If stupid model joins a unit with Imm. Psych. is it take stupidity tests ? example if Saurus hero on Cold one join a slann and temple guards unit...is that unit needs stupidity checks ?
Interesting question. Had to pull out the reference material for this one. The first question implied to me is: Does Immune to Psychology remove the Stupidity? Since Stupid creatures are also Immune to Psychology, then the obvious answer is no. Immune to Psychology does not prevent Stupidity. The next question is: What happens to the unit with a Stupid character in it? Hope that answers the question.
You seem to have hit the nail on the head there. Stupidity still happens, and if a character is stupid it effects the whole unit. So probably not a good idea to put a cold one in some TG.
Or a character with Hide of the Cold Ones in a unit of TG, to add to your sentence Stewart. Unless, of course, you don't care if your whole TG/Slann unit goes stupid.
Remember that in 7th edition, Immune to Psychology was changed to only work for Panic, Fear and Terror (as well as disallowing fleeing as a charge reaction). In 6th edition, units were not effected by ANY pychology rule. Many people have not noticed this change.
And isnt "Immune to Psychology" quite an inappropriate name at this point? Really, I think we should start a petition to have the ability changed to "Immune to Some, but Not Most and With Several Expections, Psychology".
What about immune to morale, where morale encompases fear terror and panic? Or hell even a rule called brave. That would be amusing though 'immune to a few things that we felt like adding'.
I'll add that Psychology also Stupidity tests, according to the BRB. Call me strange if you'd like but I can still see why they're called Psychology tests and that units who are ItP are named fittingly so. Here's my line of thinking, any other test, aside from Fear, Terror or Stupidity (which are technically the only Psy tests) have specific names and mechanics related around them. Panic tests are due to taking casualties, a larger unit fleeing through that unit, a unit breaks from combat or is destroyed withing 6" of the unit and are therefor not psycology tests. Break tests are not psychology tests because they are related to CC. Rally tests are not psy tests because the unit has already suffer from some kind of pyschological problem and the mechanic allows you to regain controll of them. This helps me remember the difference and I'll add that my opinion leads me to think that GW did a good job in trying to simplify how these tests were take and while I haven't done a direct comparison (6th vs 7th), it has always been easier for me to understand the rules behind 7th edition psy rules as compared to previous editions.
Panic and rally rolls are most definitely psychology tests. Also I'll throw in that the title "Immune to Psychology" carries other benefits with it aside from fear, terror, and panic. One example is the Master Rune of Challenge of the Dwarves, which forces a target unit to declare a charge against the bearer of the rune OR ELSE they must flee directly away from the Dwarf using the rune. There are little items and other things scattered about that make reference to Immune to Psych.
I won't argue with the fact that they technically are psychology tests, however, the book doesn't really classify them as psychology tests, which was my point. In the book, they are named Panic Tests and Rally Tests, respectively. I was just making a point of how I think of the tests and why the Immune to Psychology rule (which doesn't include various tests) makes sense to me. I'll admit though, I made some definitive statements which were worded to sound as though I was taking an authoritative stance on the rules.
