This is my awesome stealth mage Treasure hunter. I only do level 6 maps from the Miasmas. I always solo them; I haven't tried any of the lower level chests since ML came out, but I assume they would still be as easy as pie, though. You can actually do level 6 chests naked with just a few regs, but it's better to wear some low grade LMC/MR stuff.
I turned my character into an Elf for the awesome +20 mana.
115 str, 10 dex, 110 int (one of these days I'll use a better stat scroll)
720 Skill Cap, but you really only need 600 points
100 Cartography
100 Lockpicking
115 Magery (Can't afford 120 scroll)
100 Meditation
100 Hiding
85 Stealth (use rabbit form and it's 100)
100 Ninjitsu (not necessary; you can substitute any skill here)
The rest of the points aren't really used; I think they're in EI right now.
Equipment:
a small boat
12 lockpicks
2 blank runes
bag of sending
etherial Ridgeback
Spellbook: 14% LRC, 5% LMC, 5 mana
Rune Beetle Carapace, PBD blessed
20% LRC, 5% LMC, +5 mana hat, CBD blessed
Quiver of Infinity, Blessed
boomstick, insured (not really necessary, but the extra MR is great to have sometimes)
The rest of the suit is all low grade LRC, LMC and MR stuff that isn't worth insuring.
My current totals are:
MR 11, LMC 28%, LRC 100%, all resists below 30.
if you don't mind spending a little for insurance occasionally, you can use better equipment; I figure on dying about once per 2 or 3 chests, though, so I don't bother with using stuff good enough to insure. Besides, even with good equipment, you'll die when 2 Ancient Wyrms hit you.
Strategy:
1. place a boat if there's water close by. They can come in handy, especially on those small islands where some demon masquerading as a dev decided not to put any wandering healers.
2. bring 2 blank runes. Mark one right next to the chest, one offscreen; recall to the bank and drop these in the box, just in case. If the island is too small to mark one offscreen, move the boat far enough away that if you die and have to use help to get to town and get rezzed, when you recall off the boat key, you won't get insta-killed by anything.
3. Cast 2 EVs before digging up the chest
4. As soon as the chest pops up, hit the hiding key. Make sure it's a handy shortcut, because timing is everything and you don't want to be dead on a tiny island with 2 AWs and 2 bloods and no wandering healers; I hate using the help option.
5. Calmly walk offscreen; as soon as one EV dies, cast another one. Keep two EVs fighting until the original guardians are all dead. With decent MR equipment, you shouldn't have any problem with this.
6. If anything gets within targeting range, hide! Cast the EVs at the very corner of the screen, so that you don't get targeted, if possible.
7. Once the guardians are dead, unlock the chest and use telekinesis to blow the trap, then cast two more EVs.
8. Grab the bright green bag and the gold; use the Bag of Sending to send the gold to the bank. Most of the Marties aren't worth sending, but just in case you get a good one, you can send that, too.
9. Just keep casting EVs when they die; keep your finger on the hiding button. Every time you loot something, if a monster pops up, hit that button! FAST! The EVs can handle a blood ele, poison ele or titan, but not an Ancient Wyrm. If it's an AW that spawns, just hide, stealth to the corner of the screen while it's killing those EVs, then cast more EVs till it dies. If you have enough MR and LMC equipment on to keep casting them as fast as they die, it won't take long to kill it. Try for at least 12 MR, 40% LMC if possible. It isn't hard to do if you do a lot of chests. I forgot to change sets of armor when I went to Felucca to do some chests, and I lost everything when I got PK'd a few days ago, so I'm slowly building it back as I get stuff that's better.
10. Go back to Miasma, grab another map (there are usually a bunch of chests lying around there just waiting to be picked), rinse and repeat.
