Zenithral pulls the jar out form his pack and unwraps it. Still in tact after their descent and fight, thankfully. Magically sturdy jar, perhaps? He scowls at the substance inside. Nym's deals usually helped them in the long run, whomever the patron, but at what cost?
"Will this quell the beast?" Zenithral thinks aloud. "Or incite it to destruction? Give the Spider Queen control of it, or simply lead it to hunt a different people in a future time?"
Intending to open the jar and empty it's contents, Zenithral closes his eyes and breaths a prayer, though he suspects the answer he'll get.
Zenithral expends a spell slot and takes a minute to cast Augury.
Weal, for good results
Woe, for bad results
Weal and woe, for both good and bad results
Nothing, for results that aren't especially good or bad
The spell doesn't take into account any possible circumstances that might change the outcome, such as the casting of additional spells or the loss or gain of a companion.
If you cast the spell two or more times before completing your next long rest, there is a cumulative 25 percent chance for each casting after the first that you get a random reading. The DM makes this roll in secret.
