Thanks for the help, but I'm having trouble finding out how to do the process on my own.@Cefiro: Encounter Slots determine which Pokemon appears when you Sweet Scent/walk into shaking grass, etc. For example, let's say I want to catch a Tynamo in Chargestone Cave (B1F). Tynamo appears on Slots 10 (Lv27) and 11 (Lv27) on that floor. Therefore, I would look for a PID Frame which yielded one of those Encounter Slots on RNG Reporter, under Method 5 PIDRNG. Then, simply advance your PID Frame by viewing the summary of a Chattering Chatot (1 advancement per view and highly recommended) or by saving (1 advancement per save).
Remember, (Target Frame) - (Initial Frame) = Advances Required.
So, if your Target Frame is 80 and your Initial Frame (calculated by clicking "Calculate Initial PIDRNG Frame") is 45, then you would perform 35 chatters/saves.
Having a Synchronizer as your lead Pokemon increases your chances of acquiring your desired nature and is a real time-saver. Natures listed in bold print on RNG Reporter's Method 5 PIDRNG list means that they will change based on the nature of your Synchronizer.
Do I go to Time Finder or not? I tried that and it seems like I can't set IVs if I want to do this...
Is there a guide anywhere to do this properly? At this rate I'm just going to end up chattering until I get lucky (which is actually what I have done to 5 Pokes already...)
