As in Xanathar's Guide to Everything except the upcasting option has been altered as follows:
At Higher Levels. When you cast this spell using a spell slot of 5th-level or higher, the challenge rating of the creatures summoned increases by 1 step for every two slot levels above 3rd. For example, the spell summons one creature of challenge rating 3 or lower, two creatures of challenge rating 2 or lower, four creatures of challenge rating 1 or lower, or eight creatures of challenge rating 1/2 or lower when cast at 5th level.
