a weapon changer that would allow me to change from a rod (moonlite) 3070 to
a weapon (spike sword) 3271
when I come across these monsters (spiders, bugs, rats bats and snakes) and then
change back to the rod as soon as bot doesn't see any of them mobs on screen again (maybe with a little wait period)

I thought I seen something like this in forums
but I have searched for a day or so and cannot find it
