If I have one memorized, please assume Umbriel casts Nerveskitter (+5 init for all PCs) whenever the party rolls initiative.
For the GM:
Spoiler
Umbriel takes 10 on her CL check (using her Arcane Mastery feat) to get 29. Succeed or fail, she'll learn something interesting
Also, can you confirm my Contingency is okay? I basically want a Silence to go off (targeted on Umbriel) if the party is about to get hit with a Blasphemy/Holy Word/Word of Chaos/Dictum, or Wail of the Banshee. If possible, I'd also like to use my Extraordinary Spell Aim feat to exclude Umbriel from the effect of the spell, at the time that I cast it into the Contingency.
