Wide Scan is an ability available to Ranger and Beastmaster. It is always available and is subbable. From what I understand, the Ranger or Beastmaster job level affects scan radius, with Ranger having the larger radius at a given level, but I haven't seen full details on this...

As for Bogy, I soloed one in Buburimu with some difficulty, but I'm not sure now on what character at what level... I nearly got killed and had to CFH one in Valkurm at WHM39, but I was just raising and trying to protect someone and ended up being almost out of MP when the fight started, so it was almost pure melee (though I did 2-hour the first time my HP nearly ran out).

If properly equipped and buffed, WHM can be an effective solo job. You'll definitely want to pick up some melee-oriented gear and the best hammer you can get for your level (I'm still working on Alchemy so I can synth Koren a Holy Maul). Make sure your club skill is well-leveled.

As far as getting rare mobs like Ghouls in Valkurm, I wish more parties would pay attention to the benefits of Wide Scan; I had to argue with some otherwise decent dunes parties to let me pull when I was there as RNG main and as WAR/RNG. Maybe it's something about being tarutaru female, but through Qufim a lot of parties tended to ask others to pull when I was THF or RNG (in one case, the one asked to pull had to point out that they had no ranged weapons and no suitable pulling JA and that they should ask me to pull). I didn't start getting much real pulling experience as THF until post-30...

(In hindsight, maybe it's the combination of 'weak' race, 'weak' job, and the fact that I didn't sub NIN, which is somehow supposed to magically make me 'better' despite offering no useful traits or spells at that level...)
