Pyro PvX Build for Dark Souls Remastered. Cast speed is at max at 45 Dex. If you want to go for lvl 100 or below I would recommend dropping Vitality (down to 30 for softcap) and some points in Endurance if you are fine with your gear, stamina and fastrolling. You could also swap out the dark wood grain ring to any ringt you like and go for some heavyer armor. Take a Dex Weapon of your choice and push it +15. If you don't want to push that high into dex you should go for a Chaos-Weapon +5 instead of regular +15.
You can also start wanderer for +1 free skillpoint but I prefere to start as a pyro.
This build go a good pressure from distance and hits hard in meele but it's really a high rist/high reward build.
