Nidra ニドラー is a fourth evolution MAG in Phantasy Star Online. Fourth evolution MAGs are only available in Episode I & II and later versions of the game, and are displayed as rare items. A second or third tier MAG can become a fourth tier form when it is a level divisible by 10 and at least level 100 after feeding. To become a Nidra, it must: Only whole DEF, POW, DEX and MIND levels count for these equations; the 0%–100% progress meters are disregarded. Fourth evolution MAGs, including Nidra, will not evolve further.
