I can understand if you wanted to exploit on a weapon. However, using the exploit on armour is foolish, as it could be 1million armour and it would do the same as one at the cap.
I personally would suggest a sneak archer for master. At least as the best chance to survive. An assassin with decent stealth and the bonuses from the perks has a better chance of killing and surviving. Just play smart and run away when you have to. I am even thinking about running a character on master like this just for a bit of fun.
Right now I am running a 2h orc warrior. Had originally thought not to even touch enchanting, just do smithing heavy armour and 2h skills. However when reading up on the Orcs they are into enchanting their items, so I have started working on that. Right now he uses dwaven hammer and orcish armour. Tried doing archery a bit with him but his damage out put sux so badly I just tossed all my archery gear to my follower. Though I am gonna kick her to the curb shortly to do some heavy armour leveling. It don't work too well when she kills them while I am sitting there letting them beat me up. LOL
Oh that being said, I first tried sneak with follower, but found they absolutely SUCK for a sneak. So if you were going to play a sneak on ANY level I would say kiss the follower good bye.
I understand that exploiting armor to thousands is just a waste and most likely just going to cause glitching, i just want to cap my heavy imperial armor TO the cap (or as close over as i can get, because i doubt i can get it perfect) because i plan on keeping that armor throughout this whole playthrough. I don't want to exploit a weapon because the only reason i'm switching to master is to give myself a channenge. If i made a weapon that could kill everything in one hit even on master, that would defeat my pupose.
I was thinking a sneak archer because i love them, that's what more than half of my characters are, but i was worried that i'd be way too underpowered in lower levels, and end up just pissing the baddies off and getting dominated because i can't hold my own. Maybe i'll try one next, after i get the hang of the enemies being so tough, but for now i thought a sword nd board was the safest. not to mention it fits my rp
As for a sneak character with a follower, i've had a couple that were decent (aela and janessa) but usually roll without them. There's several sites you can go to where they have all of the followers skill levels, and ssome of them have pretty high sneak. That said, i have no idea what aela's or janessa's sneak levels were, i just noticed that they didn't make me stand out as much and make it impossible to sneak effectively.
