Spellcaster's Apprentice

You must have at least witnessed your trainer's abilities at using magic.  Why can't you cast that spell as well?

Minor Prerequisites:

• Must be a Spellcaster
• Must have a Spellbook or scroll
• Must be able to read spell
• Must have components needed
• The Spell has to be within the class you are currently using

If you have all the Minor Prerequisites, you can attempt to cast an advanced spell beyond your abilities.  There is a chance your spell will fail.  It will push you beyond your abilities and cause exhaustion.  You can only use this feat once per long rest so choose wisely.  You can use this feat to enhance your regular spells (that have the ability to) casting them at higher levels.
