Sin of Pride

Unshakable vanity tricks your mind into seeing weakness in every opponent, fueling your triumph before the first strike.
Your arrogance distorts reality, convincing you that any creature far beneath your might poses no challenge, granting you effortless mastery over their every move. You gain the following benefits:

• Lionheart: if the user deems the foe “far weaker”, they may make a DC 15 Charisma (Intimidation) check. On a success, they gain advantage on their first attack roll or contested check against that creature. This effect can only be used once per short rest.
• Merciless: Whenever a creature within 30ft is recognized by the user as an "enemy" they come under the influence of Merciless. From that point on if they lose the will to fight (DC 5 Wisdom saving throw) or their heart is broken their soul comes under the influence of the user and allows them to reap it at any time (Instant Kill, No XP). Even if they were allowed to escape, their soul remains under the thrall of the user and can be taken at any time at the first thought of rebellion. (Lore/DM’s call)
