What's the difference between the devil curse, plough symbol and refining symbol in the fox demon matchmaker?

Similarities: they are all runes. Difference:

1. Demon Mantra: After casting spells, Villa Royalty can cause extensive damage to four enemy targets, and its output effect is stronger than that of Royalty, but it needs magical power.

2. Plough symbol: the auxiliary skill of Wangquan Villa, the effect is to summon shields to protect the body and resist the output and attack of enemy targets.
