Juggernaut's Pauldrons and non-humanoids

[Guru-Meditation]

Can Juggernaut's Pauldrons be used by a non-humanoid to get to Large size?

While the Enlarge Person spell itself only targets humanoids i read somewhere that i cant find again that if items refernce spells for their effects, they do not concurrently apply the restrictions a refernced spell may have. Just that their effects are what the spell would generate.

Like if an item would refernce the "Sleep" spell in how it works, this would not also mean that it caps at affecting creatures with 4 HD. Or like in this question here, referencing "Enlarge Person" is only for what effects happen, but not that it also imports the "humanoid creature" as a restriction.

So, how does this work?

Pauldrons, Juggernaut’s

Aura faint necromancy; CL 5th
Slot shoulders; Price 40,000 gp; Weight 1 lb.

These massive pauldrons take the shape of a pair of clenched fists made of beaten bronze. They bestow a +4 bonus on CMD, and grant the wearer the ferocity ability. On command, the wearer can increase its size, as though subject to an enlarge person spell, and can revert to regular size with another command. Three times per day, as an immediate action after the pauldrons’ wearer kills an opponent, the wearer gains the benefit of the deadly juggernaut spell for 1 minute.

I believe you are thinking of the fact that magic items do not typically behave like the spells used in their construction. Effects that say "as if using (spell)" function exactly like (spell) unless otherwise noted, including such restrictions. So I'd have to say no go for non-humanoids. Interested to hear if there are other opinions for this particular case though.

It says, "On command, the wearer can increase its size, as though subject to an enlarge person spell..." The first part, 'the wearer can increase its size' is an independent clause while 'as though subject to an enlarge person spell' is a subordinate clause. The ability of the pauldrons is to increase the wearer's size; that's it. The subordinate reference to Enlarge Person is to point where you can retrieve the rules elements for what happens when your size increases, but the increase of size is a foregone conclusion. A non-humanoid is not a valid target for the Enlarge Person spell, but that doesn't mean that its effects/rules elements cannot be applied if not using magic spell targeting rules. Now, if it said you can cast Enlarge Person on yourself as a spell-like ability, that'd be different. But the way it's written, the enlargement doesn't rely on the targetability of the Enlarge Person spell.

I concede Kazaan's point.
