I am currently using this setup on my lvl 45 sorcerer: crit behind, crit boss behind, crit enraged, crit %

I can crit about 60-80k on bosses with this setup. But i am wondering, later when I get the celerity buff, will this crit build still do the most dps OR would stacking 4 boss damage% OR 4 mp regen be better with that insane aspd boost?

I'm actually a sorcerer and even with 4 mp regen crystals i still run out of mana.

I tried the crit mp regen but it doesn't seem to happen on every critical hit and the amount it generates is also pretty low.

Does max mp crystal help with base restoration at all? Because im finding that the mp regen crystal isn't fast enough in battle.

Is it just me or tera doesn't specify anywhere what types of monsters go in which category?

I know there are minions, small monsters, normal monster, large monsters, and boss monsters.

What is a bam considered (like a basilisk)? large? or boss? If so does boss only refer to world boss?

This is all very confusing and i would love for some clarification because I want to know which crystals actually work against which monsters.
