Use Grimoire 3.8+ (latest version here: https://www.mpgh.net/forum/showthread.php?t=1452109) for this because it may not load for older versions. Just equip a single-target spammable class (preferably LightCaster) so that the quest turn-in doesn't get stuck. If you don't want the quest drops, feel free to remove them from the whitelist. Enjoy botting.
