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:
- be fed by a FOmar or FOnewm with a Viridia, Bluefull, Redria or Whitill section ID, and have its sum of DEF and DEX equal to its sum of POW and MIND, or
- be fed by a FOmar or FOnewm with a Greenill, Purplenum or Oran section ID, and have its sum of DEF and MIND equal to its sum of POW and DEX, or
- be fed by a FOmar or FOnewm with a Skyly, Pinkal or Yellowboze section ID, and have its sum of DEF and POW equal to its sum of DEX and MIND.
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.
