Vampire's big move can be purified or mercury, so can Iron Man's big move, Mogan's big move can still be ignited, weakness can only be purified, and nightmare and card big move cannot be solved together. Picheng's big move can also be done. Small fish can only recruit mercury, which is a little annoying. A big lock-up trick like Nightmare Card in Picheng can't be purified, but it's like Mogan's weak light.
Generally speaking, purification is suitable for team battles, and mercury is suitable for small-scale encounters, but after all, the price of mercury is there, and it is better to have a fever in the middle and early stages. This skill is only suitable for continuous output, and others are not recommended.
