Oil. Cheap and weightless. Burn all the things.
Caltrops. Fill a bag of holding with them (guard against punctures), then just litter every square of a dungeon or battlefield.
What else could potentially wreak havoc?
2000 copper pieces in a bag of weasels.
Litter the floor with a bunch of tiny boxes that all say “Glyph of Warding”.
Edit: It does help if one of them is actually armed. That way the enemies will always be guessing.
Honestly, by the time you can afford a Bag of Holding, caltrops will be nearly irrelevant, even if covering every square of a dungeon or battlefield (which itself is a labor). Now if you're a GM on the other hand...
Oil works well at the lowest levels, yet I'm unsure it's worth the actions after that, even to dump a barrel (despite the dramatic imagery). Though again, a GM might get a good visual out of it while keeping it manageable for the PCs to bravely enter.
Release the weasels in a social setting? To set off traps & ambushes?
Not sure the boxes would even need to say "Glyph of Warding" if they're distinguishable and the first one goes "BOOM!". Could even use pictographs like a picture of fire, another of lightning, etc. with a few that explode to match their image. Transcends language.
This again feels more like a GM tactic, though I suppose if one has extended interaction with a specific group of enemies it might work.
So what exactly is meant by "spamming encounters" because I don't see these as things PCs would spam? Now if the PCs had subordinates who lack useful contribution, then maybe...
when are approximately 1000 weasels not a good idea?
when are approximately 1000 weasels not a good idea?
When you are running a chicken farm.
Nothing to do with dungeons, but it answers the question.
2000 copper pieces in a bag of weasels.Why not just empty some bags of flour in at that point?
I could see spamming flour. It'd hinder invisible enemies and you could easily spot tracks in less linear dungeons. And it'd probably perplex them as they wonder why you brought so much flour.

I could go on.
