The level range you have depends on the item you are using. Cracked red eye orbs and the red eye orb invade 10% below your level and infinitely above... (example: you can invade as a sl1 and be put in the world of a level 700 even though it is not likely in the slightest). The blue eye orb works in reverse... invading 10% above your level and infinitely down... however it only invades people who have "sin" which is gained by invading with red eyes or killing passive npc's. The cat covenant ring just makes you invade anyone in the forest that does not belong to the forest hunter covenant and has not killed the area boss.
