Branch of Knowledge

You raise up the twig, which quickly grows into a large wooden axe. Make a melee spell attack against any target within 15 ft. On a hit, deal 4d6 slashing damage, which is considered magical for the purpose of overcoming resistances. For the next 1d4 rounds, gain a +2 to your damage rolls and a +1 to your AC. However, you also receive -2 to all attack rolls, skill checks, and saving throws until the buffs expire. If you miss the attack, deal half-damage, and instead of the previously listed buffs, gain +2 to your AC and a +2 to all attack rolls, skill checks, and saving throws.
