The description of the hollyphant's Aura of Invulnerability trait says:

An invisible aura forms a 10-foot-radius sphere around the hollyphant for as long as it lives. Any spell of 5th level or lower cast from outside the barrier can't affect creatures or objects within it, even if the spell is cast using a higher level spell slot. Such a spell can target creatures and objects within the barrier, but the spell has no effect on them. Similarly, the area within the barrier is excluded from the areas affected by such spells. The hollyphant can use an action to suppress this trait until its concentration ends (as if concentrating on a spell).

The description of the Sequester spell says, in part:

If the target is a creature, it falls into a state of suspended animation. Time ceases to flow for it, and it doesn't grow older.

The description of the Imprisonment spell's Minimus Containment option says:

The target shrinks to a height of 1 inch and is imprisoned inside a gemstone or similar object. Light can pass through the gemstone normally (allowing the target to see out and other creatures to see in), but nothing else can pass through, even by means of teleportation or planar travel. The gemstone can't be cut or broken while the spell remains in effect.

Basically I want a hollyphant in a gem necklace, so I can be immune to spells of 5th level and lower.

Does this RAW/RAI legally work?

    \$\begingroup\$ (I'm not really sure how the sequester spell is even relevant to what you want to do, other than keeping the hollyphant from dying of old age? I don't know how long they live, or whether they age in the first place. Or is the goal of sequester to prevent the hollyphant from using an action to suppress the Aura of Invulnerability trait?) \$\endgroup\$ – V2Blast Jul 20 at 5:59

The aura will not be projected out of the gem, because Imprisonment spell text quite explicitly says

nothing else can pass through

This is a rule specific to being imprisoned in this particular way, so it takes precedence over hollyphant generally projecting its aura while alive. Here is a rules link and here is a QA about this rule.

This QA discusses if auras should penetrate total cover in general, but again the spells explicit feature will override any more general rule, or lack of a rule, about this.

Also, if a DM wishes to rule otherwise, they should consider this: If it could, there are a bunch of other auras, not to mention gaze effects and other similar things, which might "leak" too, depending on exact wording of the feature. That would quickly make things rather silly.

  • \$\begingroup\$ Just to nitpick a bit... but gazes would require you to see the face of the creature and not all imprisonments allow you to see the creature so you might change "would" to "could"... \$\endgroup\$ – Slagmoth Jul 20 at 15:48
