The core plays a very significant role in the game. Even the same character, when equipped with different cores, can have a huge difference. Therefore, it's best to carefully match them. Below, I will tell you what the method for choosing cores in the Misty World is. If you still don't know how to match cores for your characters, be sure to follow my steps. The following will bring you a detailed guide on how to choose and match cores, so take a quick look.

1. Core Selection Guide:
1. If your goal is to stack attack power, then in most cases, it is recommended to prioritize one fixed and one percentage as the optimal choice.
2. In PVE dungeon mode, the output units should prioritize stacking attack power, without needing to consider crit rate and crit damage.
3. In PvP scenarios, output units can carry crit rate attributes depending on the situation, but it's also necessary to ensure reaching 100% crit first, otherwise, it would be too unstable. After achieving full crit, you can continue to stack attack power, or directly use the dual attack setup from PVE dungeons.

4. For support units, you can consider matching cores based on your resource situation and the support team's need for tanking and healing. For example, using fixed health, armor, or output cores. One thing to note is that since the improvement from support cores is relatively small, and the cost of improvement is too high, it's not particularly recommended to specifically cultivate support unit cores.
5. For pure buff-type support, carrying fixed health and armor cores is sufficient, but there's still no need to deliberately cultivate them.

6. The selection of cores for tanks is more complex. The pairing of tanks is influenced by the different characteristics and damage types of the BOSS, so the impact of different characteristics is quite significant. For example, you need to consider whether the main source of damage is normal damage, partial percentage of health damage, true damage, etc. Here are some common tank core pairings: Lifa with two percentages, Ashilika with two percentages, Weak Water with one fixed and one percentage, Lulura with two percentages, Lilith with one fixed and one percentage.

The above is the guide on how to choose cores in the Misty World that I've brought to everyone. When pairing cores, make sure to base your choices on the character's role. Additionally, even for output characters, it's not necessarily all about stacking attack; you also need to choose based on the combat scenario.
