GMS Unleashed - bugs and problems

okay this solves the stat issue, but i'm still not getting a 70% boost in the avoid stat from side step + shadow meld + MT as you claim nor thr 70% dodge rate i was experiencing prior

Because it doesn't multiply on to the avoid stat.
Here's an example calculation:
Say a monster has 169 accuracy.
Say you're a DB with 6400 avoid. The Avoid +x% stat is applied prior to this. Evasion rate isn't applied here.

First you take the square root of its accuracy and subtract it from the square root of your avoid.
sqrt(6400) - sqrt(169) = 80 - 13 = 63%

That monster has a 63% miss chance. Now we multiply that miss chance by your Evasion Rate, which is 1.7x as a DB. 63% * 1.7 is 107.1%, at this point of the calculation, if the chance is greater than 100%, it would be reduced down to 100%, which means it would always miss before the patch, however, now that the cap on missing is 90% (effectively, they changed the last step of the calculation from rounding down to 100% to rounding down to 90%), since your miss rate is 107.1%, which is greater than 90%, your miss chance is reduced down to 90%, and you still get hit 10% of the time.

After this, if the monster is still able to hit you, whatever Dodge skill you have, which, again, Dual Blades don't have, is applied, leading to either a dodge or a hit.
