It takes level to keep summoning, you can't keep a level 100 summoned monster if it's level 1.

When Gewalt summoned 《Ifrit》to fight the black dragon, he was having difficulty, and suffering from pain because the level of 《Ifrit》  is much higher than his at that time.

But in the case of a slave, you do not need to spend mana to maintain it and can command them even if your level is lower.

So far I haven't seen Kurm being able to defy Diablo's orders.
