Welcome to Librarium Online!
but does anyone know if the LD psychic powers and the Dooms' drain life ability work on fearless models? a lot of things in the book specifically state they don't work on fearless models but some don't.
As long as it is a normal leadership test, fearlessness does NOT protect against it. Unless stated otherwise, fearless models have to take leadership testes.
'Thou shalt not refer to the Adeptus Soritas as "Bolter Bitches" nor shalt thou go anywhere near our sisters during the time of the "Red Rage," lest thou wishes to be the first human to enter orbit without the aid of a shuttle.'
Indeed - fearless means you automatically pass morale tests. All morale tests are leadership tests, but not all leadership tests are morale tests.
This post involves too many instances of the word 'test'.
