Right. Firstly, you get 4 items to start with, in the following brackets. 0 materials, up to 10, up to 20, and unlimited.
If you want a cheap and useful weapon, you’re probably looking at either the Apprenctices Blade or the Biting Blade, maybe the Triumphant Blade (at 0, 7 and 14 mats respectively).
The low level wands, staves and rods are also likely to be popular.
The trouble is, that as a lot of the effects are mirrored by skills or other, ti’s quite difficult to tell when someone’s using a weapon ability or their own… so I can’t tell you what the most popular or common is…
As a general rule, there will be more warriors than physicks, or mages, on the field. So making low level martial stuff will almost garauntee you a market.
Greensteel Braclets, Oakheart Shield, Mithril Shirt, Warriors Plate, those weapons above… you could sell those almost indefinately.
What I would suggest though, is the following.
For your 0 mat slot, pick something popular. Warriors Plate is a classic, but if you can make some of the magic stuff you’ll have a smaller and hungrier market to aim at.
For your =>10 slot, get something for you. An item that will help your character do stuff. This one you can replace easily, and reccomend it to people, and make one or two for them over the year.
For your =>20 slot, something a little fancier. Either what you may consider to be your primary armament, or something for your group or group leader.
For you Unlimited slot, something impressive. Something that you could spend a year picking up materials towards, and make maybe once a year, if that, presenting it to the owner with due ceremony and decoration.
My last character was a Dawnish fighter type, sword and shield. And an Artisan. He took:
Warriors Plate (for making when low on materials, sold well)
Mithril Shirt (he wore medium armour, this he used a lot, and sold on a few sets)
Oakheart Shield (also used himself, made a few for friends and allies)
Shieldbreaker (never got to make this in 4 years of play. Was commisioned to do make one, but died before doing so)
As I recall, 3 seasons a year he made Mithril shirt, Oakheart shield, and Artisans Oil. The 4th season, unable to get the mats, he made a Warriors Plate and a Mithril shirt. On average.
Bear in mind that characters die, artisans die, and 99.9% of items last only 1 year anyway. So there’s often substantial turnover and constant demand, even for the low level stuff.
Heck, especially for the low level stuff. Winterborn Warmail may only be worn by wealthy group leaders, but every starting character can afford Warriors Plate…
Hope that helps.
