Editing Sufficiently Advanced Magic/Summary (section)

== Chapter 21 - Venom ==

After Sera recovers a little, Corin discovers that Derek's "return ring" is actually a [[Ring of Derek Controlling|control ring]], and that Orden has been trying to prevent Corin from completing his mission. When Corin calls her out, she explains her role as one of Tenjin's kidnappers and her future plans, and Vera explains that Echion is a test subject with a God-Beast attunement.  When the conversation goes south, Corin, Vera, Sera, and Jin flee through a room with a giant spider. After defeating the spider, the next room is full of fire breathing statues. Sera drinks Corin's [[Attunement Primer|mysterious attunement liquid]], starts glowing, gains a massive amount of ice mana, and regains her voice. When checking her mana level, Corin realizes that her attunement has completely changed, but without any increased capacity. They then go through the flame room and down the staircase into the room where they are supposed to meet Katashi, as Orden appears in front of them.
