I'm very much a noob and still trying to grasp all options in the game, so bear over with me.
Question 1 - generel:
Do you have any generel suggestions on how I can or how I should optimize my current profile? Perhaps even some "low hanging fruits" that i've missed.
Question 2 - rerolling properties:
I probably don't entirely understand the reroll concept yet, but i've understood that I can reroll a property to something else.
I currently have a few different items that "should" be a part of the build, however one big minus is that they don't have any sockets.
Am I actually able to reroll a socket into either my BK swords, or the following rings/amulets that I have?
Question 3 - blood shards
I've currently had no luck finding: Pride of Cassius - can I actually gamble for that item?
Question 4 - follower
As for my follower, im not sure which way to go. Currently using a templar with whatever "good" items I have. However not sure if I should use another follower or whatnot.
Zodiac: reroll resource cost to socket and equip
Unity: no use for that item
Skull Grasp: put it into your kanais cube
Maras: as soon as you've got your 3rd legendary gem on 25, reroll to socket and put it in.
Eye of Etlich: reroll resource cost if you are planning on wearing it.
The best possible neck for you is a Hellfire Amulet.
Regarding Blood Shards: yes you can get pride of cassius from kadala. Just keep spending shards.
