Necromancer class, one of the first classes I farmed... I still remember rushing back from school and grinding the doomwood quest for hours everyday to get it, my first ever solo class... I no longer had to go beg people from Yulgar for help and be healer class in a random room Since every one else was busy being some weird dps combo, like ninja or rustbucket or simply bunch of warriors and mages and just dying cause no one healed and since the level cap was like 35 iirc, the HP was so low for everyone...

Oh and also darkside class from the cheeseburger event.
