Step 1: Forget everything you know about how to make builds in every other ARPG.
Step 2: Make a list of the known Bugs in game. (WARNING: You may not have enough space on your hard drive to save this massive file)
Step 3: Scour every website, social media, Discord server and/or Guild chat to learn every detail of said bugs so that you can exploit them.
Step 4: Now that you know which Uniques, Aspects, and paragon nodes are either stupidly overpowered or DON’T WORK AT ALL due to bugs you may proceed with regular build creation techniques.
These steps are most crucial for the Necromancer class as almost every single build to ever exist for this class have relied on bugs to do damage. Spiritborn is working very hard to overtake this #1 spot.
If you have any questions, just look to the BUGS!
