Most of the skills can only be used one at a time with the exception of Hand Sonic. Hand Sonic can be used in combination with the other techniques. There is no time wait between skills. Clones created using the Harmonics skill can use any skill that the original can. There is no limit to the number of times you can use any skill other than your own personal stamina and physical well-being. Freeze Lattice expires after 5 minutes, then you need to set up points again to use it. Harmonics expires after 30 seconds when Absorb goes into effect.
