Tzeentch

CHARACTERS in a TZEENTCH Chaos Daemons detachment have the following ability: Roll 2 dice at the start of each Fight phase and discard the highest result. Until the end of that phase, each time your opponent targets a TZEENTCH DAEMON unit within 6" of a friendly model with the Locus of Trickery and makes a hit roll that, after re-rolls but before modifiers, matches your remaining dice result, that hit roll fails.
