Electrically Charged Water
From WikiRaider
Electrically Charged Water is a Trap that features in Tomb Raider Chronicles in the level Sinking Submarine in several rooms and once in Tomb Raider Legend in the beginning of the level England - King Arthur's Tomb?.
Electrically Charged Water causes quite a lot of damage, and there's ususally a way to avoid touching it, for example traversing along ledges or jumping onto platforms. In Tomb Raider Chronicles Lara shuts the power down by using a jump switch, which deactivates the trap.
