There has been alot of questions about getting hms in this server and the thing is there is none. It all goes off you trainer level.
Trainer level can you be increased by:
Leveling up your pokemon.
Winning battles vs other players/npc trainers/gym leaders
A list of Trainer abilities you can obtain are as follows
25: Surf (Just walk into the water and you will become a swimmer)
30: Rock Smash
More abilities could be added later. Check back for updates!
