Wowhead search gives the expected answer of 65.

My experience so far is, no level requirement for gathering professions, level 65 for manufacturing professions. Both require 350 skill to train up.

I checked mining, herbalism, alchemy, blacksmithing, engineering, tailoring, enchanting, and inscription so far. I'll try to remember to check skinning, leatherworking and jewelcrafting when the servers come back up. (They're down for a new push right now.)

Also of note, some individual recipes have level requirements to learn to craft them now, which I'm not certain I've seen before. Northrend Alchemy Research requires I think alchemy 400 and level 75 before you can learn it. Minor inscription research takes inscription 90 and level 75 before you can learn it, but I suspect that's a bug -- there's also a higher-level Northrend Inscription Research that also takes level 75 (but skill somewhere around 400).

I have been searching for this information and haven't found any reliable data. I am trying to determine what level of skill will be required to DE items from Northrend. This is valuable information for those of us with enchanter alts whom we don't necessarily want to max to 375 prior to WotLK.

Answered my own question.

1. Round the item level up to the nearest 5th. This creates 2
brackets for DEing greens from Northrend, level 71-75 items (round up
to 75), and 76-80 items (round up to 80).

2. Multiply that number by 5. For level 71-75 items, this result is
375. For level 76-80 items, this result is 400.

3. Subtract 75 from that number, resulting in the minimum enchanting
level required to DE that item. For level 71-75 items, this is 300
enchanting, meaning you'll need to have at least a level 35 character
to DE. For level 76-80 items, you will need 325 enchanting, which
means you will need to have at least a level 50 character.

Handful of crafting changes in patch 9014:

-- The Blacksmithing socketing ability for Bracers and Gloves now reads: "Permanently add a socket to your bracers. Requires a level 60 or higher item. Cannot add more than one socket to an item. Can only add a socket to your own armor, and adding a socket binds the item to you. The added socket requires that you maintain 400 blacksmithing or it will become inactive."

-- Enchant Weapon - Greater Savagery - Now only works on two-handed weapons.

-- Titanium Weapon Chain - Changed from minimum level 70 to 60, and the description clarified to list it as making the item soulbound.

-- The Inscription-only shoulder buffs were given a minimum level of 60.

I take it you mean required level, not item level. For example, the lowest level Northrend greens require level 67, but are ilvl 130.

Also, did you get these numbers ingame? According to WoWHead, the lowest level greens require 325 enchanting skill to DE, while the strongest take 350. Oddly, all blues seem to require only 325, and epics 375.

Fun.

Darkmoon Card of the North - Spell - World of Warcraft will craft Northrend Darkmoon Cards.
Greater Darkmoon Card - Spell - World of Warcraft makes Outland cards.
Darkmoon Card - Spell - World of Warcraft makes pre-TBC cards.

No idea if an Ace can be crafted in this way.

edit: Doublepost

My beta inscriber has an Ace of Warlords sitting in her bank, crafted this way.

Darkmoon Card - Spell - World of Warcraft
In the comments, someone remarked they crafted an Ace of Beasts. I made 6 Darkmoon cards or so on the PTR, I just didn't happen to make one myself.

The beasts (mana regen) and portals (chance to rez) decks are obviously still quite useful at 80, regardless of level. Could be a nice money maker, and will be nice to have the rez deck be reasonably easy to acquire, just for the sake of saving time.

I wore the Portals deck for some 2 months, back in the days while raiding MC and BWL, and it just wasn't worth it, i got the very hefty amount of one Proc and that is when i put it into the bank and regretted the money i had put into it.
And now that everybody gets to ressurect somebody it's even more worthless and definately not worth wasting a trinketslot.

*edit yeah that post was horrible, my bad.Hope it's better now.

Obviously depends what content you're doing. If you're just farming then you'll likely use no more than 2 per hour, but if you're trying to progress past a boss it can take many more than that. I've personally used over 20 [Blackened Basilisk] over a 4-hour period of M'uru attempts.

A few of my guildies put in suggestion tickets to blizzard that they consider raising the amount of spices, pointing out that there is a stark difference in consumable usage for raiders when farming content or progressing. I don't think Blizzard intended to limit the number of times you could be all you could be via a mechanic like that.

As of last night's build, the level 75 requirement for lesser inscription research has been lowered. I don't know if it was completely eliminated or reduced to a lower level, but my level 70 Death Knight was finally able to learn it. The old requirement was level 75 and inscription 90.

The ability has a 20 hour cooldown, and gives you a new lesser glyph. The materials are dirt cheap. My first attempt at it yielded the glyph of water walking, which allows the shaman water walking spell to be cast without a reagent.

In addition, glyph slots on a charcter don't open up as quickly. The third major glyph slot doesn't open until 80th level. I believe the third minor glyph slot doesn't open until 70th also.

I already had the ability on my Death Knight on the beta, it was bugged last patch so it's cooldown reset after relogging, so I got to do it a lot. It seems to be skill based which Minor Glyphs you can learn from it at least: I mostly got minor glyphs that were gray to me for skill ups, and which required various inks made from pigments from Azeroth herbs. I had one or two glyphs however that did give skill ups, and required Outland herbs. This was at ~300 skill.

It also seems that it's basically certain that you'll learn at least one Minor Glypy as long as you have one you can still learn. I used the ability 50 times and learned a new Minor Glyph every single time.

The scrolls produced are the second version of each of the stat scrolls, the two lowest level enchant storing scrolls, or the lowest level scroll of recall. You get one to two of one of those each time you use Minor Inscription Research. Not particularly useful for a high level character, but possibly a nice bonus if you're actually levelling a completely new (non-Death Knight) character with Inscription.

Thank you for mentioning this -- it turns out the current build still has this behavior.

I'm not certain it's a bug -- it could very well be intentional during beta to facilitate testing. Later today I'll see if it also applies to other tradeskill cooldowns (alchemy transmutes, primal mooncloth, and anything else I can find).

(If so, I really want to push my alchemist to 75 soon, since that level is required for "Northrend Alchemy Research". I should hit 74 tonight, and finally see Dalaran...)

It could also be explicit code added to the logout hooks to reset cooldowns -- this way, we can do accelerated testing and we can also test LUA code that interacts with realistic cooldowns (eg. for trade cooldown mod authors). I don't know enough about their internal codebase to judge how likely that is versus "it's a bug". They very much are deliberately accelerating all sorts of things, like how often Wintergrasp goes uncontrolled and when raids reset, to help with testing, but they also very much are still producing bugs.

In either event, the right course of action is for me to do more testing and then /bug the issue, and I'll do that this evening and report back here.

Suppose you raid 5 x 5 hours a week. The duration on food buffs has been raised to 1 hour so farming is 5 buffs, suppose progressing is 30 buffs then if you spend 2 farming, and 3 progressing that is 100. at 7 x 13 Northern spices a day you are pretty close to being able to do that yourself. If not I'm sure food buffs will show up on the AH which I suspect is probably what Blizzard intends. I can't imagine anyone who is serious won't have enough food buffs.

I think this possibly caused a bug of sorts for beta (something that wouldn't affect live). I'm still only L70 on beta but had glyphs in all 3 major slots. After the patch I could destroy the remaining 2 major glyphs but could not add new major glyphs at all. I didn't have any minor glyphs to test with. Recieved no error message (made sure I was standing on the lexicon, relogged, restarted etc.) and nothing worked.

If it's still busted tonight I'll submit a bug report.

(I fail at math. Delete.)

Make it half an hour in length but persist through death, like a flask, perhaps?

Alternatively a raid could pool their spices and make a Fish Feast for the raid. Obviously not the perfect food for everyone, but if its used by more than 4 people you come out ahead on spices. Also takes 6 fish per feast, but again thats a thing you can spread out.
