I'm working on an HQM map and I want to add in a reason to be afraid of mobs. More fear than vanilla mobs can provide. No Mekanism, so no uber-geared vanilla mobs to ruin your day. However, I don't want to make ender pearls an impossible thing to get, which is something that most extra mob mods do by overwhelming the spawn table with custom mobs and drastically lowering the chances of enderman spawns. MFR isn't in my pack (yes, really), so Pokeballing an enderman isn't a quick fix early game option for future players of my pack. My pack will be an oceanblock or a skyblock (haven't decided which yet), so I need players to be able to build a vanilla style mob spawner and get a reasonable quantity of pearls. The starting area will be pretty big, though, so I want charcoal production for torches and night-time shelter to be an early priority. Basically, I'm trying to re-capture that "first night playing Minecraft" fear that we all had back in Alpha and I want it to persist for a little while as the player gains power. I don't have much experience with mob mods or even know what the possibilities are. Can anyone point me to some mods that add (preferably configurable) toughness and/or better AI to vanilla mobs for 1.7.10?
