Welcome to Dunehelm's Guide to Arch-Types in Oblivion
Arch-Types is basicly stuff like "Warrior" or "Mage"
Warrior(Heavy Armor) A Shield enchanted with Reflect Damage, even if your a two-handed person, the enchantment still applies, A Cuirass that fortifys your Strength. Greaves that fortify Fatigue. Gauntlets that fortify your preferd weapon style. and Boots with Water Walking.
As for Weapons, I recommend any weapon that has Shock Damage on it at least. Beacause very few enemies have a Shock resistance, even fewer in the early parts of the game. Later in the game I recommend any weapon with Paralysis, Such as Volendrung. Another option can be Absorb Fatigue or Health if your low on potions or don't have alot of healing spells.
Warrior(Light Armor) Everything above but in Light Armor, However for a Cuirass I recommend something like a Weapon Ward Cuirass or anything that Resists Normal Weapons, or Reflects Damage.
After more In-Game Tests I'll be back to finish the Guide
