Fireblast: Your main damage source untill lvl 12. Try to hit as many monsters as possible with them.
Claw mastery: Just needed to get to Burst of Speed
Burst of Speed: This skill gives us both FRW and IAS. The reason I skill it to lvl 5 is that I get a faster trap laying animation with the Leaf runeword later. Also the FRW bonus at each lvl is nice. If you want to check other Weapons out here is a good Calculator.
Wake of Fire: This is your main damage source after lvl 12 untill the end of your run. You can drop up to 5 traps. You can throw some fireblasts in between at certain points (actbosses / ancients).
