I've been playing in a campaign as an Oracle of the Lore Mystery for a few months. I've saved my party's hide a few times now as the only healer, but as the party gets stronger they need healing less and less, and I'm beginning to see that I'm not really an effective character for anything. This is likely because I'm pretty sure I botched my ability scores.
STR: 12 DEX: 13 CON: 11 INT: 15 WIS: 15 CHA: 20
I'm a level four now, and the more I try to help the party when they don't need healing the more I mess up and just waste turns, to the point where I actually left a combat to check on a door in the other room we hadn't tried yet because I could do absolutely nothing to help the party. We were fighting dire rats. DIRE RATS! Is there anything I can to do to make my character helpful to my party? Any spells I should try and get? Could I double class into anything that could make use of my ability scores? Essentially, what do I need to do to be better.
