Skyshayde, give yourself a Froslass. Since you can't obtain a Dawn Stone until very late in the game, don't bother with the Snorunt stage; skip straight to Froslass.
When you get all of your Pokémon together, pick any Pokémon other than Froslass (I'll refer to this Pokémon as X from here on to save space). Froslass has an unnatural connection with X - she is the physical representation of X's soul.
Froslass' nickname must be the species name of X. X and Froslass must always stay together; if X is in the party, so is Froslass, and if X is in the box, Froslass must be boxed too.
Froslass is bound to X, so takes on X's abilities. She may only learn or use a move if it shares a type with either Froslass or X.
Finally, if either X or Froslass faints, their counterpart becomes impaired; they've had a part of themselves knocked unconscious, after all. Until you heal at a Pokémon Centre, both X and Froslass may only use moves of the primary types of each partner.
Summary:
Froslass
- Pick any of your other Pokémon, referred to here as X.
- Froslass must be nicknamed whatever X's species name is.
- If X is in the party, so is Froslass. If X is in the box, so is Froslass.
- Froslass may only know Ice and Ghost moves, along with moves that share a type with X.
- If either X or Froslass faint, the counterpart can only use the primary STAB of each partner until healed at a Pokémon Centre.
I really hope this makes sense, can't tell if my explanation is clear enough. Just in case, I've included a couple of examples:
Example 1:
Shuckle is chosen as Froslass' partner.
- Froslass' nickname is "Shuckle".
- Froslass and Shuckle must stay together at all times.
- Froslass can only use Ice, Ghost, Bug or Rock type moves.
- If Shuckle or Froslass faints, their counterpart may only use Bug and Ice moves until you heal at a Pokémon Centre.
Example 2:
Houndour is chosen as Froslass' partner.
- Froslass' nickname is "Houndour".
- Froslass and Houndoor must stay together at all times.
- Froslass can only use Ice, Ghost, Dark and Fire type moves.
- If Houndour or Froslass faints, their counterpart may only use Dark and Ice moves until you heal at a Pokémon Centre.
