This update is mostly a patch.
1 - The hatcherys now can't be placed near bile nests.
2 - bile sacks are now 100 poison resistant, increased from 50
3 - bile sacks now explode into poison when destroyed.
4 - the trapdoor spider eggs grow time has been reduced from 18 turns to 6 turns.
5 - web traps will now spawn outside a forts walls when spawned on one.
6 - trapdoor spiders should have a fixed range attack now.
7 - trapdoor spiders and web traps now have the stealth code.
8 - you can now spawn a portal on a plain tile for 500 enchanted weed.

Removed a forgotten piece of code i was using for the last update.
Changes - Gave Spider Hulks the trample code.
Added - new Ritual, Create Hatchery(Must be atleast 7 tiles away from a thicket and 5 away from another hatchery, for 500 enchanted weed you will be able to build one, these hatchery's pump out stupid spiders every turn, however these units are weaker than thicket spiders)
Added - new Ritual, Spawn EggSack(these EggSacks are what produce units on hatchery's and for 250 enchanted weed and being on a hatchery tile, you can spawn 1d6 of them)
Added - new Ritual, Create Bile Nest(Bile Nest's are a sort of corrupted hatchery that produces sickly Bile type spiders, these places will become future recruiting spots for any spider i make for necrotic or diseased spiders, furthermore upon converting a hatchery into a Bile Nest, you'll spawn 1d6 BileSacks on it and in the next turn any EggSacks that were present on it will convert over to a BileSack, The Cost for a Bile Nest is 1500 enchanted weed)
Added - new Ritual/unit, Summon Bile Titan(just for the low low price of 10000 enchanted weed and being on a Bile Nest, You'll be able to summon a single bile titan spider! these monstrositys are the most powerful spider's at your disposal, don't be fooled by the price of these things as they're very much worth it although i'd recommend using spiders that are completely resistant to poison if you wish to use these)
Added - Bile Spiderling(these are small greenish spiders produced by Bile Hatchery's, they have 1 health however their abdomens aren't filled with silk but rather with poison gas, upon death they will explode into poison, these spiders basically sacrifice themselves to win)
Added - new Ritual, Summon BileSack's(just like with regular hatcherys, you can summon 1d6 BileSack's for a Bile Nest)
Added - new events

Changes - When you create a spider thicket, a brood mother will now automatically be spawned on the location
Added - 2 new events
Added - Jumping Spiders(these little guys will jump about and cause chaos amongst the enemys ranks)
Added - Trapdoor Spiders(immobile stationary units, great for defense)
Added - New Ritual, Lay Trap(for 50 enchanted weed, you'll spawn 1d20 on Web Traps at your location, these traps are filled with acid and cutting through them will cause damage)
Added - New Ritual, Create Trapdoor Colony(Lay a clutch of eggs 1d15, at your location, these eggs will take some time but after a while will grow into Trapdoor spiders who will make that tile their home) ritual cost is 200 enchanted weed.

I may not be the best artist but i do hope you all enjoy :), also side note: for the new rituals, you might have to start a new game to get them.

This mod was not created by me, this is soley an add-on or an extended version of the original.
How does this mod differ from the original?
i've added 2 new events, each one has a chance of 1 like all the others.
the first event is simply 50 hunter small spiders leaving the thicket and the other can only be accessed when you're an Ancient matriarch or higher!
once you gain that, there will be a chance for a Lesser Matriarch to be born in the thicket and leave it with a few of their children in tow!
these Lesser Matriarchs will roam about all the while generating their own princesses and their princesses generate their own brood which later grow into large spiders!
unlike the player, Lesser Matriarchs aren't immortal.
i'll probably add more to this mod in the future and if the original creator wants this removed, i will do so if asked.
