Be a Daugther of Izalith by using pyros and sorceries to destroy your enemies.
This is more a PvE-Build, but can also be very useful in PvP if you like. To fit the theme behind this build you should stay near 40 Int to use the Izalith Catalyst properly. Everything above makes this catalyst useless.
Most of your damage comes from your magic, the Furysword is just a backup and fits the theme properly. If you don't like this weapon you have some points left until you reach SL120 so you can vary with your Str and Dex.
Thanks for watching and have fun!
