Alright. Im gonna try.
So I started out pretty well. I found a book of avitus and some good gear for plant killing. After a while I found another and after some reading got the anacadite plate mail. I decided to take a risk and go to silvas level. I managed to avoid the golem and get a +3 steel spear and some other goodies. I gathered up some corpses and some other things that might seem useful.
At turn 1538 I entered the plant level.
kicked a door and lost some potions to an explosion, but I survived so it was ok.
I found some gauntlets of strength giving me total protection
at 4775 i was still alive, a plant got a lucky hit on my leg and nearly crippled me but I got out just barely. so far so good!
I am at the point that I am overfed on kiwis, foods not much of a problem anymore.
5594, NEARLY BITTEN TO BITS BY PLANTS. All of my limbs turned black, but sophos saved me at the last second. I went to hide but shortly after I was attacked by plants yet again.
5598, I tried to escape by zapping a wand of lightning but it bounced and killed me. What a stupid way to die. But I still did pretty ok.
final score: 4060 turns
final kills:
45 small plants
94 medium plants
111 large plants
250 plants total.
Good luck beating that!
