Whis seems to spawn in a few fixed spots in Saiyan Battlegrounds , not randomly across the map. The best public breakdown I found says there are four Whis spawn locations , and a recent video discussion also points to Whis being part of the game’s fusion/update content.

Spawn spots

  1. Near the edge of the map by the big mountain area.
  1. Outside on the left of the city , around a corner area.
  1. On a rock in a chill/open spot near the third area.
  1. Below an overhang close to the third location, with Beerus spawning above that same structure.

How to find him faster

  • Server-hop if he is not at any of the four spots.
  • Check the mountain edge first, then the city-side corner, then the rock/overhang area.
  • If you see Beerus above a structure, look underneath it too, because Whis may spawn below there.

What this means

The info currently available suggests Whis is a location-based spawn with a small set of known points, rather than a full-map random NPC. That makes the hunt more about route checking than waiting in one place.

TL;DR

Whis in Saiyan Battlegrounds appears to spawn in four fixed locations , including the mountain edge, left side of the city, a rock area, and under an overhang near where Beerus can also appear.
