when a knight is heavy-blown and his shield is close to shatter do his muscles really matter or they're nothing on their own? in this experiment we were testing the dependence of block chance of tank classes from their con. othell adventurer was chosen as attacker, sigel phoenix knight was the defender. he was attacked both from the front and the back side with reverse (lvl 4). after each series of experiments con was increased. each conducted experiment involved 500 hits with reverse. experiments count only misses and 1 damage blocks, since with such powerful buffs sigel knight is able to block every single attack. sigel phoenix knight’s buffs and equipment: the results are the following: conclusion. as we can see, con does not affect the probability of successful shield block significantly. adding 45 points to con didn’t increase the successful block probability even by 3%. the probability increase is not significant while attacking both from the front and the back sides.
