Just curious what enchantments everyone puts on their armors, and weapons

Do you switch out sets of armor often?

I switch armour sets a lot. My characters have different armour for different scenarios. Like a battlemage armour set with a balance between magic and combat enchantments for example.

As for weapons, it depends. Nordic or Stalhrim always gets Ice, while anything else tends to get Lightening.

Really only depends on what kind of character I'm playing. My mages always use enchantments to boost their magika and magika regen. My assassins use anything to boost sneak, archery and one handed.

Can't go too far wrong with firey soul trap, I always find. Nice to have a shock-enchanted bow on hand as well for fire breathing dragons/Dunmer/mages, too. Absorb health and/or stamina can be a life saver on melee weapons. I quite like having a health and/or magicka boost on my gear, and possibly some extra sneak or armour boosts, and/or magic resistance. I sometimes end up with six or seven different sets, most of which stay at home in a chest while I go everywhere in my bog standard (legendary) red vampire armour with a bit of a destruction/regen boost and a circlet 'helm' or mage hood. Current character needs to work on her enchantment a bit, I think, she's currently got pretty much no enchanted gear except for a ring and a necklace, although I'm using SkyRe so she can put temporary enhancements on her sword with an Alteration spell (need to remember to buy a couple more spells next time she's in a city.)

For my mage character i use clotes enchanted this way:

Hood: Fortify Destruction + Fortify Alteration

Robe: Fortify Alteration + Fortify Illusion

Gloves: Increase magika + Carry weight

Boots: Muffle + Carry weight

Necklace: Fortify Destruction + Fortify Illusion

Ring: Fortify Destruction + Fortify Alteration

I use Alteration and Destruction as main spells (0 cost) and Illusion and Restoration as back-up.

I only carry one dagger enchanted with Fiery soul trap and absorb health (i have low carry weight, even with 2 items enchanted)

For my warrior character i use heavy armor, war axe+sword enchanted this way:

Helm: Waterbreathing + Fortify Destruction

Armor: Increase health + Fortify Destruction

Gloves: Fortify One-Handed + Fortify Carry weight

Boots: Fortify One-Handed + Fortify Stamina regen

Necklace: Fortify One-Handed + Fortify Healing rate

Ring: Fortify One-Handed + Increase Stamina

Sword: Fiery soul trap + Absorb Health

War axe: Absorb health + Absorb Stamina

With Fortify Destruction over 90%, i don't have to recharge the weapons for months (unless i lvl up my enchanting skill - legendary)

My current character, Oden Krios is a Nord and is still relatively weak. The only enchantments he is currently wearing are,

Steel Armor of the Knight - Foritfy Heavy Armor by 15 points

Steel Bracers of Skill - Fortify One Handed by 10 points

Steel Shield - Fortify Block by 10 points.

Ancient Nord Helmet - Foritfy Heavy Armor by 10 points.

My Dwarf gets Health/stamina bonuses with magic resist mixed in. On his weapon he will get Life drain on one and Lightning on the other.

Which enchantment depends on the character. I'm very bad with soultrap spells so my mages tend to have daggers with soultrap. My warriors usually have either fire or lightning, sometimes just to name the sword.

My non-enchanting battlemage ( only one craft and I chose smithing) enchanted her husbands sword " Vorstag's wedding present",

Well, it depends on what kind of character I play. For armor, it ranges between Elemental Resistance to increased Heavy/Light armor to Combat Skill. For weapons, there's usually only 1 certain that's almost on every character. Dual Enchmantments with one of the weapons having Soul Trap. At least one weapon with every character. I do hate using Conjuration.

I like absorb stamina on weapons. Power attacks for days.

Muffle or fortify carry weight on boots (muffle for followers).
Then I usually focus on fortify health, magicka (if I use magic) and resist enchantments for the rest of my gear. Same for followers.
For weapons, I'm fond of absob health, paralyze and fire enchantments.

Current character isn't using enchanting, so for her I'll be stuck with what I can find.

For combat, I go mostly with Resist Frost wherever I can on the armor, and Fire Damage on the weapon.

End-game, I go for Fortify Destruction+Restoration, then go riding dragons forever.

Don't forget enchantments on clothes / robes and staffs. Enchanting is primarily a mage school
