Platinum discipline
Morning, day, night, daily, Radar, swarm, dual-slot, static, gift, and event rows remain distinct when their requirements differ.
Route Plan
Pay the entry fee, check the binoculars for today's six special species, collect area items before the step limit, and take HM05 Defog near the entrance.
- Each area independently chooses one daily species from the source's 32-entry table. That species replaces grass slots 6 and 7 for a combined 10% encounter chance in that area.

Each area below has its own table, split by encounter method. Standard grass and cave rates merge every base slot for a species and are shown per time window: morning 04:00-09:59, day 10:00-19:59, night 20:00-03:59. Swarm, Poké Radar, GBA dual-slot, and Trophy Garden replacements keep their own labeled rows. Underlying slot odds: grass 20/20/10/10/10/10/5/5/4/4/1/1; Surf and Old Rod 60/30/5/4/1; Good and Super Rod 40/40/15/4/1.
