I have no idea how in the heck this would translate to the DL, but it's easily verifiable in-game: Blazeghosts are immune to Blaze but not immune to Firebal or Bang.
This only really matters for Mara in any case, and even then I'm not sure it makes a lot of difference, but it's interesting. Djinn thought it might have been documented on the old boards but not survived to the new ones. In any case, here~
EDIT: On reflection it matters for bosses too. I'm only looking up the major bosses right now, since it's kind of a pain in the butt finding them in Japanese. Anyway: so, there's 6 damage elements recognized by DQ4 - Bang, Firebal, Blaze, Zap, Infernos, and IceBolt. They cover the following spells:
Bang - Bang, Boom, Explodet
Firebal - Firebal, Firebane, Firevolt
Blaze - Blaze, Blazemore, Blazemost
Zap - Zap, Thordain
Infernos - Infernos, Infermore, Infermost
IceBolt - IceBolt, Snowstorm, IceSpears, Blizzard
There's also resistance flags for each of the following spells: Surround; Sleep (also covers Sleepmore, albeit in a special way to be discussed below); Beat (also covers Defeat); Expel; RobMagic; StopSpell; Chaos; and Sap (also covers Defence).
Monsters can have one of 4 "affinity levels" to each spell type, which affects how likely a spell of that type is to fail and have no effect on them. DQ4 resistances are all or nothing; there is no damage reduction, spells either do full damage or miss entirely. Affinity levels work as follows:
Level 1 - 100% chance of success
Level 2 - 75% chance of success
Level 3 - 25% chance of success
Level 4 - 0% chance of success
There is one exception to the above success rates, and that exception is Sleepmore. Sleepmore rolls for success rate twice, and will hit if *either* check hits. Also, it's already noted in the topic, but I'll restate it here: the random Sleep proc on the Sword of Lethargy
does not check Sleep resistance at all, and works on everything in the game.
So, here's the Chapter 5 boss affinities. Note that I can only guarantee these are accurate for DQ4 NES.
Anderoug: Bang 4, Firebal 3, Blaze 2, Zap 1, Infernos 1, IceBolt 1, Surround 2, Sleep 3, Beat 3, Expel 4, RobMagic 4, StopSpell 4, Chaos 3, Sap 1
Balzack: Bang 1, Firebal 1, Blaze 1, Zap 1, Infernos 1, IceBolt 4, Surround 4, Sleep 4, Beat 4, Expel 4, RobMagic 4, StopSpell 4, Chaos 4, Sap 4
Esturk: Bang 3, Firebal 3, Blaze 2, Zap 1, Infernos 4, IceBolt 2, Surround 4, Sleep 3, Beat 4, Expel 4, RobMagic 4, StopSpell 4, Chaos 4, Sap 3
(Note that while Esturk is vulnerable to Sleep, he can still make basic physical attacks while asleep as a special enemy property. Since those tend to be his most damaging move, putting him to sleep can actually be dangerous.)
Gigademon: Bang 1, Firebal 1, Blaze 1, Zap 1, Infernos 1, IceBolt 1, Surround 4, Sleep 4, Beat 4, Expel 4, RobMagic 4, StopSpell 4, Chaos 4, Sap 1
Infurnus Shadow: Bang 3, Firebal 3, Blaze 3, Zap 1, Infernos 1, IceBolt 2, Surround 4, Sleep 4, Beat 4, Expel 4, RobMagic 4, StopSpell 3, Chaos 4, Sap 2
Keeleon: Bang 2, Firebal 1, Blaze 2, Zap 1, Infernos 1, IceBolt 2, Surround 3, Sleep 4, Beat 4, Expel 4, RobMagic 4, StopSpell 3, Chaos 4, Sap 1
Necrosaro: The final boss actually has different affinities across its phases as follows.
