I know there's at least three ways to reach the Bandit Camp in Chapter 3:
- Make Teven in Larswood recruit you
- Make Raiken in Peldvale recruit you
- Kill 'em all and just march in like a champ
From memory, I thought there was a hefty XP bonus when you successfully infiltrate, but I got a mere 400 by convincing Teven and then Tazok, all without a fight. Dunno if they patched it or if my memory was just wrong. Doing the same with Raiken also gave the same amount of XP.
When you use either of the two to infiltrate the camp, the other one disappears and can't be fought. (The one you used will be in the camp so you can still fight him.)
Teven gives 900 XP and Raiken 650 XP. This means that by taking the 400 XP by infiltrating, you're making a net loss of 500 or 250. Given that, is there any incentive to infiltrate the camp instead of just killing Teven and Raiken and doing a full frontal assault?
I simply don't see any reason other than RP purposes to infiltrate. It allows you to talk to some NPCs and get extra journal entries but none of it seems to give any XP or such. You can't avoid fighting the whole camp either; you need to enter the big/main tent to progress the story, which initiates a fight, and when you go back outside you also get attacked.
OK, there's one marginal benefit I can see: you can open all kinds of chests beforehand so the potions and scrolls you find within may help you with the battle. But that's a really minor thing.
Am I missing anything?
