It further offers a large number of tailored components that modify individual set-piece encounters at various points throughout the two games. It carries out a fairly systematic restructing of the games' core artificial intelligence, affecting spell and proficiency choices, kits, high-level abilities, and most importantly enemy AI scripting, with a full install rewriting the AI of practically every creature in the game, though in most cases without significantly affecting their core abilities.
Sword Coast Stratagems contains many optional tweaks to various aspects of gameplay, including a full implementation of the Icewind Dale spell system, but at its core it is a tactical/AI mod. (It is not compatible with the original BG1, or with the original BG2 without Throne of Bhaal.) It is compatible with the Enhanced Editions of Baldur's Gate I and II, the original edition of Baldur's Gate II with the Throne of Bhaal extension, with the 'EasyTUTU' conversion of Baldur's Gate to the Baldur's Gate II engine, and with the 'Baldur's Gate Trilogy' and 'Enhanced Edition Trilogy' combinations of the two games. Sword Coast Stratagems is a collection of mini-mods for Baldur's Gate series of games.
