Summon! My Summoned Creature Is a Little Too Fierce

I was only messing around with a summon after the System tricked me into it. I never expected all kinds of outrageous things to show up: Ninefold Nether Hounds, Thunderfrost Behemoths, War God Venom Dragons… I really don’t want to be a gambler, aaah!!! Wait, you’re a summoner, so why are you charging straight at me and pounding me? Because I’m afraid my summons will beat you to death if I let them attack!
