Hylotl are a peaceful race... so it doesn't really make sense that one would go around blasting creatures with a brain extracting gun, only to toss away brains considered inferior. So, how about an alternative method of getting the Superior Brain that doesn't require random chance, fits race lore, but is somewhat more difficult to accomplish? Maybe a superior brain guarded in an Apex laboratory, or the inactive robot head within a Glitch castle. both guarded by hostile NPCs the player has to defeat, instead of picking on random animals. Yeah, its something of an inane suggestion, but it would be more immersive as it would be possible to stay in a character. For those who don't care about staying in character, it would be less tedious to actually find the stuff instead of farming monsters.
