He is Tyrr GK, so weapon fists, i guess he was going with cocktail buffs,
but he said that even he improved dps i mean added 20% p critical dmg augment , he does not kill more mobs compared with the same weapon without augment.
next his test was to to remove ring witch added 15% crit damage and he got less adena means that he killed less mobs. So conclusion if he was doing without augement 130kk adena with 20% aug he should do at least do more, but it did not happened
