A Psyker automatically generates his full allocation of Warp Charge points at the start of each turn. There's no need to do anything -
it happens automatically. It's important to keep track of Warp Charge across the turn, either by making notes on your army roster, or by marking the Psyker with counters.
Once a Warp Charge point has been used, it's gone. Any unused Warp Charge points are lost at the end of the turn.
Eor example a model with the Psyher (Mastery Level2) special rule generates two Warp Charge points at the start of each turn.
Similarly, a model with a special rule that allows it to use three psychic powers a turn, and is therefore a Psyher (Mastery Level3),
generates three Warp Charge points at the start of each turn
