Soaring Armed Cobra

Luke heard Troy and Fiona talking, so he made a beeline for them, quickening his pace to catch up with them, and entered the next range of the dungeon where the entire team had gathered.

Rey was holding a futuristic watch with a holographic display, using it to scan a beast's tentacle, seemingly trying to gather some information about it.

"Everyone, we need to be careful," she said. Some monsters gradually develop resistance to repeatedly used strategies and powers."

As she said so, she skimmed the holographic display, then stood up.

"This dungeon has an evolving ecosystem," Rey said and pointed at the monsters they had fought recently and finished, "This means that the monsters here are actively breeding or biologically evolving in the absence of a dungeon cleanup. That's why this monster we fought has evolved from ordinary tentacle beasts to advanced tentacle beasts."
