Hey
I'm sure these questions have been asked hundreds of times before but I wanted some definitive info before I use my mats and decon shedloads of gear. Let me know if I should move to another subforum!
tl;dr skip to the questions

I’m starting to pick up some decent dropped sets (blue trial stuff etc) and looking to put together some gear which will work for magicka DPS and healing, and wanted to get some confirmation/advice on improving gear.
I’m pretty happy with my crafted stuff – I’m looking to mostly use Julianos or Seducer with a dropped set. So I’ve got 1 fire & 1 lightning (no enchant), 1 resto (powered) in both sets, all gold, and 5 light pieces as well as a heavy chest and medium legs, all gold 160 divines, magicka enchant. Also a heavy chest with health enchant in case I need it. My thinking is that I can then use any combination of monster set armour weight (as long as the shoulders aren’t heavy). Probably a bit of a waste getting everything yellow but I was heavy on mats and kutas.
Then I’ll use 3 jewellery (although I usually keep 4 so I can swap in a regen if needed) and 2 light armour pieces of whichever dropped set – shoes/belt/gloves.
Is that sensible so far or am I missing something? I know it’s not BIS gear but I’m hoping it will serve all my magicka alts pretty well until I get some. It also keeps my farming process pretty straightforward, and hopefully means I can finally get rid of the thousands of dropped/monster pieces I’ve had clogging up my inventory for ages just in case I ever use them. Should also be enough to farm some decent VMA weapons without having to crawl through with 2200 spell damage!
So my questions revolve around what to do with my dropped gear. I have some normal trial gear plus sets in the above pieces for necro, war maiden, mother’s sorrow, Elf Bane, BSW, SPC etc.
1) My understanding is that if I improve dropped gear I don’t have to enchant it again – green dropped gear will become top quality gear if I improve it to yellow, without any need to use a kuta. Is that correct?
2) What does improving actually change? Is it the set bonuses or just the enchantment? For example does 5 pieces blue give the same set bonuses as 5 pieces yellow, or a mixture?
3) Let’s say I have 5 Siroria blue pieces – jewellery, belt and shoes – is there any point improving the armour to yellow? I won’t be jewellery crafting any time soon although obviously I hope to start picking up purple trial gear. I assume I'll get the better stats from the enchant, but will the set bonuses be based on the blue jewellery?
4) What enchantments should I put on my damage staves? Both infused? Or some Charged? Nirnhoned? Precise? Sharpened?
5) If I do need to enchant dropped armour (hopefully shouldn’t happen with the 5 pieces as they’re usually going to be magicka, but for example if I have purple medium monster shoulders with a stam enchant) can I “over-enchant”? So could I enchant a purple shoulder with a yellow mag glyph, or a purple head with a yellow tri-stat glyph in anticipation of improving to yellow later? Would I be able to do this, and would it give better stats to purple armour than a purple glyph?
Finally, is there an addon which would let me “group” all these pieces of gear (all monster sets, Julianos and seducer, dropped sets) and move them to the bank or into my inventory? Rather than spend 20 minutes going in between accounts every time I want to play another alt?
Cheers, sorry it's a bit long-winded!
