League of Angels > KeyFeature
- Eteral Spiral unlocks at Level 50.
- Your goal is to eliminate the Tower Guard in each stage and climb as high as you can. A new stage will be unlocked when the previous is cleared.
- After a stage is cleared, Runestones will be rewarded via prize draw.
- The higher the Spire level, the stronger the enemies will be and the better the reward you will reap. All the stages of a level must be cleared before the level can be blitzed.
Lvl. 1 to 6 Rune-leveling items can be purchased for Runestones in the Rune Shop. They are required for upgrading Runes to the specific rank.
