Hello,

So I'm lucky enough in my current world to have surface lava right near my base, with a nearby lake well above the level of the lava. As such, I'm considering using a lava blade as the killing point of my mobtrap.I've never built such a trap before, and I was wondering if it has any major shortcomings I should be aware of? Obviously it won't work on endermen, but properly built it should catch spiders just fine, correct?Is there any compelling reason to use a wall of saws instead?

Please help

I didn't find the right solution from the internet.
