speedy spider

You can get a early lv of the passive and delay your ult a bit if it would have an impact but you are not going to be ganking you will be getting ganked.

sorry about the formatting its my first guide.
with the spiderlings you pull them back if you are under pressure like from aoe brood split pushes so you push when they are not their and you push hard.
Trainquil boots are the choice because of their move speed buff. They will be broken most of the time and are evaluated as if they where broken. The early move speed is too good to pass up.
I have never actualy needed eye so i will remove it.
You get a sange and yasha because you are already gettign a yasha and it is a convinent upgrade with the 16% move speed buff and the mini stuns can help with no stun of your own. you can also disasemble it lator to get a manta and halbrid if need be. Its also a extention for late game. Heart could be a situational if you need more hp but by that time she is allready very tanky.
I get soul ring because it allows you to spam your spiderlings before you get to 7 which means you can push as soon as posible. After you get your core you could go vlads because the lifesteal stacks but you won't be in combat much and the armor is nice but a hundred spiders is WAY scarior and will keep them away. Creep are not really pushing its your spiderlings. And haveing more spiderlings will have a bigger impact than tankyer spiderlings due to the higher dps. you also gain lifesteal with your ult so not quite the same impact

One thing, I don't honestly get is why you wouldn't put Incapacitating Bite into the skill slot of either 4 or 5. The slow chance might help with early ganks and the miss chances will definite help with auto-attackers such as Drow Ranger, not to mention unfortunate enemies might miss their chance at ganking your allies when you hit them with it.

When listing items use the ((Yasha)) or ((Drums Of endurance)) but replace all () with [ or ] respectively.

Also, spiderlings give 20g gold bounty, and any carry you are hardlaning against (because Broodmother is now a great hardlane thanks to her ability to move through terrain) will just get easy free farm.

Also drop tranquils, as a semi-carry you need gold to be effective, and every last hit will just break them. Power Treads are a much better grab adding survivability to Broodmother and you can easily get to the side shop with your invis on webs.

Eye of scadi is pointless on a Broodmother as your E already slows (better too) and gives the enemy a huge chance to miss. Combine this with a Butterfly or a Heavens Halbard late game you can normally shut down most carries (with the exception of Anti mage due to his Blink and Phantom Lancer due to his multiple illusions, unless you get the drop on him so the chance to miss means he cannot produce many phantoms untill he has Manta Style

I don't rate Sange and Yasha as it is a 4100 gold item, and yes its made of small components, you do not need the slow or movement increase. You are better saving for a Heart of Tarrasque as it will allow you to fade out onto a web, heal up and be back in the fight within seconds.

Also if you are solo hardlane, get your supports to buy you some Sentry wards and put them on the courier for you. You will be sentried on your web by a semi-compentant carry support equilling in a very easy kill on you. You need to deward to keep lane domination.

However if you want to go for early pushes, getting a Ring of Basilius would be better than a Soul Ring. Gives you better armour and mana regen as your int levels are reasonably low, can build into a Vladmir's Offering, which is great late game on a Broodmother with her ult. But more importantly it boost the armour of your spiderlings and the creep wave, but it will reduce your last hitting ability as you will be under the enemy tower.

And one last thing, look at your presentation, atm its quite hard to read, add some colour and headings.
