There isnāt really an eventually.
STR scales better and better at higher levels due to the Rank bonus.
Dex scales the same at all levels.
Mechanics thread has Crit Rate as
(42 x (Crit rate - Crit Resistance))/yourlevel.
The higher your level the more Dex you need to Crit because the divisor is your level.
Aka each individual point of Dex becomes worth less as you reach higher levels and crit rate doesnāt really improve by adding Dex from when you added Dex at lower levels.
Again Crit is a 1.5x modifier + Critical attack.
IF you go full dex you wont have much for Critical attack anyways so youāre basically working with a 50% modifier that is only active sometimes, giving you a less then 50% damage increase on average as a result.
This game is rather linear for the most part (with exceptions), the status quo for Dex doesnāt really change much with level at all.
If you want a good crit rate, put green gems on your gear.
For example at level 600 based on the currently accepted formulaā¦ You only need 15 Crit rate (after crit-resist reductions) to have a 1% crit rate. So 1% per 15 crit rate at level 600. You can basically get an 18%-20% crit rate from green gems alone at level 600 and thats assuming 3 sockets, if we start getting 4 or 5 sockets? Good lord. With no Dex investment. The amount of Str you could have at that point would be in the thousands as would your Crit Attack.
Dex is valuable for high skill bases, and this game is throwing more and more multi-hits with lower bases. Get Dex because you well are looking for evasion + Crits. Get Str + Green gems and some Dex if youāre looking for heavy damage. Dex is even more meagre giving the Crit rate modifiers we have in this game. Swiftstep, Finestra, Monstrance, Sneak hit, skill crit modifiers like on Multi-shot. You get crit from so many places going Dex solely for crit is kind of foolish. If you want it for the evasion sure, but evasion canāt handle everything by itself anyways, unless youāve got like a Peltasta redirecting all the damage towards him, and given how many swords are going C2 Highlander or only Peltasta C1 instead of later Pel C2/C3 for more aggro controlā¦reality is ya need Con because Dex doesnāt really do jack for hit seeking magic.
You want Str and Crit rate for damage. You can get Crit rate from many other sources, or with a small amount of Dex. Str isnāt as easy to acquire in the same light.
Then thereās the whole issue of Block, which mandates Block penetration (SPR) if something is packing heavy block.
