This build is meant to be well-rounded and especially so when it comes to gear. This build will give you some chance at survivability during PVP activities as well as ability to support your team in PVP. You can quickly swap between 3 different skill builds - I recommend a build for general activities and focused on AOE (such as this skill build), another build for dungeons and single-target dps, and a third build for PVP (or if not PVP then a very heal focused skill build).
The sophia set is very easy to obtain - you receive the ring from the MSQ (main story), the necklace from Syleus's Abyss 1F-2F Exploration quests, & the bracelet from Temple of Sylaveth Exploration quest. You can complete the Syleuss's Abyss and Temply of Sylaveth quests in 20-30 minutes especially if you have a friend to do it with. If you didn't get the Sophia ring during the MSQ you can get the Robert's or Rutaine's set from these quests. Just make sure you get all 3 matching set pieces - I don't believe there is any other way to obtain them in the game so if you screw it up then you won't be able to obtain the set.
