So I reached level 100 yesterday with my Necromancer yesterday! I doubt if I will do that again with one of my other chars, the Necro is IMO the most fun class. I definitely will go on playing my Necro to see what what the soulcrafting thing is all about. Only thing I know is that I can soulcraft legendary items with an angelic soul after upgrading the lower ones. Is there anything else that can be done with these souls before they reach angelic status?
The question for me now is: what do I do now with my beautiful level 100 Xanthara?
Oh, and one strange thing: My pet (Dark Zealot) is literally indestructible, it never loses any HP. Bug or feature? All my other pets get hurt a lot and constantly flee.
Farm DK Trash mobs (First raid) for Skulls that you will need (such as the +HP skull and +Damage Reduction skull)
Farm the Gold Mine for gold so you can buy the Unique items you want from Table Mountains Vendor, and so you can enchant your items (sells all the Uniques that can drop, just reroll the world to refresh the vendors inventory), you should aim for 14-15k HP and 75% Damage Reduction (75% is the cap, cant get more than that)
After you have obtained those goals, it is a straight up boss farm fest
get the items you want, and Soulforge them x2, and when you are done with that you can move on to T1, Darknessfalls (oo spooky!)
You can farm Or'ak Pass/Basin if you want a few of the Legendary skulls there before you head over to DarknessFalls, will give you better stats since the Legendary skulls are better, heres info on the T0.5 Legendary skulls: http://forums.synergiesmod.com/index.php?topic=4909.0
EDIT: Can kill T1 bosses with vendor Uniques ofc, will just take you more deaths and way more time to finish a boss fight with vendor Uniques in Darknessfalls.
