After many questions regrding the "Moat Trick" I have once decided to make some sort of mini guide with some nice pictures. Now it seems that that post has been deleted in the latest server crash/database self-delete thingy so I will now do it again. Hope it works for ya guys and gals.
Moat Trick Explained
The Moat Trick is actually quite simple. Trying to explain it in plain text is a little harder, so I made a series of screendumps to help me explain. Once you see it and try it out for a few times you'll get the hang od it, and you'll be picking Mephs pockets in record time with virtually no pain involved. I know some of you guys (or your mercs) can tank Meph, but this little mini-guide is for the less Ubergear characters who just can't tank him. Also there are things in it that are especially usefull to Pure Cold sorcs (Blizzard) regarding the Cold Immunes in Durance level 3.
First of all we need to be in Durance of Hate level 3. I'll leave the teleporting technique to you, since all it really is is teleporting as fast as you can through Durance level 2 to find the entrance to level 3. You'll need at least 63% of Faster Cast Rate to be "almost" safe. With less you'll find yourself dead in quite a few runs. This mini-guide starts when you enter Durance level 3.
When you enter Durance level 3, you immediately teleport to this point. It's the safest place, since Bremm Sparkfist is mostly parked somewhere else, but you need to be carefull though. From this location you can teleport slightly to the left untill you've got Bremms attention. You want him to follow you. You deffinately don't want him to be on the bridge because they'll be planting Hydra's around you when they're not properly taken care of.
When you've got Bremm's attention, try to lure him and his gang to the spot shown in this picture. The right side is generally the best way to go, because you don't want to rouse the gang of Dark Lords who generally reside in the left corner (they are Cold Immune). Jump over the bridge to park them, they'll not be a problem anymore, provided you don't rouse them again. You can of course kill them too, and Bremm and Gang can drop some nice items too, but the speedfreaks shoud leave them alone.
When you've succesfully parked Bremm and Gang on the right side, jump to the base of the platform before the portal to Hell, shown in this picture. This will make Meph charge in at your location. Don't let him go onto the platform, and if he does, try to get him slightly to the left of the platform. It'll speed things up, because you want Meph to be able to move a bit. Don't teleport further thatn this, because you're likely to rouse some Dark Lords in the back of the room. Static Meph when you have the chance, but there's really no big use for that (Blizz strooooong .... )
When you've got his attention, and Meph is slightly to the left of the platform, jump to this spot. Meph will try to follow you, but because he can't teleport or jump he's stuck at the little stairs. Just where we want him to be. Be sure not to rouse the last member of the Council because when he's Cold Immune it's the end of your Moat Trick story. Normally you won't see him (and he won't see you) but off course he just HAD to see me when I was making pictures.
At this point it's time to put on any MF gear you have that you weren't already wearing. At that time I was wearing a Vipermagi for the FCR, and I swapped it with Skullder's Ire. Just to show I made some pictures here and here to show you that we have absolutely no interference from any monsters that reside in Durance level 3. And when you're wearing the maximum of MF you have, proceed with killing Meph. Even with crappy gear Meph now is a walk in the park.
That's all there is folks.
Ah, just a sidenote, you see that I haven't used a merc at all. While I reccomend having a merc for general play, it is really not recommended to have one with you while applying the Moat Trick. Especially in the last stage the merc will try to get to Meph, get into the reach of his Orb Attack and be dead in no time. This is a waste of your good gold IMO, since your merc really doesn't help at all while doing Meph.
