I'm playing D&D 3.5e as a human Ranger. Our party has recently had a couple of wins, resulting in some nice loot. I was lucky and got the pick of the pile both times.

The first time I got a sentient bow with some nice abilities. As I'm pretty low level and the game hasn't been running long, the DM allowed one fudge: he made sure the item would match my alignment, because otherwise it applies a negative level as long as I'm carrying it, and may refuse to help me.

The second time I got a pick from a Deck Of Many Things... and drew an alignment switch. I've gone from Lawful Neutral to Chaotic Neutral, which means my bow now opposes me (the rules state you must match the non-neutral part).

I've not had this bow long, so it seems a shame to have to stop using it already. Also, I'm relatively new to D&D, and while I get the principles I don't have anywhere near the experience of some of the other players, so I'm very aware that other characters in the party are starting to pull ahead in terms of combat effectiveness. I don't mind not being the best, but I'd like to be able to pull my weight, and this bow (and its abilities) was one of the things I was hoping to use to help with that.

What are my options for moving my alignment back to Lawful? I don't mind it taking a little while - it could make for some interesting plot - but I'd rather it didn't take so long that this bow is underpowered by the time I can use it again. The bow has very high Diplomacy (+12) so perhaps it could convince me somehow? Most of the party are Chaotic Something or Neutral Something; the only Lawful character is Evil.
