Phantasy Star IV Rune Lutz Walsh Skills
Rune Walsh joins early on, showing up at the destroyed village of Molcum. Alys quickly recognizes him and seems in awe of his presence, though how the two know each other is not detailed. Shortly after joining you, Rune's power is obvious. He has dangerous magic skills no one in your party has seen, and Hahn's techniques pale in comparison to Rune.
Rune leaves the party early on, but comes back later after the 'Alys event'. He stays in your party for good, and you learn a bit more about this mysterious wizard's past. Hard to believe the sixth generation Lutz is this arrogant, but this is confirmed at the Esper Mansion on Planet Dezolis. Chaz's quest becomes more clear at this point, with the wizard Rune at your side. Rune is arguably the most valuable member of your party (not to say that Rika / Chaz / Raja are slouches though).
Like Hahn Mahlay, Rune is best-equipped with two shields. His cane is so weak not to mention it requires two hand slots. Just not worth the defensive drawback. Giving him two shields early on makes him an absolute terror to penetrate with his already impregnable magic defense. Rune has a ton of technique points at his disposal, and plenty of skills to use. He gets the absolute best techniques and probably skills too. No healing skills, but they can't make him perfect. He even has Hinas and Ryuka to exit out of caves / teleport around the world.
Note that Rune is already at level 17 when he joins.
