in this experiment we shall check noble critical focus skill by comparing it to mega strike skill of tyrr duelist with different values of str parameter. attacker: tyrr duelist lv. 99 with all skills learnt. equipment: blessed amaranthine slasher [focus + damage], blessed eternal set [attack type/heavy]. buffs: all poems, sonatas and warrior’s harmony. target: tyrr duelist lv.99 with all skills learnt. equipment: blessed eternal set [attack type/heavy] buffs: all poems, sonatas and warrior’s harmony. the attacker did 1000 hits with mega strike skill in each of 6 tests with 3 different values of str. in first three test, the attacker has noble critical focus, and in three last tests he does not. the results are shown in the table below: {tbody}{tr}strfocuschance{tr}105-6,5%{tr}105+7,0%{tr}110-6,6%{tr}110+6,8%{tr}140-6,7%{tr}140+7,2%{/tr}{/tr}{/tr}{/tr}{/tr}{/tr}{/tr}{/tbody} conclusion: as results indicate, skill critical attack chance has increased, but very slightly.
