Spirit of Fire

Last boss of Scrapper level Pit #10. Though it resembles a Hellfire Fighter it is much weaker than one.

A spirit of fire attacks in melee range. A spirit of fire never retreats.

It's Recommended to use Protection Amulet to reduce physical damages.
Druid or Sorcerer: Use Magic Shield and shoot SD as fast as you can if your level is lower than 50. If your level is 45 or lower use 1 to 4 SSA to make mana last longer since almost all the damage you take is melee. At level 70 or higher you can use Ice Strike and Exura.
Knight: Use melee and Exori and Strong Health Potions. Make sure your health is always high because this boss can take even experienced knights down with big combos.
Paladin: Use Shield, Ethereal Spear and maybe even Icicle to kill him fast.
