Does War God's Blessing affect Bigby's Hand's attacks?
The description states that a creature can benefit from it, but the hand is an object. PHB pg.63:
When a creature within 30 feet of you makes an attack roll, you can use your reaction to grant that creature a +10 bonus to the roll, using your Channel Divinity.
On the other hand, the description for Bigby's Hand attack states that the attack roll is made using the caster's stats, not the hand's, so one could argue it's an attack made by the wizard, therefore justifying the Blessing. PHB 218:
The hand strikes one creature or object within 5 feet of it. Make a melee spell attack for the hand using your game statistics.
What's the correct interpretation for the blessing in this situation?
