Blood God's Engorgement

You cause a creature you can see within range to grow larger for the duration. If the target is unwilling, it can make a Constitution saving throw. On a success, the spell has no effect.

Everything it is wearing and carrying changes size with it. Any item dropped by an affected creature returns to normal size at once.

The target's size doubles in all dimensions, and its weight is multiplied by eight. This growth increases its size by one category-- from Medium to Large, for example. Until the spell ends, the target also has advantage on Strength checks and Strength saving throws. The target's weapons also grow to match its new size. While these weapons are enlarged, the target's attacks with them deal 1d4 extra damage.
