Have the devs even done a delve? Or is it just accepted that his target radius is astronomically far too large.
For example: Doing Fungal Folly w/ the NPC who asks you to fish in the Hyper Compressed Ocean. If Brann is on the platform with you, his target box eats LITERALLY THE ENTIRE PLATFORM. Save a /tar command, the hardest part of this delve is literally targetting this stupid globe.
Compound this issue on top of targeting candles, or air filters, or experience boosts, or anything within a 10 yard radius of him.
Fix his target raidus.
