Where in chapter 2 can I find any of those ? If I can't, then where in chapter 3? I think I need one or two more to get the "experienced" perk.

I'm with Vergen, and won't be friendly with the knights in chapter 3.. I wonder if it's instant death walking into their camp, or even if you can do that (in search of those t.d.).

Sorry, I haven't been able to find an answer anywhere on this topic.

Btw, I can't afford to get killed, since I am doing the game on "impossible" :D (3rd playthrough).

According to the Wiki, there are no training dummies at all in Chapter 2, but there are two of them in the Temerian Quarter, and two of them in the Order's outpost, in Chapter 3. Unless you sided with Siegfried in TW1, I don't think you'll be able to enter either area safely if you've gone down the Iorveth path in Chapter 2.

If you enter either camp - and they're hostile - it doesn't mean an instant death, but the Order will infinitely respawn, and if you kill more than one guard in the Temerian camp, I think you'll be thrown in jail; so the latter might be an idea. Once you're ready to progress with the story there, rush in and try to get the training dummies as quickly as possible, and then let the guards capture you if you can't make it back out in one piece.

I see.. :) thx

Regardless, playing vergen's side nets you full level 35 by the end of the game, although you benefit from it later on. So, now I would take the ability in case I will import my game for the expansion xD It would be awesome.

I guess not having the experienced perk puts you 1 level behind around levels 25-30, meaning you have to play with one less talent point. In any case, you finish at max level playing Vergen's side.

Yes, and in case you don't know, the perk apparently works retroactively, as well. :)
