This method isn't likely for everyone. To maximize effectiveness requires spending some DDO points. Still, it can be done without. You'll just use a lot more Cannith Essences. This approach takes a lot of the pain and repetition out of leveling Cannith Crafting skill.
Note that while this post covers the same ground with largely the same approach as Tols' "Cannith crafting leveling plan" ( https://www.ddo.com/forums/showthrea...-leveling-plan ), it's somewhat less technical and possibly slightly more approachable. Still, if you want additional details, check out that post as well.
Background:
--------------
The best crafting XP comes from crafting the lowest-success-rate shards. A single shard can propel you through multiple levels when your crafting level is low. Even when your crafting level starts to get quite high, it only takes a few shards to level up if you take this approach. This system requires at most only three things: Crafting XP bonus elixirs (CXP pots), Crafting Success Boosters (CSB), and Cannith Essences. This method is specifically aimed to get your crafting skill high enough to craft any bound shard. Beyond that, it might require tweaking and/or additional resources.
First, maximize the crafting XP you get for each shard:
-------------------------------------------------------------
Pick a 'Double crafting XP weekend'.
Use Crafting XP bonus elixirs (you won't need many: really only 1 or 2 if you do this at one sitting). You can buy CXP pots in the DDO Store (up to +100% CXP for 30min), but you can also earn one Greater Crafting XP Elixir (+75% CXP for 30min) each life by simply running the Cannith Crafting Tutorial in House K (It's not available in the House C crafting hall for some reason). 50 House C Favor will allow you to buy 10%/30min CXP pots, but unless you're under time pressure, I'd skip them. More XP per success means crafting fewer shards and using (far) fewer essences..
Second, maximize your crafting success:
---------------------------------------------
There's only one way to do this of which I'm aware: Crafting Success Boosters. You can buy 10% CSBs from the House C Patron if you have 50 House C Favor, but again, this isn't ideal. The Cannith Crafting Tutorial will allow you to select x5 25% CSBs as your reward in lieu of a CXP elixir. However, for best results, x25 35% CSBs from the DDO Store are ideal. Again, higher success rate = fewer attempts and less resource use. You can also use a combined approach. Use 25% success boosters at lower levels where the number of essences/shard are low and switch to 35% boosters as the amount of essences on the line increases.
Artificer crafting bonuses DO NOT help:
-----------------------------------------
From DDOWiki:
"Artificer Craft Mastery
This feat grants you a +1 bonus to all of your Crafting Levels for every second (even) Artificer level you posses.
Your crafting level is first calculated based on what your current experience total would put you at, then the Artificer bonus levels are added. This means you save dramatically on leveling costs and time, particularly at higher crafting levels."
All this does is treat you as though you have more CXP than you actually do, making it more expensive in materials because you're crafting higher-level shards. At the same success chance, you get the same CXP.
Methodology:
---------------
1. Make sure it's a Double Crafting XP weekend.
2. Activate your preferred CXP pot.
3. Craft ONLY Minimum Level shards. This limits your required resources to the CXP and CSBs listed above and Cannith Essences (at least with regard to the crafting levels under consideration.. say up to 320 or so).
4. Craft the shard that has the lowest success chance. At any given Crafting Level, there'll be a ML shard with a 3% or 4% success chance. Successfully crafting this shard will give you a huge pile of CXP (details follow).
5. Put the highest value Crafting Success Booster you can acquire into the Booster slot. If (as recommended) you use a 35% Booster, this will raise a 3% success rate to 38%. On average, you'll craft a shard every third try (ballpark). If you use a 25% booster, your success rate will be 28% and you'll use considerably more Cannith Essences. If not spending DDO Points is sufficiently important to you, this may be preferred.
6. IMPORTANT: Between shards, close and re-open the shard workshop window. This will refresh the listed success rates. They do not update themselves when you gain one (or more) crafting levels.
7. Repeat until you run out of boosters or essences, or attain the highest crafting level supported by this approach (somewhere between 320-340).
Results:
---------
Given a double crafting XP weekend and a decent CXP elixir, each shard should net you around 3K CXP. (This is based on my memory of having done this some while ago and idr what CXP elixir I was using.. probably the +75%).
A crafting level around 300-310 will allow you to successfully craft pretty much anything for your own toons (i.e. every bound shard). You'll know your crafting level is high enough when you can craft ML34 shards at a decent success rate.
This will require approximately 350K-400K CXP total, or about 120-130 successful shards crafted (out of around 300-400 attempts if you're using 35% Crafting Success Boosters; if you're using 25% Boosters, it would be somewhat more. It will also use up a ton of essences (though fewer than other methods). I'd estimate you'll probably use in the neighborhood of 60K-100K Cannith Essences. Regrettably, idr how many I used, and my estimate is based on an average of around 200-250/shard. In reality, a bound ML shard uses MLx10 essences. However, since at the lower levels it takes fewer shards to level, the average number of essences/shard will be on the high side.
Using this method, I leveled from Crafting Level 30 to 326 in a single day on one of my toons. Unless you intend to craft items for sale or for friends, this crafting level is all you'll ever require (at least unless/until they change the system). As a bonus, the only side-effect produced will be a series of ML shards, of which the majority will tend to be of higher levels (at lower levels, one shard may gain you more than one crafting level whereas at higher levels, more than one shard will need to be crafted per level). At most you'll have 34 stacks of shards of various MLs, which means not much storage wasted. And ML shards are inherently useful, so there's unlikely to be a need to deconstruct them for 10% of the essences used to craft them. Simply save until needed.
