Spell Forgery

Your skill at writing in various styles and inscribing spells has given you the following benefits:

• Increase your Intelligence or Charisma score by 1, to a maximum of 20.
• You gain proficiency with Deception and Forgery Kit. 
• You can use a forgery kit while scribing spell scrolls and spellbooks to make it appear as though they were scribed by someone else.
• You can create fake spell scrolls. These fake scrolls appear to be real magical spell scrolls to a casual observer. Even a trained magic user would not easily be able to tell that they are fake. This does not affect how they appear to a spell like detect magic or identify. However, if a spell such as arcanist's magic aura were to give it a false aura, it could be nearly undetectable as a fake. 

If a creature attempts to cast a fake spell scroll, the scroll remains and nothing happens. However, attempting to cast from a fake spell scroll does cost an action, bonus action or reaction based on the spell being faked.

Example: A creature tries to use a fake scroll of misty step, a spell which only uses a bonus action to cast. Being fooled by the fake misty step scroll would only consume a bonus action, not a full action.
