The enchanter's workshop has some spellsilver, six feet away from her, on a shelf.
Carissa tries to build a magical scaffold so she can tap this spellsilver six feet away and transform her Armillary Amulet into an Arrow of Slaying and use it to kill herself.
This requires a DC 40 Spellcraft check, which is only even possible to Carissa because her character is incredibly specialized on Spellcraft, weapons enchanting, and also she's just hit seventh level / 4th-circle as a wizard after her previous combat experience.
Lintamande rolls for her. She makes it.
Somebody is very impressed by this:
Now that's just bullshit. Seventh-circle wizard, yes. Perhaps a prodigal and specialized fifth-circle wizard. Third-circle who maybe just hit fourth, no.
Skeptical sane people would not believe this Carissa Sevar fact.
All right, keep going then. Are you actually going to pull this off.
After Carissa has been allowed to try in apparent privacy for 15 minutes - long enough for it to be clear that she could succeed - Abrogail Thrune appears.
"That is the most impressive feat I have seen anybody even try from that position."
