[Japan] Orb conversion / Ability dismantling update

It appears that orb exchange and dismantling abilities is set to arrive with a new notice explaining some of the mechanics.

Dismantling Abilities
You will receive 50% of the orbs spent on the ability (including initial cost and subsequent upgrade costs) when you dismantle it

Orb Exchange
You can now upgrade the same types of orbs with a ratio of 10:1
10 minor for 1 lesser orb
10 lesser for 1 regular orb
10 regular for 1 greater orb
10 greater for 1 major orb

It looks like 4 and 5 star abilities are going to be much easily attainable with this!
