Notes from author
This build is my absolute favorite Int/Dex Build of all time.
With this, every bossfight in the game is going to be extremely easy. It is viable for both pvp and pve.
My build is pretty much all about trading damage. Because of that, i would have liked to use the leo ring, but i dont want to be fatrolling (but if you do not have a problem with that, feel free to use whatever ring you like). But in my opinion, the RoFaP is a absolute Must-have. It makes up for the low vitality and also gives you some equip load and stamina.
The Balder Side Sword is your first choice (fast, high dex scaling, best r2 attacks of any weapon), but i would recommend you to swap the sword for the falchion, if youre not having luck with farming it or are not used to its moveset yet (it takes some time). It is a good alternative, as it can be obtained very early in the game (especially if you have the Master key).
The secondary Weapon, Ricards Rapier, is your backup weapon. It should be used when you encounter a magic resistent enemy/player, to deal high critical damage. The Rapier has higher crit. damage but i like the moveset of Ricards Rapier more. It is also faster, which comes in handy when you buff it, because you get more damage out of the cast than with the regular rapier. Again, this weapon is only a backup weapon, so it should be used only when you really have no other options.
There is not much to say about the shield. You have to use it because your armor is actually increasing the stamina recover time. This shield is just a compensation.
About the spells: you can choose whichever you like, just note that you have to use at least one ranged spell for pvp, because often players will just try to run away from you until your castings are depleted.
Also, i should mention that artorias is a pain with this build...
Oh, and one more thing: use your castings carefully! You only have three attunement slots and the castings are halved.
Have Fun playing! See you in Drangleic ;)
