Heart of the Night

It seems the Beacon didn't provide significant bonuses. In the initial version, it grants a small amount of stats (a decent amount, if I'm not mistaken, 4-8 magic stats), but this doesn't make it overpowered. Later, the bonus was removed, and this is mentioned in the header. However, the non-functional resurrection is disappointing; I used it to revive a Rakshasa.

But in the final, last battle, there are different creatures, not the remnants of Karlam's forces after the battle with Baal – there are a different number of them, different upgrade forms, and no machines :( So, losses in the battle with Baal are not important.
