The Aegis Shield provides an extra 33% chance to avoid a wide variety of magic attacks, including many that otherwise always hit. This doesn't work if the user has 'stop', 'paralysis', 'confusion', or 'sleep' status, or is both the attacker and the target.

Thanks to freestorageaccount for reminding me of the stat bonuses, which I'd somehow missed.

The Elf's Manteau provides an extra 33% chance to avoid most physical attacks. This doesn't work if the user has 'stop', 'paralysis', 'confusion', or 'sleep' status, or is both the attacker and the target.

Note that death when the 'death sentence' timer expires ignores instant death immunity, so equipping a Ribbon or Bonemail won't help.

The high defense and status immunities can be very helpful, but being Undead is highly risky. Healing becomes a real problem, since most curative effects will cause damage instead. Even worse, if the character goes down, there's no way of recovering before the battle ends—reviving items and abilities simply don't work. On the plus side, Death, Level 5 Death, and some other instant death abilities fully heal the character (if not already 'incapacitated'), and draining abilities will heal the user instead of causing damage. Don't think that means absolute safety from instant death, though, since some abilities (like Dejon and death from Countdown) ignore both 'incapacitated' immunity and being Undead.

Note that all effects of being Undead only apply during combat. You can heal as usual in the field without changing equipment.

Abilities that can heal Undead include White Wind and the Sylph summon. Wearing a Protect Ring also provides periodic healing despite the 'regenerate' immunity. Poison attacks work, too, but if you want to use Bio, be warned that 'slip' still takes effect and causes ongoing damage after the initial hit.

Gives a +50 bonus to A (effective attack power) with the Monk's Martial Arts skill when attacking unarmed or using !Kick.

The Ensanguined Shield appears to be unused. Its high defense with drawbacks fits well thematically with the Bonemail, Crown of Thorns, and Ring of Curses. Perhaps a virtual lack of any evasion didn't seem like a serious enough downside.
