Level 2? 27 Destroyers? Looks like you had a lot of mana :).

So, the total amount of damage he dealt was 35345 HP.
This is equivalent to, for example, 1767 Succubi, which is 185,563 gold. So, essentially, the average cost of a summoned Destroyer is 6872 gold. While the actual cost is 490 per unit. Of course, you summon them for free, but the numbers show how expensive it is to use the portal...
