Sword Coast Stratagems is a collection of interconnected mini-mods for Baldur's Gate (on the BGT/BGTUTU/BGEE versions) and Baldur's Gate II. It is primarily a tactical and AI-enhancement mod: the idea is to make the game's combat more interesting, tactically challenging, and realistic by more effective use of, and choices of, creatures' abilities. It also contains a few rule tweaks and ease-of-use features.
Version 33 is largely a bug-fixing release: it features fixes to 40-odd bugs and compatibility issues, including serious problems with the NPC customization component, the random scrolls component, and Death Spell (which was turning neutrals hostile). It also adds a small new cosmetic component (improved Tales of the Sword Coast textscreens), allows IWD spells to be tied to hotkeys, tweaks the shapeshifter tokens, and makes some slight changes to mage and priest AI.
