In this experiment, an influence of character’s level (support class) on the drop from usual monsters and raid boss has been tested. Attacker: 48 lvl Hawkeye, having all the skills. Equipment: Eminence Bow Buffs: buffs of support class Support Class: 56 lvl Overlord or 61 lvl Overlord while killing the usual monsters; having all the skills, but without any equipment. Buffs: his own buffs Target: 48 lvl Cave Servant Warrior, 48 lvl Raid Boss King Tarlk. Drop: Animal Bone Fragment (from usual monster), Scroll: Enchant Armor (C-grade) Three experiments for a usual monster and another three for raid bosses have been conducted. In the first experiment, a drop rate of the certain item was checked. During the second one, support class was continually using its buffs and, in the last one, the Overlord was using debuffs, that don’t bring damage. In each test 400 monsters/raid bosses have been killed. The results are stated below: Without Penalty 42,5% 100% Buffs 43,0% 100% Debuffs 44,5% 100% Summary: as it can be seen from the test, support class doesn’t influence the drop rate if it is using a skill which doesn’t harm the monsters.
