What are the items of raigor in dota?

Raigor is one of the heroes who can go two ways, as a spellcaster, or as a damage dealer. I prefer to go the way of damage instead of relying on his spells, which means getting battlefury and heart. However, if you'd like to try out a caster Raigor, Shiva's or Guinsoo would be a good choice.
