Legendary, Requires Attunement
This great sword of power does 2d6 slashing damage on a strike. When attuned, the wielder can use an Action to raise the sword over their heads and say the command words “I have the power!”
Once activated with the command word, the wielder grows larger and stronger. Their strength becomes 21, the wielder also has advantage on Strength Checks and Strength saving throws. The weapon’s damage increases by 2d6 and all damage becomes Radiant damage.
Every friendly creature within 20ft when the command words are spoken, including the wielder, are immune to the Fear condition. As a Bonus Action, when the command words are spoken and if the character is a Beast Master Ranger, they can also cast Enlarge on their pet. The pet gains advantage on all Fear or Charm Saving Throws and becomes one size larger. The pet’s attacks also do an additional 1d4 radiant damage. If the player is not a Ranger, they can instead cast Summon Steed twice per long rest.
After the command words are spoken, both the wielder and their pet gain a +1 to AC as matching magic armor appears over parts of their body to match their new, larger form. All the characters worn items change in size, as do all weapons, wands, armor, etc.
