I only need to burn a magic log to fully complete my Seers achievement diary and get the coveted Enchanted Excalibur. Are there any boosts that can be used, or would it be best just to go for 75? I'm 72 at the moment by the way.

You could use a stew to get your level up to 75, but to be honest, it is just as easy to train the level up now.

Getting everything you need for the stew will take shorter time than training the level three levels, but you'll probably want to train the skill later some time anyway, perhaps for the adze, or just for training it.

So, it's possible, but it'd be easier to train it. And 75 looks much better than 72 anyway, don't you think?
