So young worm, you what to know some tricks to keep adventurers from gaining advantages in your lair.
Here is a couple ideas. Some will have drawbacks.
1. Adventurers can run and charge at a moments notice. Never let you lair be too flat. According to table Hampered Movement
bad surface cuts movement by half, very bad by a fourth. Every five square raise or lower by a foot. With short adventurers like halflings you will be giving them a cover bonus against your breath but the lack of speed will make up for it.
2. Now you have small 5 foot square pools in your lair. Fill them with water or oil. Just remember to relocate your more damageable possession.
3. Save those chests you emptied the contents out of. Fill with rocks or lead and place around the likely approaches. Small chests, bags, large chest what ever keep placing on the floor until they become obstructions. Plus imagine their surprise if they make a hit and run and carry off a bunch of rocks. They will think Charlie Brown was a genus.
4. What do you need with light sources. Darkness and fog will cut their movement by half.
5. Fly adventurers are a pain. A weighted net will bring them down. Plus stirges can be help full
6. concealment remember the best non magic light source is bullseye lantern which only extend out to 60 feet with a 20 cone at end. So with varying amount of darkness the adventurers miss chance goes up. Include the spells of darkness and remember most dark vision only gives them 60 feet. deeper darkness is great and you can use your blindsight to great affect.
7. Toss rocks and boulders at them especially if the rock have spells cast on them.
8. chests or pots of snakes are great missile weapons. Have your minions collect them for you.
