Well, I'm not impressed. I need to go and find out how to make this look a bit better.
See you after I've worked out what I'm doing (hey, if you can tell me how to duplicate the "classic" monster statblock, I'd be grateful...)
Encounter H1: Spider Lair
Encounter Level 2 (600XP)
2 Funnelweb Spiders (F)
2 Spider Swarms (S)
These four rooms are thickly festooned with spiderwebs. The floor of rooms 11 and 12 has largely collapsed, leaving a 1 square margin along the outer walls. All the spiders are hidden at the start of the encounter. Check the characters’ passive Perception against the spiders’ Stealth checks.
When the PCs open the door, read:
It is difficult to make out the original walls and floors of these rooms, so thick are the spider webs. It is clear that the original ground floor ceiling has collapsed and you can dimly see through the webs to the next floor beneath/below.
When a funnelweb attacks, read:
A spider the size of a large dog appears from a nest near the ceiling, firing a jet of webbing at its hapless prey below.
When the spider swarms emerge, read:
The webs across the room suddenly come to life with tiny spiders that swarm towards you, attempting to scurry beneath your armour and consume you from within.
The spiders keep hidden until a character enters the room, whereupon the funnelwebs will attempt to attack with surprise, entangling the lead character, pull them up to the ceiling and consume thm at leisure while the swarms overrun the remainder. The funnelwebs are not used to prey that fights back and will retreat across the roof if bloodied, the swarms will fight to the death.
Features of the Area
Illumination: During the day there is dim light from the broken windows and collapsed roof. At night the area is dark.
Spiderwebs: These squares are difficult terrain, and characters must make an Athletics or Acrobatics DC10 check or become immobilised. Escape requires an standard action (Athletics or Acrobatics DC10). All non adjacent enemies have concealment. Falling into web squares halves normal damage.
The webs are flammable, if exposed to flame the webs will burn quickly, spreading by 1 square per round and consuming the web behind it. Any creatures in a burning web at the start of their turn or entering it on their move are attacked (+4vs Reflex; Hit 2d6+2 fire damage; Miss half damage)
Bookshelves: These can be used to climb between rooms 2 and 11 with an Athletics check DC10. If the webs are set alight the scrolls and books will be automatically be destroyed.
