What gear should I be looking for?

Depends on budget. So it looks like you want to PvP, that rules out the cheap option of morai.

This is likely to be your goal.

After that, you want to fix that terrible pdef with a cube necklace and warsong belt and refine these to +10. Then, you refine the rest of your gears to +7 and your weapon to +10 to +12.
You are now the standard mid class wizzard.

If you want to be end game, you go for r9.3. This however requires you to farm/merchant/CS 2000 gold or 3 billion coins to get the gear alone. Then you need an equal amount of money to refine it and once more the same amount to shard it.

The build i gave you might look a long way from where you are. Google the items so you find them in the database. Then you can see the recipe they are made from. It is a series of items all the way down to TT70. You keep upgrading your items till you are at the G16 i posted. So just follow the line up there.

TT90-TT99gold-NirvanaG13-NirvanaG15-NirvanaG16.

If you do this, the equipment will be bound to your character. This means you cannot trade it with other players. You can however put it on an account stash and use it on different characters you may create on your account in the future.
If you want your items to be fully tradable, you need to go a different path. This is the lunar path. It will result in tradable nirvana G16 items, but it is a little harder to get. When you go google and find the items in the itemdatabase, you should discover that there are different recipes that make this G16 stuff. One is comming from TT, the other from lunar. Take your time to explore this.

Note that the gap in cost or hard to farm items is from TT90 where you are now to TT99 gold. (or the equivalent in lunar equipment) So you might despair while you are trying to make this upgrade and logically expect it to get harder and harder to upgrade, but this is not the case. Since it will be rather impossible for a TT90 wizzard to farm the needed TTgold items in TT3-x, you will need to buy these. So find other means to make money for this. You will need something like 200million total to make these TT99gold gears.

After you got this TT99 gold, you will get to NirvanaG15 in a heartbeat. Then to get to G16 you will need to farm some warsong, so the G15 to G16 step is gonna take some time again, but not nearly as terrible as getting from TT90 to TT99.

Note that i just took a cleric build and made some minor changes to it. Possibly you want to focus some more on channeling from your rings and belt / necklace. however, don't forget that these are your only source of physical defence.

yes, i like the suggestion to make a farming alt. Because really the wizzard alone is gonna have a hard time. There are different sources of income. In order of effectiveness:

1) Cash shop
2) APS farming
3) Merchanting
4) Dayly BH and Cube on multiple characters
5) Different farming

Since 1 is not to everyones liking, 2 requires a completely different character with completely different gear costing you 500million, 3 may or may not be one of your tallents, many players end up relying mostly on 4. Thats why it is usefull to get more than 1 or 2 characters to lvl 100. This will help you reach the gear level i posted in the first reply.

If you want to be what the above poster calls "competetive" (and i pretty much agree with his definition) you will not get there with only methods 4 and 5. Many players get there with a combination of 2, 3 and 4. Some include method 1. If you want to go there, get an APS farmer rather sooner than later and get ready to farm 10 hours a day while your catshop is doing the merchanting on a second account. In this case skip the whole G16 nirvana build. You will need R9, but your primary goals are to get that aps farmer and build a trading capital.

If you are happy with the not so competetive mid-class build i posted, then yes, a few months of method 5, 4 and maybe a little 3 should do the job.

Another option i did not cover is r8. If you plan to eventually go r9, this is probably a reasonable route since you will need the reputation anyway. If not, the quality/cost ratio is probably not really worth it compared to the G16.

You need r9rr to really be competitive.. but 3rd nv isn't a bad second choice if you are short on coin. One thing that makes me want to punch a baby is when I see people getting "end game" gear (3rd nv/r9rr) and then considering +5 refines end game. Refines/shards give you way more bang for your buck than the actual gear does.. so allocating 90% of your available coin to obtaining the gear and then not having enough refine above +5 is dumb. I think you'd be nuts to shoot for anything below full +8.. (and preferably +10), but that's just my opinion.

I largely took the build that Hruns made, but edited it slightly.

The ring offers almost as much as the +6 phys one (literally 21 fewer pdef per) but gives more magic attack and allows for channeling. I also would recommend looking at demon heart necklace as an intermediate step for cube neck instead, it's cheeper (at least on Sanctuary, I can't speak to the price of the mats on Archosaur) and since the goal should be a Cube neck, that's a much better option in my opinion.

Oh so what was the question about then ?

You play 2 years, you know r9.3 is possible for you. What more to know ? If you go G15 or G16 cube with it ?
If you just wanted to complain about being one shot or whatever, maybe you could explain that you ask a question but are not really looking for an answer and people dont need to spend time on answering it.

If you're looking for intermediate steps, a cube neck would be a good start since that will increase your def by a lot, and you will need that for your end game set. Once you get to 100 you can get r8, but if r9/r9r3 are things that you anticipate getting in the nearish future I would avoid really upgrading any gear you either wouldn't be able to use on other toons or resell (IE don't go buying tt99 stuff and vanaing it and making it +7 if you are gonna turn around and get r9r3 in 6 months and you can't use it on other toons on that account, that's why lunar is an option)

How far are you, realistically, from getting r9/r9r3, because suggestions will be dependent on that. If you double your coin every rep sale and you're currently at 700m and can get it in a rep sale or two our suggestions will be inherently different from what they will be if you're at 70m and you're 2 or 3 years off.
