^Since I can't edit that^
Here's the picture which didn't upload.

I'm posting within a window within a window!
(From pressing the "edit" button, no less.)

There are some things man was never meant to know...
The very act of trying to piece together the numbers may well drive you insane!

/on topic:
If I can harvest some spare time, I might look into this.

That new thread you made (cutest thing ever) brought my browser to a grinding halt, then refused to play anything but the audio whilst the browser adamantly refused to let me do anything about it.

I point the rigid finger of accusation at the new youtube embed change

BUT i'll go try it again just in case.

EDIT: Upon reloading the page, the video worked as normal... up until the youtube player became unresponsive and kept on playing the video regardless of what I clicked.
Starting to think it could possibly be something on my end.

This would be my guess too.
Perhaps a small magical barrier is made, allowing air particles through but blocking spores, magical bubbles and the like. Oh, and minute stink particles of various origins. Basically anything but air.

Or treants even, which only attack once you're very close to them. (i.e. Set their perception very low)

I suppose you could make 4 individual tree wall entities that are 1 tile each, and then simply arrange them in the right order to make them a tree.

E.g.

      OTerrainMap
      {
        Pos = 0,0;
        Size = 17,19;
        Types
        {
          _ = 0;
          # = 0;
          p = GOLD wall(BRICK_PROPAGANDA);
          $ = GOLD wall(BRICK_FINE);
          ^ = decoration(HOLY_TREE);
          c = decoration(COUCH);
          d = EBONY_WOOD door;
          o = EBONY_WOOD wall(BRICK_FINE|WINDOW);
          T = BIGTREE_WOOD treetopleft;
          Y = BIGTREE_WOOD treetopright;
          U = BIGTREE_WOOD treebottomright;
          I = BIGTREE_WOOD treebottomleft;
        }
      }
      {
        .#o##o##o##o##o#.
        ##.............##
        o...............o
        #.....$$p$$.....#
        #...$$$___$$$...#
        #..$$_______$$..#
        o..$___TY____$..o
        #..$___IU____$..#
        #..$_________$..#
        o..$$_______$$..o
        #...$$_____$$...#
        #....$$___$$....#
        o.....$___$.....o
        #.....$___$.....#
        #.....$___$.....#
        #.....$___$.....#
        o...............o
        ##.............##
        .#o##o##d##o##o#.

And then just make the BIGTREE_WOOD material have such a high strength that it's nigh indestructable (and make it non-wishable too!)
Of course you couldn't have them spawned properly unless they were in pre-defined spots or you made one of those "random room" entries that contained only the tree.

Raise your endurance too high.
I've found them below GC 7 but I think they're just stats based spawns of mistresses.

Yeah, I hadn't seen Psypher before, but yes it's in the script files for LIVAN.

Heh I know how you feel Eagle V. The only times i've gotten past the Enner I always either died in the massive zombie level or by Mystic Dark Frogs teleporting my stuff away.
And i've only killed the Enner a couple of times, and both were because I had a bunch of wands.
