Almagnus' suggestion is good both for collecting a lot of relics to either combine and meld into better relics or refine for shards and for farming a wide variety of legacies. You don't really need to worry about the latter until you're closer to the level cap, but it's something to keep in mind.
If you're not allergic to the store, buying extra LI slots is actually a decent investment.
