[0.4] Fire Spell on Hit Smith of Kitava

Will take a while until i make it in 0.4 to test it with those changes, since i'm going to update my Chronomancer Build first.

For now this is just idea, Gear, Tree and Gems will change.
DON'T league start or try this build, unless you brave enough!

• In 0.4 Fire Spell on Hit was buffed a lot, now it get 10% Increased Damage per level up to 200% and Spells socketed into it have 0 Manacost, while it still might be weak.
• Spell choice sadly is very limited, only Fireball and Firestorm are viable options, Detonate Dead also good but you need to spawn corpses somehow.
• Fire Spell on Hit doesn't work with channeled spells like Flameblast or Incinerate, and really bad with spells that have cooldown like Snap, or limited like Living Bomb.

It will be really good if this build can handle regular mapping, don't expect more from it considering you have to use Melee Weapon which means you lose a lot of damage from losing wand/focus or staff.

While Collapsing Horizon somewhat decent replacement of caster weapon providing up to +4 Levels, and effectively halving required Energy for triggering Fire Spell on Hit.
