Editing Warhammer 40,000/7th Edition Tactics/Psychic 101 (section)

==Rules Interactions to Watch Out For==

*Beams do not target models or units, so are a good way to psychically murder something that cannot be targeted, such as Invisible enemy unit.
*Profileless Witchfires quite often ignore armor saves, but because they lack a profile, the wording is usually "ignores armor saves", not "AP2", which means you disregard rules based on the AP of the weapon - for example, [[Warhammer_40,000/Tactics/Tau(7E)#Special_Characters|Aun'Va]]'s Paradox will not trigger, and you similarly get no bonus to damaging vehicles as you would from an actual AP2 weapon.
*Because a specific model can only Deny the Witch when it or a nearby model friendly to it (in the case of a Librarian's Hood, for example) is affected by a power, Blessings are inherently more powerful than Maledictions in that they are harder to Deny, as no model will get to use its special rules on it.
*Chariots are the only vehicle that allows full casting from an embarked Psyker.  All other vehicles, including buildings, only allow Witchfires, which means e.g. you can't cast a Blessing while embarked (unless embarked on a Chariot).
*Look Out, Sir works on Psychic powers just fine, including Profileless Witchfires, but it is triggered by allocating Wounds, so it can only be used if the Power inflicts wounds - for example, [[Warhammer_40,000/Tactics/Psychic_101#Tempestas_.28Space_Wolves.29|Jaws of the World Wolf]] Removes From Play without Wounding, so Look Out, Sir does not apply.
**Similar reasoning applies to Feel No Pain.
