I have no idea what you mean by Fluid drain. your description matches that of Chest drain.
But I'm assuming you mean Space drain.
Which I had to go digging for the name. as you mentioned, pretty forgettable.
It is supposed to remove fluids around where it is used.
Actually useful if you're bound to sleep and have no energy drinks. The thing is, you have to drop into water and then use it to suck the last layer in, otherwise it tries to suck in at your body level which is always higher than water level, unless you're ragdolling... that could work too.
You're telling me that the game kept the best items from you for last? ;p
You see, my mentality with Landmines right now is as follows:
- NEVER drop inside a driedbush (eventhough it can be lifesaving to hop in)
- NEVER just walk through stoneplants, corpses, etc... JUMP OVER THEM INSTEAD
- NEVER touch the bottom of an oil ocean, lake, or a humble pond. (without excessive eyeballing first, easier said than done)
- NEVER dig a driedbush close by another driedbush, unless you can manage an insta flight response in the opposite direction.
- I'd say also never get stunned xD, but frankly, that counts for every trap in the game.
You do ALL THESE, PERFECTLY, ALL THE TIME, and you have 10% chance of a landmine ending your run anyway.
OH WAIT, I took too long and the new update dropped. Well, now it's all about seeing how the balancing is handled
