When I first saw the caltrop eruptor it sounded dangerous, so I avoided it on instinct and only disarmed it when my chance was at least 50. After a while I did step on it accidentally and saw what it's supposed to do, which is to spawn 9 more caltrops in a 3x3 area. I thought to myself "this is a neat way to get extra EXP, pick up the trap, then drop it and activate it on purpose to get 10x experience out of it." This continued until I found the Dragonsbreath Caltrop Eruptor. My god. It spawns itself. I'll be stuck here for days. How do I overcome my urge to farm infinite EXP?
Try dropping one in a zoo. I had one spawn in the level 14 zoo; it cleared about 100 of the 160 monsters by itself. I leveled. Then I ground another level disarming all the caltrops that I could pick up in the zoo. Then I maxed tinkering and disarmed the rest of the room. 2/3 of a level. Note: A stack of 1100 quantum caltrops still won't kill Dredmor.
Time to nerf his resistances again. Seriously though, how much damage does a quantum caltrop do damage wise? Because I'm fairly certain 1100 of them should do more than the 800 health he has.
His resistances are high enough to completely resist 1. So he resists 1 caltrop 1100 times in a row. Sadly, the effect of all those caltrops isn't cumulative.
Btw I've noticed that shift dropping traps reduces the stack size to 1. You have to actually spend turns dropping them to stack them up...
I'm more surprised that there are still two monsters that didn't die in a firey spiky explosion of caltropy death.
They are probably flying or outside the zoo. Also, I love these traps. But I'm just a crazy sleep-deprived person.
