Your level 9 sword and spear will be your best friends when leveling up. The level 9 spear is still my favorite to use. The L1+triangle attack is useful as a semi-block attack and it pushes the enemy back. the L1+square is also useful for pushing enemies back and tethering them but it is a bit slow to use and can be easily countered. For the best effect, use Square+square+triangle and keep hitting triangle to perform a devestating combo. As far as elemental power, the ice maelstorm is killer but it'll take a lot of mana to cast. I personally like the first spell you get because you can hold two charges which is very useful for when you're being double-teamed.
