In this experiment, a normal damage on different types of armor made by arrows was checked. Attacker: 105 lvl Archer, having all skills, but without any buffs. Equipment: «Amaranthine Thrower». Target: 105 lvl Archer, without any skills or buffs. Equipment: depends on the test (sets with different enchantment level and comparable defense). During this test, the attacker was inflicting damage on the target (without damage spread) with basic attack. The result is stated in the table: Item Defense Damage Heavy Armor Eternal Set (Attack Type / Heavy) 2346 279 Eternal Leather Set (Assassin Type / Light) 2345 279 Magic Armor Eternal Set (Magic Type/Robe) 2343 279 Summary: as it can be seen from the table, despite a small difference in P. Def., a type of armor hasn’t influenced the damage.
You want to tell us that in Robe set yul have only 3pdef less than in heavy and 2 pdef less than light ?
I'm always amazed at how people have no clue about what is tested. The stats here are the same BECAUSE the test isn't to test the difference of pdef between sets (do maths for that), but to be sure that there is no "hidden" skill that reduces arrow dmg by heavy armor for example. The usefulnes of the test is another story, but for what was tested, it was properly done.
