Tips to Maximize Free Rewards in Marvel Contest of Champions
Free rewards in Marvel Contest of Champions (MCOC) play a crucial role in summoner progression, allowing players to upgrade champions, unlock mastery setups, and compete effectively in Alliance Wars. To maximize these resources, it’s essential to use free units, catalysts, and shards strategically, ensuring optimal long-term benefits.
Optimize Free Units for Maximum Value
Free units are best saved for mastery cores and revives, rather than spending them on premium crystals with low drop rates. Investing in Willpower, Parry, and Dexterity through mastery setup significantly boosts champion survivability. Additionally, using units for energy refills during limited-time event quests can accelerate progression, unlocking valuable 5-star shards and rank-up materials.
Smart Resource Farming and Champion Upgrades
Efficient arena grinding is the best way to farm battle chips, which can be converted into units for greater flexibility. Prioritize catalysts from Alliance Quest milestones and solo objectives, ensuring you have enough to rank up your strongest champions. When opening crystals, wait for featured champion rotations to increase your chances of acquiring high-tier characters, optimizing your roster for endgame content.
