	When a Class Reset is performed, it resets the player's stats based on their current level among many other factors. Since the base stats are altered by these skill boosts, Class Reset effectively ignores them when calculating the new skill values, but keeps their effects active on the player. For example, the Skeleton Key gives +40 Security, so if the player Class Resets and picks Security as a minor skill, Security could for example be reset to 39 (it is based on player level and will not always be this value.) However, since the base stat is now 39, and the Skeleton Key is still on the player, the player currently has a +40 Security boost for a total of 39 Security, meaning that if the player then drops the key, they will lose 40 Security, resulting in a final total of -1. Skills are unsigned 8-bit integers, which means that they can only be a positive value from 0-255, so a value of -1 is interpreted as rolling backwards from 0 to 255. This is what results in the final desired effect of skills underflowing to a very high value.

			found something, if we decide to use dlc content, greenmote can be used to fortify personality, speed, endurance by 10 base which we can remove with level scaling glitch so we could start with base 15 personality and maybe we have enough to underflow speed now
