Rabid Rabbits
Head to this NPC on the north western area of Radiance to begin this side-quest.
Here you will find Alaster. He is having trouble with some pests. So offer to help him.
Th rabbits will be behind his house, across the canal.
The rabid rabbits will rush at you all at once (per "party"), so if you have a tank / tough character, send him out first to take in the damage.
Keep neutralizing the rabbits. After you kill 10 of them, the task is done.
Return to Alaster and submit the quest for your reward.
