Force

Force is a miracle in Dark Souls.

Availability
The Knight class has Force by default. Petrus of Thorolund will sell Force to players that are part of the Way of White covenant at the beginning of the game and later to all players. Rhea of Thorolund sells Force at a lower cost than Petrus after she is rescued from the Tomb of the Giants; Patches sells Force after Gravelord Nito has been defeated.

General Information
Each attunement slot of Force grants the player 21 uses.

A rather unique spell, Force creates a shockwave that emanates in all directions from the player, knocking over or staggering all enemies caught in the blast. The blast does no damage, but serves to slow enemies and give the player some breathing space. Force also renders all ranged attacks (be they magical or otherwise) harmless if timed right.

Force has a very short range, much shorter than its visual effect, so it may take some getting used to. Timing is thus essential when using Force. Force also does not stagger large enemies such as Giants.

Overview
Force has a number of interesting applications. In PvE, it can help to temporarily incapacitate enemies, allowing players to either escape or prepare their next attack. In PvP, Force can be used in all sorts of interesting ways. For example, successfully staggering hostile players with force at very close range can give players enough time to run behind them for the backstab. Force is visually very similar to a much more dangerous spell, Wrath of the Gods, and it can be used to intimidate and mislead enemy players into backing away from players. Yet another application of Force is purely environmental; it can easily blast enemy players off cliff faces for an easy kill, and it can demolish inanimate objects, getting rid of potentially hazardous obstacles.
