Banner of the TwiKnight Moon

By declaring your vow and steeling your resolve, an 'Echo' of you appears and hovers within your space for the duration, carrying the Divine Banner of the TwiKnight Order of the Blue Moon. The Banner's light washes out in a 30-foot radius around you in a soft starry radiance, coalescing echoes of you to aid your allies. Whenever creatures of your choice (including you) end their turn within this radius, they can apply a bonus of half the caster's Spellcasting Modifier (with a minimum bonus of +1; rounded down) to one of three benefits (benefits do not stack):

- Whenever you must make a saving throw, you add the bonus to the saving throw.

- When you end your turn within 5ft. of a hostile creature, you can add the bonus to either your Armor Class or Attack Rolls.

- Pick one ability score (STR, DEX, CON, WIS, INT, CHA). Whenever you make an ability check with the chosen ability, you can add the bonus.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the spell's range increases by 10ft for each slot level above 5th.
