/*MINE SWEEPER by Farnham
spell detonation 54355 ktory povodne triggerovala mina nedava knockback a ani dmg hracovi, npc okolo dava,
zmeneny na spell Landmine Knockback Achievement 57064  ktory da na hraca auru Landmine Knockback Achievement Aura 57099, stackable 10x
pridany knockback cca podobny (range) ako na videach z offi + provizorny dmg, da sa nahradit fireballom
povodny spell detonation je zachovany lebo ma perfektny efekt vybuchu a dymoveho efektu
detonation ale spawnuje landminebunny 29397, bude to vidiet aj v combat logu, ktoremu som prehodil extra_flags na trigger, invisible
