Vema Elf
Quick Thoughts. You have proficiency in the Investigation skill.
Blessings of the West. You know the Minor Illusion cantrip. Intelligence is your spellcasting ability for it.
Western Mirage. When you take the Dash action, you can leave behind a still image of yourself. A creature must succeed on a DC10 Wisdom saving throw before approaching you, or mistake the still image for you. On a successful save, the creature is immune to being tricked by the still image for 24 hours. You can use this feature a number of times equal to your proficiency bonus before completing a long rest.
