I'm having trouble finding many helpful guides on the spawnmob command of Essentials. I'm hoping it's not just a weaker variant of summon. First, I understand that it needs a target indicator in a command block. Is there any way to get the command in a command block to spawn a mob or mobs at coordinates? Second, is there a way to give mobs potion or other effects? The uses of the data tag that I've found so far are somewhat limited - making sheep blue, giving villagers professions, deciding what armor mobs are wearing, etc. Bear in mind that I'm in Bukkit 1.7.2.
