In Soulkeep, numbers don't always trump courage, and this is what I understood very well while playing a level. At first, I was used to placing many towers everywhere, but I noticed their impact wasn't significant, and the Fiends were just passing by as if nothing had happened.
Until I started to change my mind and decided, "Why not try relying on a small number of towers, but with extraordinary power?" This prompted me to decide to use two Gloom Owl towers side by side. They aren't the cheapest towers in the game, but they are truly worth every energy point I spent on them.
After placing the two towers, I began upgrading them one by one. Indeed, the difference was very clear. After upgrading, these towers now have extraordinary attack power, and whenever a new Fiend appears, they can be eliminated in seconds. They also have a certain intelligence, targeting the most dangerous enemies first, which gave me greater control over the course of the game.
Instead of needing five or six weak towers to cover the path, now I have only two that do the job and more. This also saved me resources, allowing me to use them to strengthen other elements in the level.
The lesson I have learned from this experience is that you shouldn't depend on numbers but rather on efficiency. One strong tower can make a bigger difference than three useless ones. It's all about planning and intelligence in the battle as to see map and put upgraded towers in good positions.
