I've done that achievement. My only five star gear at the time was a trinket, and my other trinket slot was empty. And I had nine health capsules left over when I finished it, too.

My recommendation would be to practice tier 3 in random gates (not just FSC/Vanaduke endlessly) until you're good enough that you can often get gold survivor without particularly trying for it (or perhaps rather, would have gotten gold survivor if you hadn't died in a danger room or third arena). If you can't do gold survivor, then you can't do dauntless delver anyway. There's no sense in spending two hours to get to tier 3 if you're going to predictably fail there, anyway.

After that, pick a gate with Snarbolax or Roarmulus Twins as the boss, as Jelly King and Vanaduke are too hard to reliably kill without dying. And pick a gate with relatively easy themes for the fifth and sixth strata. You'll probably want to avoid a fiend theme, and might want to avoid undead, shock, and/or fire, too. Other themes tend to be easier. (Incidentally, the undead part of an undead-themed stratum is easy; it oddly tends to throw in other, harder mobs that aren't undead.)

After that, start your own group in tier 1 and go. Avoid danger rooms from fourth stratum onward, and third arenas from fifth stratum onward. If a nasty level shows up in tier 3, such as Infernal Passage, then wait for it to rotate out. If a gate has a level in tier 3 that forces you to do Infernal Passage, Sinful Steps (1 or 2), or Ritual Road (1, 2, or 3), then you might want to just pick a different gate. Scarlet Fortress levels can be relatively difficult, too.

Save your early health capsules. When you start tier 3, you should have three tier 1 health capsules and three tier 2 health capsules saved up, as those may bail you out of a bad situation. Remedy capsules are good, too, so that you don't get killed indirectly by an untimely freeze, stun, shock, or whatever.

I did dauntless delver in a PUG, though a couple of people on my friends list did show up for part of the run. I don't think there is any real need to worry about who else is in your group until tier 3, or possibly Ironclaw Munitions Factory if you're doing a gate with that. If you can't carry a flagrantly bad group through tier 1, then you have no business trying for dauntless delver, anyway.

Did it weeks ago I just waited for an easy gate to spring up and breezed through it solo, took a long arse time though but never really had any danger my biggest scare was probably getting DC while waiting for a certain floor, was worried it would kill the achievement even if I got back on quickly but it was fine.

Is that the mineral one, because that's the only one I need too. I hate that you don't know how much you have deposited. I figure that I got to be close but I have no way of knowing.

I did this a while back, did every danger room and arena too :D It took just under 4 hours. Be sure to do it at a time when there are no reboots expected. I solo'd to Depth 23 then filled up the party to go to the Core just so I wouldn't be the only one with aggro.

I'd recommend trying it on the gate with no boss or the gate with Snarby to eliminate the chance of an "oops" in the boss level.

>.> why does everyone says it takes 3-4 hours o.o,

t1: run past all monsters to get into gates : maybe 3-5minutes each, 6 depths:30mins
t2:same
t:3 also same except areas where u must kill monsters 30-40mins

totally time more less 1.5 hrs? :)

the hardest think on this achievment is not go up betwen tiers;)

I have every achievement except the obtaining 10 helms/shields/swords and the 10000 mineral deposits. Personally I wish there was a way you could click on another player and view their achievements. I want to show off my easy to obtain achievements.

A friend of mine has every achievement.
