Blessing of the Gem Dragons

The seven crystal dragons — guardians of Dream, Time, Space, Entropy, Growth, Identity, and Destruction — have bestowed their blessing upon you. Your echo shimmers in slowly rotating colors: milky white, emerald green, sapphire blue, topaz orange, lavender violet, opalescent silver, and prismatic white. Their domains flow through it.

When you finish a short or long rest, choose one of the seven domains below. Your echo takes on that domain's color and gains the associated benefit until you finish your next short or long rest.

Dream (Druseldiax — milky white)
While your echo is manifested, it flickers at the edge of perception like a half-remembered dream. Creatures have disadvantage on opportunity attacks against your echo. Additionally, when your echo is within 5 ft. of a sleeping creature, you can see that creature's dreams (no action required, lasts up to 1 minute).

Time (Veranixia — emerald green)
If your echo is manifested when you roll initiative, you and each ally within 10 ft. of the echo add 1d4 to their initiative roll.

Space (Placien — sapphire blue)
Your echo can be manifested up to 60 ft. away from you (instead of 15 ft.) and can move up to 60 ft. when you use your bonus action to move it. The echo can also see around corners and through thin barriers — while it is manifested, you can see through its eyes as a bonus action until the start of your next turn.

Destruction (Ammariaxus — ruby red)
Your echo crackles with chaotic energy. When you make a melee attack through your echo, the attack deals an extra 1d4 force damage to the target and each enemy within 5 ft. of the echo.

Growth (Idanex — lavender violet)
Your echo pulses with restorative energy. When you make a melee attack through your echo and hit, you or one ally within 5 ft. of the echo regains 1d4 hit points. Alternatively, you can use your echo's attack to heal instead of attacking: as an action, one ally within 5 ft. of the echo regains 2d4 + your Constitution modifier hit points. This healing action can be used once per short rest.

Identity (Adula — amber orange)
Your echo does not look like you — it takes the appearance of the ally nearest to you when you manifest it (including their gear and mannerisms). Enemies cannot distinguish the echo from the real person without succeeding on an Investigation check (DC 8 + your proficiency bonus + your Constitution modifier). You have advantage on Deception checks while the echo is manifested.

Authority (Ezikes — topaz yellow)
Your echo radiates command. While your echo is manifested, allies within 10 ft. of the echo (not you — the echo) can add 1d4 to saving throws they make. This benefit applies to a maximum of 3 allies and does not require your concentration.
