Warp Reality

If manifested, select one terrain feature within
18" of this psyker, then select one enemy unit
within 3" of that terrain feature. Until the start
of your next Psychic phase, halve that unit's
Move characteristic and subtract 1 from Advance
rolls and charge rolls made for that unit.
The psyker pulls at the very fabric of reality,
causing battlefield features to mutate into warp
monstrosities that hinder Tzeentch's foes.
