Is it possible to successfully play Skyrim as a pure tank type fighter?
Haha, yeah dude. My main is a jack-of-all trades, but initially was a tank.
Orc, smithing, enchanting, alchemy, heavy armor, one handed, and blocking. Leveled up only health the entire game.
Eventually I had extra perks to spend, so I used them on archery and sneak, but that's only an afterthought. Now he can do anything. What about magic? Well I could enchant some armor to reduce a schools cost by 100%, or use the staffs or scrolls I collect. The only thing he can't do is pickpocketing.
I use ebony mail and the spell breaker so I can sneak silently in heavy armor, and block spells. The Lord's stone helped at first, but I now use the atronach to I can absorb spells. Unstoppable even on master.
