Why does dex based ranger with over 50 dex fail knockdown save on a roll of 19 in heroic quest?
Or is it like FR drow paralysis poison which is no save?
I've seen that a number of heroic quests with parts that have knockdown effect have insanely high save DC that even toon with focus in required stat (STR or DEX) fails on roll of 19.
My guess is that as usual for SSG they put save DC for knockdown in range of expected for example reflex check which are quite higher than what you can get for stat save. and as usual forget that stat check has NOTICEABLY lower possible modifier than fore example reflex check...
Otherwise I don't know how could DEX check in heroic quest have save DC so high that toon with over 50 DEX fails it on roll of 19...
