Maplestory "High Five" Private Showcase

Spadow; A thought I just had earlier - Are the cores tradeable at all? If so, that is actually really good for a new market... something the game desperately needs.

Cores are not an item that go in your inventory. They appear directly in your V Matrix.

Does anyone know if you are allow to have more than one decent skill? or you have to replace or remove the old skill core?
If so how many Skill core can you place in your char? like i can have every single decent skill and job skill and level all those skill to max?

Decent skills are categorized as Skill Cores, so it means you can indeed have multiple equipped simultaneously. You cannot with Special Cores.
If you want, you can fill your Matrix with all Skill Cores.

I guess either I or Spadow misunderstood, then. He specifically gave the example of Blink as a skill with max level 1.
Do you get Core Gemstones for leveling up? Or does V included any other motivation to level up beyond 210, besides the Hyper Stats we already have?

Sorry, I didn't check thoroughly. Blink is a Skill Core so it has a maximum level of 50. Special Cores have a purple background in their icon. I corrected this in my explanation.
I don't know if you get Core Gemstones by leveling up, we'll have to wait till the update hits the public server. In the test server they are given for free with a daily limit.
