What to do with a dead will-o-wisp?

At the end of the last session, the party recovered the remains to the defeated and dead Will-O-Wisp.  Black and furry.  About the size of volleyball.  Limp and lifeless, with stubby tentacles spread over it in an asymmetrical pattern. 

The players asked at the time what the value of this corpse might be, and I wasn't prepared with a good answer.  But I think I have an answer now that fits into the mechanics of the game.

The oils of the Will-O-Wisp make fine material components.  The possess the properties of rare herbs (used in Nature-based rituals), alchemical reagents (usef for arcane rituals), and mystic salves (used for healing rituals).  (See page 300 of the PHB for a discussion of material components for ritual magic).

The value of this is 300 GP in material components, used for Arcane, Nature, or Heal rituals. 

Session #29 - Will-o-wisp/spriggans part 2

Making good on their offer to help Phiglia the dryad rid her forest of the Will-o-wisp, the party set an ambush. They used good tactics to attack the will-o-wisp directly. They also spent a ton of resources (daily popwers, action points) to knock it out quickly. The divded group of spriggans was defeated fairly quickly after that.

In the two combats combined, the party faced:
will-o-wisp (L10 lurker, 500) X 2
Spriggan thorn (L6 soldier, 250) X 3
Spriggan Powrie (L7 Skirmisher, 300) X 3
Spriggan Withereer (L8 artillary,350) X 1
Spriggan Giantsoul (L8 brute, 350) X 1

I'm dividing these points over 5 character for both combats. Although Brian was absest the second session, the Dryad fought as an ally of the party.

I'm also awarding 1000 pts to the party for completing a level 5 quest, in successfully completing the mission that the Dryad asked them to do.

  By my count, each character now has 8480 XP. You need 10000 for L7.

Treasure awarded in the last 2 sessions:
Ebony Fly magic item
1150 GP
500 GP gem
250 GP worth of "art objects"
(Art objects: 2 bolts of fine silk (50 gp each), a ceremonial helmet, fashioned from silver to represent a dragon’s head with two tiger eye gems set into the eyes and stylized fangs made from inlaid ivory (75 gp), and a pendant, fashioned from gold filigree and set with an apple-green, translucent Chrysoprase gem (75 gp).)

Perra used his intimidate ability to get one of the surviving spriggans to pay the party a ransom of treasure in exchange for his release.

Session #28 - Will-O-Wisp

The party crossed through the stone ring portal, using a magic word to activate teleportation that Gevin found carved into one of the stones. On the other side, they found themselves within another stone ring, but clearly in a different place. The woods were much denser here, and the stone ring was mo0re worn, and appeared to be very ancient. The party camped there to heal their wounds from the spider valley. During the night, Yosh was drawn towards a mysterious light in the forest. This turned out to be an ambush by a will-o-wisp and 4 spriggans. The party killed 3 of the spriggans, and captured the 4th, but the will-o-wisp escaped. I'll hold off on awarding experience for this encounter until we continue next. A dryad living in the forest presented herself to the party. She explained to them that this will-o-wisp had been haunting her forest for quite some time, and it often allies itself with small bands of spriggan bandits. She promised the party that she would aid them in their quest to find The Arbiter if they would help her remove the will-o-wisp from her woods. She presented the party with an Ebony Fly magic figurine to help chasing the will-o-wisp. To be continued...
