Really, I know by own experience, I have been the vet and I have been the vet´s teammate
Dont bait d1, there is no effective bait that isnt easily spoted by an evil with half a brain, alert n1 without baiting is usually a russian roulette, except that your gun has 4 bullets in it, and mafia's gun has only 1
Most of times alert n1 means that you either wasted completely an alert, or that you killed a townie, sure getting confirmed isnt bad, but as vet is not a good idea to get confirmed on N1 because unless you get to a 1v1, then your ability is now useless
Really, you have way better chances if you bait d2 or afterwards, its even better if you are jailed because you can tell jailor that you are planning to fake claim so you have 1 guy who might be defending you
Bait d1 has a low chance of succes because it is too predictable, if you claim bg or vigi then its obvius
However bait on d2 or d3 has higher chances of succes, claim rbed spy, claim bg, claim med if someone died to ambusher, but obviusly dont claim without context or evils will catch the bluff
If you claim med then say smth like "deads dont leave"
or if you claim bg then say something stupid near the end of the day to draw attention and get asked to claim
just dont alert n1 unless its all any
