Shinsu

Shinsoo is an energy that flows through the Tower. It grows in density as the floors go up. It can be used as an attack and defence by those who climb the tower. Wave Controllers specialise in using it, but all positions have to learn it eventually in order to climb successfully. Irregulars have a special talent for using it.

Shinsoo is gathered in "rooms" which are essentially mini-stores of Shinsoo for users to draw power from. It is quite hard to create more than one room. When all a Shinsoo user's rooms run out, he cannot use Shinsoo without gathering a lot more.

Shinsoo varies depending on who uses it. Some people's Shinsoo flows like waves, other people's is electric.
