Spell Thief

You have gained the ability to steal spells from another spell caster.

Using a reaction, you may steal the spell of another mage within 100 feet of you as long as you can hear and see the mage casting the spell. You can only steal one spell at a time and can only steal a spell that is cast at a spell level you can cast. You may cast the spell without using material components and can only use this ability equal to you proficiency bonus every long rest. Spells are still stolen if you take a long rest but they count against how many times you can use the ability the next day.

When you become level 14, you can steal a spell higher than your known spells using twice the requirements.

Magic Strike

You may use a magic cantrip in unison with "sneak attack" an equal amount to your proficiency bonus. You nust announce the attack before you hear the result.

Critical Spell

You may use a magic cantrip in unison with "sneak attack" an equal amount to your proficiency bonus. You nust announce the attack before you hear the result.

Rapid Spell Steal

If you are holding a stolen spell, you may use your reaction to hastily throw out a stolen spell and steal another one.

If you do this, the thrown spell has disadvantage to hit if it is a ranged spell and enemies have advantage on saving throws against it.

You do not suffer any of the negative consequences if you are "sped up" from an outside source such as a haste spell

The Ol' Switcharoo

Using a reaction, you have the ability to switch places with any creature or abject within 100 feet of you that you can see. This does not work on creatures or objects that are not normally able to be moved or are magically tethered into place.

You can use this ability a number of times equal to your proficiency bonus.
