I have a different opinion than @JacktheRipper
Cafrisun can solo CM until 5 like there was a video in this thread showing. Manahas is much better as does the same but with more def. The conflict of opinion is around the Dex and Con. Even with manahas, or other set, I wouldnāt go full something. The Dex is a thing. Con can be invested but it does not help on many other things such as bosses and pve. Even the mobs in CM you can have more HP to survive but not more damage which by consequence you might take longer on CM and require better weapons and got more risk on time limit. And I know that as I was full Dex which is better than Con as I a full Dex I would deal a total amount of damage higher but already failed CM 5 or 4 due time-out.
AOE can help you, but isnāt your first priority as I think you are getting more important things like a good weapon first.
About the Dex, there are some tests which claimed there was a kind of stair curve in Attack speed, you can find the graphic in this thread. We consider the total amount of Dex, so you can reach that limit by just investing your points or with gears, either way is valid. Just remember that monstrance skill will increase your Dex , so when you look at the graphic, donāt reach that without monstrance skill.
About weapon, use blunt for the possibility of stun and as you may have due event or it is a good investment (cheaper than masinios) , use skull smash (one hand) , it gives a lot of int(more matk) and spr (good for sp).
Hope it clears some questions. Good game for everyone
