Inspiring Leadership. As an action you can speak a magic word of inspiration to one creature you can see within 30 feet of you.

Wyrmslayer. As an action, you can point the blade at a dragon within 30 feet of you. The dragon must then succeed on a DC 17 Constitution saving throw or gain vulnerability to all damage types until the end of your next turn.  For the purpose of this weapon, "dragon" refers to any creature with the dragon type, including dragon turtles and wyverns. This property can be used three times. The blade regains all expended uses at the next dawn. Additionally, when you hit a dragon with this weapon, they take an extra 3d6 damage.

Wyrmrune Shield. You have immunity to the damage caused by any dragon's breath weapon, you lose this benefit if your turn ends and you haven't hit a dragon since your last turn.

Aspect of Heartkiller. In addition, you can use an action to take on the aspect of Heartkiller. When you do, you spark with the power of giants and your eyes glow bright white. The aspect lasts for 1 minute or until you end it early using a bonus action. While the aspect persists cloud-like wings form on your back, you gain a flying speed of 30 feet and can hover. For the duration, you also gain the following benefits:

• Giant's Skin. You gain immunity to cold damage.
• When you take damage from an attack, you can use your reaction to give yourself resistance to all of that attack's damage on this turn (you only resist that one instance of damage, e.g., if the same creature attacked you again you would not resist that second attack). 
• When you hit a creature, you can expend a spellslot (of second level or higher) to create a ball of freezing ice, the ball last of a number of rounds equal to half the level of the spellslot, choose a point within 30ft you, a ball of pure freezing ice is created at that point. At the end of your turn, each creature within 15ft of the ball must succeed on a DC 17 Constitution saving throw or take 2d8 x the level of the spell, cold damage and have its speed halved until the end of your next turn. Once this feature has been used it cannot be used until you take up the aspects of heartkiller.

Personality. The sword's purpose is to bring ruin to the dragons. Killing their worshipers, destroying the dragons hoards, and aiding the giants all help to fulfill this goal. The sword's obsession with it goal eventually becomes a fixation for its wielder.

Destroying the Blade. As long as the giant kingdom exists, the blade cannot be destroyed. However, if a dragon were to attune to this weapon, in a humanoid form, it would temporarily vanish from existence for 1d100 years.
