Metal Spider Temple

Here is a list of the curses inflicted as you explore. I wasn't exploring one tile at a time, so there is some error
~15 Tiles: Poison
~24 Tiles: Mana Burn
~39 Tiles: Corrosion
~44 Tiles: Corrosion
~49 Tiles: Corrosion
~55 Tiles: Weakening + Corrosion
~59 Tiles: Weakening + Corrosion
~64 Tiles: Weakening + Corrosion
~69 Tiles: Weakening + Corrosion + Warning of impending doom
~72 Tiles: Death

It is just barely possible to get the Fortitude Potion, Burn Salve, and Whupaz, allowing you to get the Whupaz with no permanent damage. If you can use the Glyph: ENDSIWAL ENDSIWAL]] glyph, then you can also get the healing potion. If you worship  Jehora Jeheyu, then venturing into the spider temple just prior to purchasing chaos avatar is another way to get out unharmed.

LEMMISI and BLUDTUPOWA attract The Spider's attention just like normal exploration.
