Phantasy Star II — Cheat codes

Resurrect Nei

Even though Nei will be killed while fighting Neifirst, it is possible to bring her back to life while the three remaining characters are fighting. Before going to Climatrol have Shir steal some Moon Dew. Give it to one of the characters, except Nei. After Nei is killed, and during the fight with Neifirst, use the Moon Dew to bring her back to life.

Slow Motion

While traveling the countryside, pause the game by hitting START and holding Ⓑ>. While Ⓑ is held, you'll move around normally but in slow motion.

No Random Attacks

While moving, press Ⓒ to bring ⬆️ the control panel and Ⓑ to close it again. Better yet, if you have a turbo controller set the Ⓐ button to rapid-fire and hold it ⬇️ while walking.

Final Dungeon

In the final dungeon called Noah you can use Kain, the wreckers, magic against the enemies even though they are NOT mechanical. Normally Kain can NOT use his magic against biological creatures, but in Noah he can use all of his magic. This makes defeating the bosses Dark Force and Mother Brain much easier because Kain can use his magic NaGaj which does 150 damage. Therefore the best way to defeat Dark Force and Mother Brain is as follows:

Rolf: Megid followed by NeiSword when you run out of magic.
Rudo: NeiShot.
Kain: NaGaj followed by Lac Maces if you run out of magic (But you shouldn't run out, Kain usually has enough magic to last the whole battle).
Anna, Amy, or Hugh: Your choice. Have them use Star Mists to heal everyone. Plus they can attack if you do not need to be healed that turn.

Power Boosts

Every character has "power boost" levels, in which his or her stats (such as HP or Agility) raise dramatically (sometimes 20 or more!) To ensure the highest attributes for each character, save the game before a character raises to a "power boost" level. Because the numbers his/her attributes increase by are random, reset the game if you aren't happy with the new statistics.

Here is a list of the "power boost" levels for each character.

Rolf: every 4 levels

Nei: every 8 levels

Rudo: every 3 levels

Amy: every 6 levels

Hugh: every 6 levels

Anna: every 8 levels

Kain: every 7 levels

Shir: every 6 levels
