- Research Stone: Research Stones are necessary for the advanced tiers of science research at your University Buildings. Research Stones are essentially another type of resource, like food or wood. The ways to acquire research stones are: Complete Daily Quests (2 stones per day), Compete in Arena of Mars (1st Place is 500 stones, every 2 weeks. Rank 200 still gives 15 research stones, every 2 weeks,) Kill Monsters after you have completed Advanced Research to cause monsters to drop stones, and purchase premium Packs in game.
