This is my system that I made to prevent WC3 from crashing when units without str / agi / int buys tomes. The system works by triggering the stat increase if the buying unit is a hero.
Try buying the blueish agi tome with the peasent and you will see that WC3 crashes

//====================================================================================
// Tome System
// By Gwypaas
// About:
// I made this system to prevent WC3 from crashing when units without str/agi/int bought
// str/agi/int tomes.
// How to use:
// Create your tomes and base them of Manual of Health but with 0 health bonus or remove the bonus things all together
//
// Create a trigger, then inside of that trigger use:
// function RegisterTomeType takes integer id, string whichStat, integer increment, string SpecialEffectPath returns nothing
// id = The item id that you buys from the shop
// whichStat = Which stat it should increase, "str" is strength, "agi" is agility and "int" is intelligence
// increment = How much the stat increases when the item is bought
// SpecialEffect = Which special effect that is created upon tome usage.
// An example of how to use it:
// call RegisterTomeType('I001', "agi", 10, "Abilities\\Spells\\Human\\CloudOfFog\\CloudOfFog.mdl")
// If you wants to give the gold / lumber it costs back make sure that GIVE_RESOURCES_BACK is true and then
// use RegisterTomeTypeEx( <Same as before>, integer goldCost, integer lumberCost returns nothing
//
