Having skill points allocated to this ability encourages the player to mix combat equally between melee and gun-play. As with most abilities under the Bloodshed skill tree, Be Like Water is not conducive to long-distance play styles; however, players who prefer or perform well in short to medium ranges will gain a significant edge in combat.
As an example tactic, the skill may be utilized in a Guerrilla warfare fashion by firing at enemies initially, utilizing Decepti0n to close the distance to the target, and then switching between melee attacks and firing a short range, high power weapon such as a Shotgun while strafing around the target. This tactic which can be further augmented by Zer0's Execute ability.
This ability becomes less useful with Bloodshed's final tier skill Many Must Fall, as players will become far more reliant on melee attacks to extend Decepti0n's length.
It can also be utilized to complement other skill trees, most notably the Cunning skill tree. In particular, Deathmark may be applied through melee, and the following gun attack can become devastating by the bonuses applied through both skills.
The name of this skill is taken from a famous quote by martial artist/actor Bruce Lee: "Be like water making its way through cracks. Do not be assertive, but adjust to the object, and you shall find a way round or through it. If nothing within you stays rigid, outward things will disclose themselves. Empty your mind, be formless. Shapeless, like water. If you put water into a cup, it becomes the cup. You put water into a bottle and it becomes the bottle. You put it in a teapot it becomes the teapot. Now, water can flow or it can crash. Be water my friend." The reason for the name is from the idea that by rapidly switching forms from melee to gunplay to adapt to a situation.
