On my first and so far only run today, I was going for the "kill 3000 dragon shrimp" thing, so I played on Gallo Tower (level 4), and since I hadn't gotten the "survive 15 minutes with Lama" thing yet, I picked himher as my character (the dudechick who starts with the axe). Well, though I didn't get the kill 3000 dragon shrimp thing, I did survive 15 minutes as Lama and also hit level 99 (actually around 105 or some such by the end) with himher, which unlocked another Arcana, but, more importantly, I also pretty easily (more easily than I thought it would be) got the "evolve all six weapons" thing (using axe, whip, wand, cross, bible, and garlic, all evolved by around the 20 minute mark), which unlocked Torrona's Box. Haven't played with that yet, so dunno how busted it really is though it sounds pretty busted, but that's probably my next goal later. That and to continue the "kill 3000 dragon shrimp" thing.

And yeah, at least until Death showed up and insta-killed me at 30 minutes, I probably could have just parked Lama somewhere and walked away from the game. Also, even though I saved the "suck all items to you" Arcana as the last one I got this time (since I only had that and two others unlocked at the time and was forced to pick a third one after the 22 minute mark), I was still able to max all of the four hidden items in the time remaining. Also killed those four "mega"-bosses that spawn with those in about a minute or so after they arrived, if even that long (i.e. basically four "free" Golden Eggs for Lama). The only reason Death insta-killed me was because I didn't have anything mitigating damage and didn't have the time stop weapon. When I play Gallo Tower again, I'll probably go for evolving the Lancet and Laurel again, so that I can at the very least get the "survive 31 minutes" thing (which you can do without evolving those, as long as you at least have them) for Gallo, if not actually kill Death again.
