Skills synergy and resistanses

The idea of the developers is that the player has to use different skills to kill monsters, but in the final, the player uses only 1 - 2 skills.

Idea : increase the resistance of monsters to a certain element from each hit they take, so that the player does not use 1 skill.

Example : player hit 1 lightning strike for 100 damage. The monster's resistance to lightning increased by 5%. The next hit will only deal 95 damage and will increase the monster's lightning resistance again.

When resistance to one type of damage is increased - resistances to other types may decrease.

The percentage of resistance can vary by different amounts for different monster type.

The increased percentage of resistance may depend on the strength of the hit and the monster's HP.
