The Lake

Rina Evergreen Essence worked pretty well in these kinds of situations. The disciples from the Glazed Lake were successful immobilized without getting injured. 

Every time Seth saw those skills, he realized how useful they were in a combat where you didn't want to kill a person and couldn't use the overwhelming difference of power between him and the target to pressure him down. 

On those kinds of targets, the energy suppression wouldn't work as intended, only letting a physical suppression as an available option. That's why her skills were so good. 

The attack power of those blades of grass paled in comparison with what an Orb of Darkness was capable of, but Rina was able to easily resolve the situation, easily stranding those disciples inside her cocoon of grass blades.
