What are cheap piety and dom farming builds?

Hey guys, I want suggestions on Piety and Dominus farming builds that are cheap. Let's say 2ex or cheaper not including MF items. I want to test some builds to use for new leagues, so it needs to be cheap and effective. The build doesn't have to be able to map well, just be able to kill Piety and Dom fast and relatively safe. What are you guys ideas?

Also, before people suggest summoner, I currently have a lvl89 Summoner, and it's not actually cheap as I'm looking for if you want to be able to kill Dom quick and safely cause you need to buy/find at least Tabula and lvl 20 gems, which would cost more than 2ex for everything needed unless you want to level to around lvl 85 for lvl 20 gems before doing runs which isn't effective for a Piety/Dom farmer.

Any build is going to be more effective with level 20 gems than without them, so by that standard, all builds will be too expensive for you. As for testing builds for next league, it's kinda hard to say without knowing what will be changing between now and then. Odds are this will have a huge impact on which builds will be good then.

Right now though, fire skills in general seem to be very strong, so perhaps some sort of searing bond build or molten strike. Or just pick a class that you're interested in and look through the forum for that class. If you've been playing long enough to have a level 89 character, you should have some idea what you're interested in and there's tons of builds listed there, many of them designed to be cheap.

Yeah I mean, I have enough currency in Standard and Ambush I don't have to limit myself to 2ex to test a build. I was just giving myself a 2ex limit as a prepare for the worst situation in a new league and see what would still work if I didn't have much money. I just wanted ideas and suggestions really, things I could try out in standard and test.

Molten strike seems a good candidate, only used it at low levels but it was pretty strong. I've tested searing bond with a searing bond character I had, and even with a 5L searing touch with lvl 18 searing bond and increased burning, it's good for Piety runs, but it kills Dom too slow and very risky. Gotta Dual Flame totem guy too I'm gonna test once I get the gems leveled higher, see how that goes.

I'm also trying out Ziggyd's Glacial Cascade build..I'm only at level 39 so far, but definitely fun and effective so far. Also, Divinarius is probably the most expensive item needed for it.
