Glitches and Mechanics
Item Duplication
Save/Load
Loading a savegame, while items are travelling in the air, restults in them landing in this savegame. So in order to duplicate an item, save the game, throw the item and load while it's still travelling.
Movement
Cutscenes
Repeatedly clicking the ground while a cutscene is running allows the character to keep moving during it.
Movement Directions
In the early Divinity games, players move faster diagonally than straight forward. So while running at 45°, the players speed is 1.41x of normal speed. This applies similarly to all 16 directions of movement.
While running right and slightly up or left and slightly down, repeatedly clicking results in the player getting1.5x horizontal speed (or 1.58x overall).
Throwing pyramids
Scrolling to a desired location and throwing a pyramid to teleport there is in itself a quick way to move around. Having duplicated a pyramid and split dropping it, results in it landing instantly, cutting out the time it would take for it to fly there.
