tags: [skills] “battle rhapsody!” – girls shouted, as the battles used to go, this skill was – it is undoubted - only one they got to know. purpose: to measure stats influence on the chance of battle rhapsody time doubling. part 1 iss dominator, lvl. 99 cast battle rhapsody not being in a party. to check the stats influence on battle rhapsody duration doubling we increased stats up to maximum one by one and made a sample of 500experiments for each value. results: str slightly affects the chance of battle rhapsody duration doubling. part 2 iss dominator, lvl. 99 cast battle rhapsody being in a party with othell rogue, lvl. 99. the sample is the same: 500 casts divided into 5 groups, 100 hits each. first both characters had basic stats, and then othell's stats were increased up to maximum taking his passive skill superior critical mastery into account. results: as we see, othell's passive skill superior critical mastery doesn't affect battle rhapsody duration doubling. finally we decided to conduct another experiment and set the battle rhapsody skill to othell rogue. part 3 in the final part of the experiment othell rogue, lvl. 99 cast battle rhapsody being in a party with iss dominator and out of it. in both cases othell's str was 200. conclusion: iss dominator's str not significantly affects the chance of battle rhapsody duration doubling. the chance of time doubling depends only on iss dominator's passive skill superior dual weapon mastery and is not affected by any other party members' passive skills such as superior critical mastery and superior critical arrow.
