DEX GODMODE IS FALSE (Express Gameplay)
Without any armor or runes, at DEX stat point 412, you are, in theory, invulnerable. You will have exactly 100% DDG (Dodge) and well over 100% ACC (Accuracy). I stopped there and gathered aggression to test this. The mobs missed consistently until Beeti's solidly hit around 30% of the time, Pitz hit 10% of the time.
This concludes a few things,
(1) Mobs might have an absolute hit roll
(2) Some mobs have a passive skill to ignore defence/dodge
(3) Just because you avoid an attack from a mob/boss, does not mean you avoid the skills extra stats like element (Ice/Slow, Fire/Burn, Electric/Half Attack) or status (Decreased defence, Stunned, etc)
After the above, I questioned if having 100% is similar to 0%. So applying more points to DEX, somewhere near +1000 (one thousand) you will LOSE all points and reset to an visual 0%. Shocked I gain aggression, and was hit 100% of the time from every mob/boss yet the damage was minimal.
Further investigation is needed, however. I highly doubt anyone of you adventurers will go pure Dex (highly discouraged) Though, I say that, I'm pretty sure one of you will do it anyways. Have fun with that ruined character <3 (Unless stat reset scroll)
