From my experience participating in the Oriaka Light guild battles, the 90% off event offers an incredible opportunity to boost your guild’s strength without spending too much. The guild battles, such as the Dragon Tiger Fight (騰虎闘) and the intense guild summits with dozens of players (like the 男ディー★コロ and 夏雪冬花 guilds mentioned), really test both individual skills and team coordination. During these events, focusing on securing key zones and maintaining steady resource gain (+600/min) is essential to stay ahead. The mention of equipment locking and phantom magic indicates that preparing your gear beforehand greatly affects your performance. Also, using the guild list and timing your attacks during the battle intervals (like the 00:12:52 match time) helped my team adapt strategies on the fly. Reward-wise, the summit victory yields large-scale guild funds (measured in billions), which are critical for upgrading team stats and abilities. I recommend regularly checking team details, such as individual hero power and team synergy, to fully utilize the 90% OFF offers and boost your guild’s war capacity (戦力). If you’re new to Oriaka Light or guild battles in general, joining a strong guild and actively communicating within the team forum can significantly increase your chances of winning. From coordinating attack times to deciding who occupes key bases, teamwork is what ultimately brings the rewards home.
