Crafting stuff need clarification

Has lvl 2-3  crafting materials being released yet?

Are we able to get materials to craft lv2 and lv 3? Or are they yet to be released?
In particular I can't find moon gem for lvl 2 crafting

Are Crafted SPELLS based on to hit Stats?

Mana Leech - Assist or based on Curse Hit? 

Silence Spell - Assist or based on Curse Hit? 

Hamstring - Assist or based on Phy Hit? 

Foray - Assist or Phy Hit or Curse Hit?
