Do you mean when attacking elves, dwarves and halflings? The rules don't say anything specific (in general they are very terse). My interpretation is that if the target is not a "classed" character, you would look them up in the monsters listing and thus it would apply only against halflings which have 1-1 HD.@Nikosandros, I have yet another question if you'll indulge me (again!). Does the Fighter combat dominance option (multiple attacks versus creatures under 1 HD) apply to race-classes like Dwarf, Elf, Halfling, etc.? Is it ever made explicit in the text one way or the other?
