So this is for the half caster subclass in regards to how Enervating Spell works.

3rd-Level Architect of Ruin Feature
You gain the following two Invoke Hell options:
Enervating Spell. When you deal damage to a creature with an illrigger spell of 1st level or higher, you can expend a seal (no action required) and imbue the spell with weakening magic. The target has vulnerability to that spell’s damage. If they normally have resistance or immunity to the spell’s damage, that resistance or immunity is suppressed for this spell, and the target has vulnerability to the damage instead.

so I'm curious if I'm to understand "expend" a seal is "to consume a seal that you have available to place per short rest" or if the wording is meant to be synonymous with "burning" a seal, which is something you do AFTER you have placed the seal. It's a matter of understanding the order of operations.
Burning Seals. When an interdicted creature you can see within 30 feet of you takes damage from any source other than a seal burned by an illrigger, you can burn any number of seals you placed on them to deal 1d6 fire or necrotic damage (your choice) to that creature per seal burned. You deal this damage immediately after the triggering damage. Burning a seal doesn’t require an action from you, but you can’t do so while incapacitated.
Once a seal is burned, it immediately vanishes. Once you reach 5th level in this class, your connection to your archdevil strengthens. Each burned seal deals an extra 1d6 damage, for a total of 2d6. The damage of each seal increases again by 1d6 when you reach 11th level (for a total of 3d6) and 20th level (for a total of 4d6) in this class, as indicated in the Seal Damage column of the Illrigger table.

That's right. There's a section titled "Burn vs. Expend" that talks about it, but the important bit is "the illrigger expends an unplaced seal from their pool of available seals."

Ah, whoops! Musta missed it, thanks!
