Saeviomagy said:Frankly - a DM who has critters concentrate attacks on a familiar to the exclusion of some other activity is a jerk. There's rarely a sizeable benefit to doing so: most of the time targeting the wizard himself will be at least as good.
The exception, of course, is if the familiar is off scouting alone. A wizard would be well advised not to use his familiar as the party scout, unless said wizard is also the party rogue...
IOC, the area spells are the #1 familiar killers. In 28 years of gaming, we've had no more than a handful of characters with familiars, as a result.
