New to game and Necro
Realistically, any stats work, but you want to try and focus between either Power or Condition damage. Find out which you like the idea of more, then work toward that.
That depends on your build and weapons. I’m new to GW2 too, but
I’ve read in this forum that Power is better than condition for leveling.
My necro is lvl 25 and I’m focusing on power itens. Bring a Staff too. You can equip the staff, apply your conditions and then swap to Axe for raw damage. When the staff spells get out of cooldown, swap, use them, swap again and repeat.
When you reach level 80, then you need to choose what you really want to focus, condition or power damage, but for leveling, it is not that important.
I highly recommend trying to make a condition based minion master. A lot of players don’t like them but I have found it to be one of my most powerful characters I have. I can also go AFK anywhere and come back still alive which in my book is a plus.
Sounds like a casual PvE Open World build.
Look for power gear “mighty” or “berzerker.”.
But realistically save your money, and use whatever is available from drops or karma vendors (dont hoard your karma).
