Obviously, the investment depends on your combo (starting points). At first level of mastery, level 9 spell summons but 1 elemental. At fourth level of mastery, level 9 spell summons 2 elementals. So the answer is 39 I guess. Since v1.03.21, as per changelog, any high level summoning spell summons +1 unit every other level of mastery (1, 3, 5) or +1 unit every 3 levels (1, 4, 7).
