NO. It means they are immune to ANY SPELL OR SUPERNATURAL EFFECT THAT THEY ARE NOT SPECIFICALLY NOTED AS BEING VULNERABLE TO IN THEIR MONSTER ENTRY.
Words have meanings. And they mean what they mean. Not what you want them to mean. THe word you are missing is
most.
Just to expand on Billd91's point,
the official 3.5 FAQ can be found here. And is very clear and consistent in explaining that everyone else in this thread is right and you are wrong.
The entries for all the golems in the MM say that golems
have magic immunity, which is supposed to allow golems to
completely resist most magical and supernatural effects
except for specific ones listed in each golem’s description.
(Most of those heal, slow, or damage the golem.) Can you
cast beneficial spells on a golem? For example, can you turn
a golem invisible? Can you teleport one? Could you cast
darkness on a golem? How about fly or reverse gravity? To
put it another way, if you are not trying to directly cause
damage or drastically alter the golem (such as with
polymorph), will the spell work? Clearly, if you cast
darkness on yourself and the golem attacks you, once it
moves into the area of darkness, it can no longer see you.
But can you cast darkness on the golem? Could a golem use
a magic item, such as a ring of invisibility?
As noted in each golem’s entry, a golem resists any spell or
spell-like ability that allows spell resistance. (In previous
versions of the D&D game, golems were impervious to most
supernatural effects as well, but that is no longer the case.)
[Snip for length]
The golem description in the MM says that golems are
immune to magic, but the individual golem descriptions say
they’re only immune to spells or spell-like abilities that
allow spell resistance. Which one is right?
The “immunity to magic” entry in the opening text of the
golem entry (page 134 of the MM) is only a general description
of that special quality. Each golem’s specific immunity to
magic entry provides the actual rules mechanics for
adjudicating that immunity.
For example, a clay golem is immune to fireball (because
that spell allows spell resistance), but not to Melf’s acid arrow
(because it doesn’t allow spell resistance). It would be immune
to disintegrate, except for the special note that follows
indicating the effect of a disintegrate spell on a clay golem
Do conjuration spells such as Evard’s black tentacles
have an effect on golems?
The easiest way to find out if a golem is affected by a spell
is to check the spell to see if it allows spell resistance; if it does,
then the golem is immune to the spell. Many conjuration
spells—including Evard’s black tentacles—do not allow for
spell resistance, so they would work normally against a golem
Can a dragon’s breath weapon harm a golem?
Yes. Although the golem main entry describes “immunity
to magic” as granting immunity to “most magical and
supernatural effects,”individual golem entries clearly state that it applies only to “any spell or spell-like ability that allows spell resistance.” Thus, golems are affected normally by a dragon’s breath weapon unless the golem’s entry states otherwise.
Are golems immune to the warlock’s eldritch blast?
Since it is a spell-like ability that allows spell resistance,
golems are immune to the warlock’s eldritch blast. The
warlock who faces a clay golem with nothing but his eldritch
blast is in just as much trouble as the sorcerer with nothing but
magic missile and lightning bolt in his arsenal. The vitriolic
blast eldritch essence invocation (CAr, page 136) allows the
warlock to overcome this problem, since vitriolic blast ignores
spell resistance.
The FAQ is completely in line with the rules of 3.5. And is part of the official rules.
