Uber (accessed from 23,23,15)

This is incomplete and a couple errors are still present.  The skull and crossbones represent what I call a 'pirate base' which often contains dread pirates.  The tp codes 2,3 and 4 and the squiggly arrow go to off map areas.  It is known that a char can return to this level from the 3 tp.  There are symbols for quicksand (the upreaching hand) and whirlpools (coil shaped line).  There are other unmapped traps.  In particular, along the water on the western end, I believe there is a facer I haven't yet fixed in place.  So far, I have had few, in any, encounters on this level that I would call UBER.  I am unsure whether the off map tps and waterfall go to separate unmapped grids or the same.  The area of the yellow triangle also (I think) has a facer thereabouts.  The green dot is where you land coming from the one-way stair at 23,23,15 (but there is an encounter when you land).  There are (my) usual symbols for scatter, spear trap and acid trap.  Various places in the water areas give you the 'Beware the grottos' warning.

Jul 25: The down tp at 21,13,15 takes you to this level also.  The landing here (currently unmarked) for that tp is 24,14.
