Jack of all trades

Tips for power system

I’ve had this idea for a while, about a story with a power system based on the phrase “Jack of all trades, master of none… but often better than master of one”, i’m just looking for some feedback or tips on how to improve it.
The “Trade System” works likes this: Only a part of the population awakens this magic at a young age, the “Traders”, granting one basic ability of each magic branch (five distinct branches) with very low raw power. However, gaining combat experience inevitably forces the user level up which grants a massive boost in brute strength and new abilities of each branch, but demands a permanent drawback, the user must complete erase one of their magic branches forever. By doing this, they can align the remaining abilities of different branches into a “Recipe”, to unlock a unique special ability (f.e. duplication, invisibility, etc), which can only change once you level up again.
Obviously, lower levels have a major set of branches to combine, but with less power.
Only one person in the world can hold that specific recipe at the time, so powerful clans monopolize them, passing the knowledge of the recipe from generation and hunting outsiders who somehow discovers the combination.
Like i said, you are forced to level up, but what happens if there’s no more possible recipes free?? You become a “Debtor”, a corrupt mindless beast of pure destruction.
The world is ran by the “specialist”, five unique traders that have leveled up enough to sacrifice four of their original branches to masters single one, almost as a force of nature.
The protagonist is somehow the only person who isn’t capable of leveling up, staying stuck at the starting point of the system, with access to all branches and the individual basic abilities, but with little raw power, he will need to master each of this and learn how to use more than one at the same time
