So Wyatt and his friend Melanie (belongs to another user on dA) had started hanging out and they've learned that their spells are both very different from one another, so they decided to spend some time learning about each other's tricks and what not.

Melanie showed Wyatt that she can use a charm to transform and disguise herself as others, where Wyatt can use his book to amplify the spells of other users (such as allowing Melanie to teleport farther or Annabelle to spread her paralysis with much more range). To do this the other user simply has to place their hand on a certain page of Wyatt's book and use their spell.

So how exactly can you amplify a spell that disguises you?
