Dead is Dead. (DiD) Turn off autosave, and don't hard save unless you're taking a break. Delete save files as you reload them, if you die, you go straight back to Helgen. I highly recommend Orc, Shield, and a backup bow (A good one.)
Warrior is still the easiest way to go. All weapon skills, the best armor, shields, and smithing will beat anything in the game, on master, not even all that hard. Mage is tricky, Pure Thief is basically limited to avoiding all combat. You can't even backstab without 1 handed.Stick only to one of three play styles: Thief, Mage and Warrior. Meaning only use perks for those skill trees, so a thief would not use any one-handed or archery perks.
Turn your hud to 0%, master difficulty, have to eat three times a day and sleep once a day. Carry no more than 20-30 arrows, Limit carry weight, no crafting or enchanting, and start the game with no items but the ragged robes.
Like using no skills whatsoever.Sure there are harder ways,
Without skills, or leveling. I've beaten it with a level 1 Kajiit, I don't mean don't hit the level button, and assign points, but not gaining any experience at all throughout. Unarmed, unarmored, no lockpicking, spellcasting, nor crafting. I had to do it on Novice, though. Scrolls, and Staffs are extremely helpful, but you can't recharge them without earning Enchantment experience.
