Elemental Summoner

You’ve gained an affinity with elemental magic. Dealing a total of 25 hit points of consecutive damage to a creature summons a random stationary elemental orb to assist you for 30 seconds. The orb is summoned in an unoccupied space of your choice within 5ft which you can see. When an orb is summoned, roll a d6. When you or a friendly creature start their turn within 10ft of the orb, they gain benefits depending on the type of orb:

• 1: A green orb is summoned. Creatures within range heal by an amount equal to their Proficiency Bonus.
• 2: A blue orb is summoned. Creatures within range can add half their Proficiency, rounded down, to their Attack Rolls.
• 3: An orange orb is summoned. Any Attack Rolls made by creatures within range are a Critical Hit on a 19 or 20 on the d20.
• 4: A red orb is summoned. Creatures within range can add half their Proficiency, rounded down, to their Damage Rolls.
• 5: A purple orb is summoned. Creatures within range have advantage on Saving Throws.
• 6: A yellow orb is summoned. Creatures within range have advantage on Skill Checks.
