29. Yes. Obsidian Guidance potions (from the crown store) will allow you to apply xp to skills faster. There is also a 3 day blessing which does this, but it's difficult to get. (It's in Lost Vale.) I think there are some semi-rare food items like Lord British's birthday cake or something that also give a bonus. Also, while exact formulas are unknown, the amount of xp applied from your pool to a skill is affected by the size of your pool. Many people will keep at least a million in their pool at all times to take advantage of this. I usually don't let it dip below 10 million. Higher level players probably keep even more than that.
