Another Noob thread: Eggs and rare items

[Oldsora]

Hello my friends, i have two questions this time.

What are the egg items?
And the items with a 50% in the description?

The eggs are for Summoner pets. The exp/stat eggs are purely for increasing pet stats and levling them, while the eggs of specific pets can also be used for things like changing pet personalities and increasing a pet's rarity.

Your second question isn't really specific enough. I assume you're talking about boosters, but I dunno which.

EDIT: Also use the quick question thread (http://www.pso-world.com/forums/showthread.php?t=213385) for stuff like this.

Eggs are Summoner Pets (except for the ones with a star on them, those are just food for the Pets); using one will give you the Pet that you then use as a Summoner.
Not sure which items you mean. Possibly Boosters? Screenshot might help.
Also, you can use the Quick Questions thread (http://www.pso-world.com/forums/showthread.php?t=213385&page=1917) for most questions like this.
