PContest is best place for RANKING up, not leveling characters.

Check out the thread below but best answer is Spark of Battle (Sages Tower > Flame Sprite Village) because it gives a GUARANTEED 1*Soldier Arcana for only 8ap plus gives decent exp to the whole party and rank.

Spark of Battle gives 56.25 Rank Exp per AP spent for ranking up. PContest gives 75:1.

However Sparks also gives the best character exp because of the enhancer. It's also available much earlier in Sages Tower instead of 2nd to last area of Story 1.
