Tamer Team Building
Your squad is up to 5 partners; each knows up to 6 moves.
Stats
A partner's stats come from its species, its level, six permanent IVs (0 to 31 each, rolled when it is first met and kept for life) and EVs (up to 252 per stat and 510 in total) earned by defeating monsters. Wins teach EVs; IVs are for life. Catching pays no EVs.
Levels
Partners level to 200. Total XP for a level is floor(5 x L^3 / 4), for example 1,250 for Lv 10 and 156,250 for Lv 50.
Moves
When a partner learns a new move with a full set of six, a window lets you keep the old moves or replace one.
