Rejecting

Shane was overjoyed to see that he was already able to pick a [Platinum] quality occupation, and he was immediately curious to take a look.

However, when he did look at the catalog, he sewed his mouth shut in order to prevent himself from exclaiming loudly.

"Thousand dimension….merchant?!? What is this bullshit!!!" Seeing the [Thousand dimension Merchant (Platinum)], Shane was rendered speechless for a moment, but it was obvious that the platinum occupation in front of him was not a combat-oriented occupation.

Even if it would most likely benefit him a lot, like amplifying his memory capacity or other aspects that were important for a merchant, it wouldn't really amplify his strength or combat prowess per se.

The only thing that might work is that a platinum-quality merchant occupation might even amplify his intelligence by refining his brain, but it was still unclear.
