I'm trying to write a litrpg and one of the main feature is skill merger.

Depending on the skill, a skill merger can happen anything between 1 to 9 times one at a time or at all once and only maxed proficiency skills are eligible for skill merger.

The new skill resulted from skill merger will retain its previous properties and effects whole also getting new properties and effects.

So here's the problem I'm facing as a result of max proficiency skills can be eligible for skill merger. It kinda slows down that skill merger a lot.

A character will have 6 skill points per level so at level 9 they will have like 54. Which resulting in slow skill merger but many skills.

So is there any solution for this dilemma?
