change to Ressurect if with a party/henchies)
Final Thrust
Sever Artery
Gash
Endure Pain
Hundred Blades

My Armor is the full Platemail armor set and a minor dmg reduction rune in the cuirass, and my shield(s) are Magmas shield 15 def(req 9 str) and shadow shield 15 def (req 8 str) with +4 def Vs. Skeletons (i use it for getting to drakes sometimes)My weapon is a 15-22 dmg Flamberge with 11% dmg while enchanted and enchantments last 14% longer

Any suggestions or tips on how to make my character be more suitable for farming will be greatly appreciated. Thanks in advance

Try to get Healing Hands. And I would also take one point off of swordsmanship and get the healing prayers up.

Hmmm, thnx ill do that. Anyone have any other suggestions?
