Okay, I have a table called: "monsters" and it has 5 mobs. (rows)
Only 1 is a Unique mob with a grade column set to "Unique".
The following query will select a random mob (someone entered the dungeon for their specific zone (map))
SELECT * from nrpg_monsters WHERE level >= 1 AND zone = '.$zone_id.' ORDER BY RAND() LIMIT 1
But the problem is, By this logic query, the UNIQUE mob has the same chance to spawn as all the others, lol. How would I make, let's say the unique mob spawn < 10% with this query? his id is 5.
The point im trying to make is, I use this info to insert it into a monster_active table, so users can actually kill their own mobs and level up/gain exp on my game.. I dont want users to have the same chance to spawn a unique mob as a Normal or Magic mob...
