The trip mines are much harder to use strategically than I would have thought.
You have to place them far away from one another for one thing, otherwise the explosion from one will set off the other, wasting a mine. Secondly, enemies will go around the trip mine, most of them, unless you specifically bait them into going over it. But that requires standing near it, but if you’re near it when it goes off, you die along with the enemy, so you have to stand near it, and then back away. But you can’t back away into another mine you laid down.
Anyway, I stopped overthinking it and just lay down three mines at the start of the battle and switch to the other weapons now. But on the other hand, I still can’t win this battle, so maybe that was not a good strategy after all.
Still fun to try to figure this out though. All these monsters coming at me also drop loot. And I want to pick that up during the battle as well, because I have to leave the room at the end of the fight, so anything I don’t pick up is lost. Maybe I’m being too greedy by trying to pick up the loot as well? Hmmm.
