Game Mechanics: Pet immunities

[Metallikus]

59 necro spectre pet is supposed to be immune to fear

mage fire pets are supposed to be immune to fire

mage water pets are supposed to be immune to poison

Is there something coded different on this server where pets take on the resists of the owner instead of checking immunities?

edit: they do use master resistances at some point: http://www.tski.co.jp/baldio/patch/20020724.html "Pet Resistance Changes: Pets will now use their master's level and resistances when saving against spells cast by NPCs (against PCs pets will use their own resistances and level as they always have) - unless the pet has special resistances, in which case it will use that resistance."
