Updated to version v1.1, this has a few balance changes in addition to a few bug fixes and some items have been added to the pool.

• + All Artefact Armour and Weapons are now item_level 10, up from item_level 0 so they will spawn in late game shops instead of rocks, and will spawn more frequently late game, but less frequently earlier on.
  
• Crystal Armour and Weapons are now item_level 10, up from item_level 0, this includes shurikens and the compound bow. This will also make them more of a mid-game itemset rather than too rare or too common.
  
• The Arbalest, Executioner's Hood, Shaman Mask, Boomerang, and Whip are now item_level 10, up from item_level 0 to better reflect their usefulness (or in the case of the arbalest, pool dilution.)
  
• Crystal, Piercing, and Hunting Arrows are now item_level 10, up from item_level 0.
  
• Tinkering Constructions, Bombs, Scrap, and Empty Bottles now exist in the item pool at item_level 0, thus they will start appearing in any runs.
  
• Spellbook of _9 and Spellbook of _10, which are unlearnable forms of the arthropod form and spray web spell may now spawn as gag items, and also since they don't actually crash the game.

Published Mod in Version 1.0 after some testing in Singleplayer.

Known Issues

• High-Tier Shopkeepers are bugged and will only spawn rocks.
  
• Tinkering Contraptions and some similar non-harmful items should be re-enabled soon.
