Own Experience of (contemporary unrevamed zones on) Live:
lvl 50 gate guards: uncharmable (qeynos, oggok, neriak)
sub 50 city guards: uncharmable (qeynos, oggok, neriak - this includes the exhausted guards and sewer sentinels in the qeynos aqueducts)
neriak cleric guild guards: uncharmable
neriak 3rd gate city guards: uncharmable (these seem to all be SKs!)

Hi i have a lvl 30 enchanter and i decided to charm solo guards. Unforunately i found out that guards cannot be charmed (fortunatley i had rune up and tried to charm the guards near the zone). I was wondering if i could charm anything else in the zone for killing or i should use my uncontrollable pet? Also can guards be mezzed i see no reason why the shouldnt but just wondering.

Guard Fefslan "Immune to charm." note: (this guard appears to have been added/adjusted post classic to be part of the newbie armour/weapons quests).

So I handed in about 340 times and got from dub to amiably. Then he started to walk away, as I was not finished I try to charm but stupid guards cant be charmed so not sure where he was heading too...

One poster asks whether Lucan's guards can be charmed/mezed/etc and a subsequent poster advises (in era) to entrance them.

A more contemporary poster advises in 2021 Lucan's guards are uncharmable and reiterates the advice to mez and burn.
Legacy of Ykeshka onward Neriak C Gribnor's guards (these are body guards - not a city guard)

Gribnor's 'guards' (Ykesha era - in Neriak) are charmable (but these are body guards and not city guards).

Get a shaman and an enchanter with best cha possible sow both shaman heals enc charms... This dumb guard hits for 90ish and bashes for 32 charm him sic him on drakes and have fun
[You must be logged in to view images. Log in or Register.] has low hp though so have shaman heal it while its enc pet. if shaman is level 19 malise it so charm sticks better and if charm breaks run like the wind, root, and recharm this is a power levelers dream...
Summary: City Guards appear to have been uncharmable since at least 2000. This includes low level guards, but it does not include all village/wilderness NPC's with 'guard' in their name that also don't use guard model/skins/factions (as found in East Karana, Lake Rathe, Mountains of Rathe, etc).
