To evolve Graveler in Pokemon Platinum, go to any Pokemon Center. Go upstairs. Go to the second lady at the counter. This gets you to the Union Room. If any other person [besides the creepy lady in the corner] is in there, talk to him/her. Do a pokemon trade with them. Trade Graveler with the other person's pokemon of their choice. After the trade, Graveler will evolve. Trade back the other person's pokemon and Voila! you have a Golem! Note: You cannot battle or trade with the creepy lady in the corner. She has no pokemon.
you need to trade it then trade it back
Graveler only evolves when you trade it with someone else. It evolves into Golem. This makes Graveler one of the Pokemon that can evolve at any level.
If Pokemon Tower Defense is like the real Pokemon games with the evolution system then you will not be able to evolve Graveler by leveling, you will need to trade with someone (If you are able to trade)
Get a Graveler and trade it in any Pokemon center
