  1. See "A Tangled Web" (2x77) from 2:02:11 through 2:04:54.  Essek teaches Caleb two more dunamancy spells, Resonant Echo and Immovable Object. Level initially inferred from the 300 gp total cost of paper and ink to transcribe the two new spells. Since Immovable Object has now been confirmed as 2nd-level, Resonant Echo must be 4th.
  2. 2.0 2.1 See Matt Mercer's tweet explaining that the spell was unique to Essek, and had to be omitted from the Explorer's Guide to Wildemount for space reasons.
  3. See "Xhorhas" (2x51) from 1:54:59 through 1:56:31.
  4. See "A Tangled Web" (2x77) at 2:02:56.

  6. See "With Great Power..." (2x94) from 0:40:22 through 0:50:11.  Caleb's echo took 13 points of bludgeoning damage and was still up, and able to cast Fireball on its turn.
