Pain of Solitude

The Pain of Solitude (ソリチュードペイン) is a form of Roxas's Kingdom Key which appears in Kingdom Hearts 358/2 Days. It can be upgraded to the Pain of Solitude+. It is one of Roxas's most basic Keyblades, and therefore only provides one ability; further proof is that it has to be upgraded to access this ability. The Pain of Soliitude is a basic magic-oriented Keyblade, as it provides a strong boost in Roxas's/Xion's magic strength, and the Pain of Solitude+ can provide an ability that increases the strength of Fire magic.

The Pain of Solitude and Pain of Solitude+ have the same construction as the Missing Ache.
