This mod represents a compilation of PnP related tweaks and various house rules which are designed to bring more consistency to the gameplay. It works on normal Baldur's Gate II games as well as either of the two Baldur's Gate conversion projects: (Easy)Tutu and Baldur's Gate Trilogy (BGT).
In summary, aTweaks can bring several classes, races, spells, items and creatures closer to their PnP counterparts, add more consistency to the gameplay by making sensible rule adjustments and eliminating exploits, and make it easier to distinguish between creatures with similar avatars through the use of recoloring techniques.
The mod is divided into multiple components all of which can be installed separately and are completely independent of each other. More detailed descriptions of all components can be found in the readme.
