Hi. I am new to Grim Dawn and i started playing an Archon Guide. I don’t even know how to look up for builds and follow guides. I simply want to know how to
spend my attribute points and what kind of gear show i choose for optimal damage and defense ?
Right now you can spend a lot of attribute points in Physique for defence, and a few of them in Spirit if you want to use elemental skills (fire, lightning for example) or if you are lacking energy.
For the gear if you have enough damage you can use a 1-handed weapon + shield, but if you are lacking damage then use a 2-handed weapon while putting a lot of skill points the Primal Strike skill of the Shaman tree, it deals a good amount of damage.
Also don’t forget to spend Devotion points (you get them when cleaning or restoring Devotion Shrines that you encounter during the campaign), there is a good explanation here on Devotions: http://www.grimdawn.com/forums/showthread.php?t=56243
This last link can also be useful for you for other informations 
When you will have levelled a bit, have a look at this guide for example, it explains in details a good Archon prototype: http://www.grimdawn.com/forums/showthread.php?t=82970
The end-game equipment and skills is detailed here, but that is for later, when your character almost at maximum level: https://www.grimtools.com/calc/q2MpdRbN
