Ribhava リヴ is a third evolution MAG in Phantasy Star Online. A second or third tier MAG can become another third tier form when it is a level divisible by 5 and at least level 50 after feeding, but does not meet the requirements to evolve into any specific fourth tier form. To become a Ribhava, it must be fed by a force with an even section ID (Viridia, Skyly, Purplenum, Redria, Yellowboze) and have DEF lower than 45 and DEX higher than POW and POW higher than MIND. Only whole POW, DEX and MIND levels count for these comparisons; the 0%–100% progress meters are disregarded.
