In the current tabletop game I am in, a fellow player is using the Necromancer variant.
He traded in Summon Familiar for Create Skeletal Minion. I can see it being a bit overpowered if he was a power gamer but he isnt real familiar with the rules (despite gaming for years). But I got to say his Pet Skeleton (Gorf) came in real handy at low levels. We gave him some decent armor and a bastard sword, he was useful in the front lines (He had the highest AC) And the fact that we can send him ahead to trip off traps saved our butts once.
It was kinda lucky we were based in a city of Necromancers (Hallowfaust) so he didn't attract any attention.
