It's interesting how to take the red resource node on level 111 with Shakti, using the starting army?
In total, about 160 troglodytes. Let's say only two stacks came to Shakti, so we have about 120 troglodytes. We upgrade them. From the third hero, we take a diversion in the form of spearmen, gremlins, or whoever else comes and single units. The red dragons will be afraid of the attack stack of troglodytes -> they will take damage three times.
The result of the battle is that the diversion dies, and the entire stack of troglodytes remains intact. Then we build the summoning structure on level 112 in the castle and have two fronts :)
