I forgot to list my spells I have prepared for the day.

Level 0:
No Light
Slash Tongue
Guidance (This spell s so underrated, +1 for basically anything and can be held for 1 minute)

Level 1:
Seething Eyebane
Spider Hand
Cause Fear

Also, can other people make a perception check on the warden to see what he is doing?

edit: and is TN just another name for DC?
