Orcs – discussion about the race.

15% chance that the spell will fail;

45% chance that the enemy's magic will be reduced by 2 times when calculating the spell's effect;

the same chance (45%) for doubling the spell's cost;

15% chance that the goblins will be pushed back to the beginning of the attack turn order, and if it has a cursing effect or deals damage, it will affect the goblins, and the caster will not spend mana.

antonag07 How did you calculate that?
Honestly. I'm just too lazy to look it up in the description.
If you've already found the formula, could you write it down? How do the percentages of spell blocking depend on the number of goblins and the level of the caster?

Using the formula (caster level + spell level + 17) x 25, it turns out that to block the control of a 15th-level hero, you need 925 goblins. If there are 500, then the probability of blocking should be (500/925)*100% = 54%.
Why did you get 15%?
