EoM UB- Basically a road block build
You are playing like a bully Blood + 1 helm build, which is to try and make them run before you use up too much mana to control flags and lanes, while making them miss XP/Gold from creep waves.
The advantage is you can be spitting for free early on when uncontested on towers to stay in the lane, or you will have another spit grasp combo coming up when everyone else is out of mana.
At some point, the builds that take blood will need to buy a bigger helm, and you'll have a window of opportunity to bully them as well. Your life is always going higher, while other builds will have a pause in life increase while the buy mana items.
Basic strategy
EoM -> Grasp -> Spit -> Activate Ooze
Mix the above order up a bit, or spit once inawhile without EoM to be unpredictable in order to prevent an interrupt or wasted EoM
Buy banded at the start and save for Unbreakable
Than buy whatver, but I usually go
Banded
Unbreakable
Nimoth
Hauberk
Bloodstone ring
That is +2500 life over base
The choice after is usually one or the other
Sell Bloodstone ring to pay for Groffling Plate (Life + Armor)
or
Sell Banded for Narmoth's Ring (higher life + 11% life steal)
Don't try this in a laggy game, you need responsive skills and EoM to get this off properly.
