Heroes 5.5 WarGame Edition - Tactical Edition.

The new executable file allows you to adjust the healing for the tent, and you can immediately set it to a достаточно high value (without the corresponding perk, there is still no resurrection).

This is what I meant. With the executable file fix, there is a way to balance the tent and the ballista, because in the original, the ballista is almost always preferable. It's a pity that the "Extra-expert" level for tent healing is not defined (it heals with negative values, resulting in huge numbers, after which the entire stack is defeated with a single hit).
By the way, the author of the executable file fix didn't fully understand the tent.
Here are these lines in his patch, marked as "unknown value":

- &no_mastery_unknown_value 0
- &basic_mastery_unknown_value 0
- &advanced_mastery_unknown_value 1
- &expert_mastery_unknown_value 3

These represent the level of debuff removed by the tent.
