3. I want to say... No. Siege is very community focused, and there are already a TON of crafters. Now, if you're looking to fully support yourself and live like a recluse. Then, sure. Make a crafter. If I were you, I'd invest on skills that can bring in cash/loot and buy/trade for your imbued gear. Crafting simply won't make you a living (unless your Magichands)
LOL asty ! Well i know that can sound strange but i farm me too a lot of PVM to make some money !
- I have never had a character on Siege so I will be starting from scratch. I am guessing that hiding and stealth are a must for newer players?
- I want to start out with crafting and gathering skills on this character. I know EJ really limits what can be done. Gathering is limited to the basics, what about crafting? Will I have access to all the common recipes or will that be limited as well?
- Are crafters viable on Siege?
First welcome ! Don't be scared to try Siege... It can be hard but if you are looking for the old spirit of UO probaby this shard is the one that go nearest to the old UO !
As said by the other players, it's true being a crafter on Siege is not a fast way to make money. But all depends what are you looking for... If you plans to play just to have fun, make friends, being a part of the comunity and help others players, being a crafter give a lot of satisfaction. But keep in mind that the market is very full at the moment so probably you have to focus on something special and for a new player that can be really hard. As suggested by others, probably a PVM char with crafting skill can be a good idea. You can farm resources and ingredients you need and in the same time you can make your own suits.
If you want start as crafter, keep in mind that here you cannot sell anything to vendor so probably it's better starting with mining and tinkering so you can make your own tools and then you can train all other skills like blacksmith, tailoring, carpentry, fletching, alchemy, cooking or inscription. Imbuing is another skill very useful to train and if you have already blacksmith or tailoring, that can help you a bit to train without hunting for get items to unravel.
Remember that Arms Lore is a must for the bonus to resistance or damage increase on what you craft. So as you see probably you will need a bit of Soulstones.
Hiding and Stealth they can help you to recover your gear when you die from monsters or if you are lucky to run away from pks (if you see them in time, thing that don't happen often till you have them in front of you

).
So it's a your choice

When i started here on Siege i made a mystic mage with stealth and hiding and i have to say wasn't too bad but there are a lot of template that are very nice and on discord there are many guides write very well by Max

But as first thing join NEW, that will make your life easier in first period !
See you soon in game and welcome again !
