Rotom values

[latias1001]

I have 3 questions about rotom.
To make it legal:
Should I check the "fateful encounter" box?
What should its 85h be?(in diamond)
In platinum, is it caught at level 20 and in diamond/pearl is it caught at level 15?

1) No.
2) 09.
3) Platinum: Level 20 | Diamond and Pearl: Level 15
Good luck.
