Time Dilation Boon - From Emerald Spire - The Tomb of Yarrix (11)

[WaterDragon]

I maybe a bit thick. I have a hard time understanding the book Time Dilation.

Spoiler:

Boon
"You can use this boon when casting a non-instantaneous spell that affect an area to apply the Linger Spell metamagic feat to the spell without increasing the spell's level."

Lingering Spell
"Benefit: You may cause an instantaneous spell that affects an area to persist until the beginning of your next turn. Those already in the area suffer no additional harm, but other creatures or objects entering the area are subject to its effects. A lingering spell with a visual manifestation obscures vision, providing concealment (20% miss chance) beyond 5 feet and total concealment (50% miss chance) beyond 20 feet."

Since you cannot use it for instantaneous spell, so how do you use this boon?

First off, spoiler tags, yo!

Second, there's another half to the boon with an alternate usage. It's reasonable to assume that the first half (which you quoted) is just an editing error. IIRC, these sheets were slung together pretty quickly.

Thanks. I should of.
I guess the first half is just an error then?
