Monsters now are less fixated on getting extra-close to their target before making a melee attack. Monsters were failing to cast spells on themselves, due to a bug. Monsters are less dumb now. Banderlings and Black Drudges now cast more slowly. This has been changed.
Skeletons have higher levels, to reflect their challenge.
Lugians can now throw boulders faster and farther than before. There were small glitches in the data for some types of Gromnies, Drudges, Armoredillos, Golems, Olthoi, Mu-miyah and Virindi, which gave each of them inordinately low or high protection against a specific damage type. These have been fixed. Magma Golems have been learning from the mages that attack them . . . Aqua Incanta and Neutral Balm are now available with many more vendors.
