How to get a Synergy Crystal and what does it do

I'll try to put them in ways you'll relate to :)

Souls are unlocked as you do quests and close rifts as you level up.

Each Calling (class) has access to 9 souls (talent trees).

You can pick any 3 souls at any given time (when you've earned them all) and can swap between up to 4 different soul settings (think dual spec but with 4 slots).

Recommendations are usually not suggested as an answer on these boards. But to give you a little direction, a hunter (which I also played :D) is in the rogue calling, and a shaman is more of a cleric calling.

I asked this question on Reddit's Rift subreddit and got a lot of really great responses.

I'll summarize here:

Minimums to be remotely effective (and to queue for randoms, thanks SirCobalt!):

• Normal Dungeons: 0 toughness/0 hit/0 focus
• Expert Dungeons 100 toughness/100 hit/100 focus
• T1 Raids (Drowned Halls, Gilded Prophecy, River of Souls, Greenscale Blight) 150 toughness/200 hit/200 focus
• T2 Raids (Hammerknell Fortress, Rise of the Phoenix) 200 toughness/300 hit/ 300 focus
• T3 Raid (Infernal Dawn) 250 toughness/400 hit/400 focus

For the raids, you really want 20 more hit/focus to ensure you never miss / get resisted. Akylios in T2 requires 360 hit/focus to never miss / get resisted.

To help the tank get to 100 toughness so we can start experts, he should get a Incandescent Indominatable Rune, +20 Toughness on chest. Transplanar + that rune is 84 Toughness, so you don't need anywhere close to a full Plaque gear set to reach toughness minimum.

Direct healers are unique in that they do not need focus/hit/toughness to succeed. They should just ensure they hit their stat cap (400 Wisdom for Clerics).
