Some of you might know me for the guide I wrote a couple months ago. I left GW before the release of Factions and recently came back. I had to adapt to the new skills/game changes, but now I think I'm ready to post another guide

A few weeks ago, Ricebox posted a guide for Scar Eater using a 13 health build (link). It sure is/was good, but required a no-Gaki spawn, which is somewhat uncommon. I decided to improve this, and I feel I have done so enough to call it my build. Props to whoever started using Sliver armor to solo as well

Before I begin with the gear/attribs/skills, I must say this is pretty hard to do and will take a lot of practice, but it is also very fast. Okay, enough talk, let's get going.
Attributes
Earth Magic: 10+2 = 12 Healing Prayers: 6+3 = 9 Protection Prayers: 8+3 = 11 Divine Favor: 8+3+1 = 12
Skills
Protective Spirit Healing Breeze Spirit Bond Spellbreaker {E} Sliver Armor Glyph of Elemental Power Mending Balthazar's Spirit
Gear
Weapon: 20% Enchanting one-handed weapon (Totem Axe works good)
Offhand: -50 Health Grim Cesta
You will *NEED* a 15 armor set, which you can get from Shing Jae Monastery or Ascalon. Take the set with +energy, you do not want +health or +armor bonuses on your armor.
The Run
Head outside Vasburg Armory to Eternal Grove (explorable), and cast Mending and Balthazar's Spirit on yourself (duh). Move forward until you spot the first group. Now, you have to know what is dangerous and what isn't. A Pain Hungry Gaki will cast Bloodsong which drains about 17 health per hit, while a Skill Hungry Gaki will cast Disenchantment, which removes one enchantment from you everytime you are struck by it. As soon as you trigger the Gakis's aggro, they will start spamming their spirits exactly where they are now, and follow you after they've casted everything. What you want to do is, if you spot a Gaki, make sure you aggro him and his group in a location where the spirits won't be in range to hit you later on. Here's a radar scan of your trajectory:
Gakis can spawn in groups 1 and 2 (one per group at most). They will never spawn in group 3. As you can see, if you aggro group 1 (which, let's pretend, contains a Gaki) at the location it is now on the radar, you will get struck by the spirit's attacks while going for group 3, after you've aggroed group 2. What you want to do is let the first group move in more (possibly down or halfway down the small hill), before aggroing:
On this scan, the white contour is where the first group is now, and the orange contour is approximately where you want it to be, prior to aggroing. When it's there, you're pretty much safe, as it (the Gaki's dangerous spirit!!) should be far enough to hit you. Even if you took a bloodsong hit you're fine, however Disenchantment could kill you. But hey, if you've done what I told you, everything will be fine =)
After you aggroed the first group, move on to the second one. Once both groups are running after you, you want PS (duh) and Spirit Bond up at all times now. Before aggroing the third group, recast your enchantments, and keep Healing Breeze up. Now, aggro the third group and go hug Scar Eater. Recast your three enchantments and from now on, make sure none of them goes down (i.e.: overcast everything). Cast Glyph of Elemental Power, followed with Sliver Armor. With three groups on you, 12 Earth Magic and the Glyph, he will die from one round of Sliver Armor every time. Keep yourself healed with the Divine Favor bonus by recasting your enchantments (PS/Breeze/SBond) over and over. As soon as Scar Eater dies, you gain a morale boost (you're now at 65 health, if I'm correct). In order to give you time to pick up your items, cast Sliver Armor, and keep overcasting your enchantments. Sliver Armor will make you block about 45% of attacks, giving you way enough time to pick up anything you want. When you're done, /resign or map travel

If you happened to die without being able to pick up your drops (which should only happen in a lag spike, because usually you should be fine), just switch armor pieces to get 13 or 33 health (13 = switch to -20 offhand, 33 = remove offhand), and go get your drops.
If Onis happen to spawn, make sure you cast Spellbreaker as soon as you see them pop up. Don't worry, they'll just help you kill Scar Eater faster

Make sure you never hit anything with your weapon because if you happen to strike a target with Tainted Flesh on, you'll get diseased (-4 pips of regen), which is too much to handle for you with 9 Healing Prayers.
I wish you all good luck with Scar Eater farming! I recorded myself doing this, hope you'll enjoy the video as well!
