Can I clear this up?

FireHorn Bird - Dragonclaw Ring
Sea Creature - Dragonclaw Crystal
Centaur Knight - Lightning Sword
Killer Siafu & Serpent Master - Fruit from the tree of life

I'm reaaaaally confused ABOUT these drops....
Are these things PREMIUM only DROPS?

Because it took me 2 weeks already that I didn't even got one item on my character....
I'm a non-premium so.... What's THIS??!
