3 years ago - Remove scroll of summon monsters
- Remove scroll of aggravate monsters
- Adjusted overall probability of scrolls to a lower level. Otherwise, the removal of scrolls would make the remaining scrolls more common within the game. Also took into account scroll of identify, which was removed earlier.
- The old probability for scrolls (as an item category) was 42.
- The combined frequency of identify, aggravate, and summon scrolls was 30+15+10 = 55.
- The sum frequency across scrolls was 158.
- Therefore, set the new probability for scrolls to 42*(1 - 55/158) = 27.340... = 27. This is 35% down from 42.
- The number was rounded down, as not having to use-identify items means their supply will be effectively higher anyway.
- Will have to do the same for other item categories, if some are removed (e.g. potion of hallucination).
