Power of the C'tan: Time's Arrow

Before the battle, generate the Powers of the C'tan for each C'tan SHARD using the table below.  Roll a D6 to generate their powers randomly (re-rolling any duplicate results).  Before the battle, you can instead choose the powers each of these units have, but if you do this, you cannot choose a power for a second time until all six have been chosen once each (similarly, you cannot choose a power for a third time until all six have been chosen twice each, and so on).

1) Antimatter Meteor
2) Time's Arrow
3) Sky of Falling Stars
4) Cosmic Fire
5) Seismic Assault
6) Transdimensional Thunderbolt
