Then explain me how Flash, BS, MR and HP don't contribute to survival? What is survival in your eyes then?

I dont see any "survival" items here.. Just some hp from RoA and MagRes from Lichbane

I play morgana differently than this that's for sure. But the darking binding before level 10 really, really hurts/harasses the other players. Just a thought but I normally bounce between tormented soil and dark binding until level 6. Then power up dark binding to full and it should be full at level 9 which then gives you level 10 to get your black shield before leveling up soul shackle at level 11. If you start off with tormented soil by the time you have your first soul shackle you can tear through waves no problem and this makes you a really great CCer early game. You only need level 3 tormented soil to fully kill the row of casters in a minion wave and bring the melee down to about 10% health. But after tormented soil is level 3 and you power up that dark binding people will run from you for sure. Good build though, I do like. :)

Just my personal opinion, I normally don't take Black Shield til mid game (depending on my lane lineup) and I lvl Bindings with Tormented Soil to increase the root duration. I try to harass with Soil so I keep the Mana cost reasonable while you only have your starting items. Great guide though, + rate.

Soul Shackles > Tormented Soil > Dark Bindning > Black Shield

thats your priority you say? Soul Shackles is only every 6th level so it should be Dark Binding - Tormented Soil - Black Shield

Why Dark binding? if you cant have them snared enough in ur tormented soil it doesnt matter how high ur tormented soil rank is... not to mention Cleanse, flash and the like! And ofc lvling Dark Binding up makes ur burst higher, other than that the build seems really decent...

but i would drop lichbane and get Rylai's instead, more survivability!
Just a tip though, everyone have their ways ofcourse ;)
