Bannerman's Boon

You plant a flag or banner onto the ground to inspire your allies. For the duration of the spell, the symbol cannot be moved or damaged, and it emits a 60-foot aura of power. Friendly creatures that start their turn within the area gain one of the following benefits of their choice at the start of each turn:

• Invigorate. Your walking speed increases by 20 feet until the start of your next turn.
• Empower. You have advantage on the first attack roll you make before the start of your next turn.
• Ward. You gain a +2 bonus to your AC and all saving throws until the start of your next turn.

During each of your turns while concentrating on this spell, you must use your bonus action to maintain the spell's effects, and the spell ends if you fail to maintain it.
When the spell ends, friendly creatures in the aura regain 1d6 hit points.
