Originally I was planning on calling this the "Tele-Raper" since that's sort of the idea with this .. but I suspect that would be censored out. Tele-Stomper? Who knows.. the name is largely irrelevant. Hopefully the run down of this build will give you some new tactics for your demigod games and make your opponents scream in frustration.

Level 20: Foul Grasp II or Improved Attributes
Spit loses effect later in the game if there are multiple characters that can remove this affliction, and in a match with Multiple Sednas or Erebus you may wish to replace levels 11 and 16-19 with improved attributes. Early game spit is still useful even against these characters. Plague is mainly for preventing use of the Heart of Life and is imperitive to get this as early as possible. Level 20 is really open, though Foul Grasp upgrade seems the most useful as long as there is a mana flag on the map.

Always keep teleport scrolls handy for assaulting demigods attempting to take friendly flags or towers. Mana should no longer be an issue once the heart of life is obtained, though it might be a good idea to carry combat mana potions just in case you fall short of using an ability during combat. This build specializes in one on one combat. Fighting multiple demigods will prove extremely difficult as UB has no means of healing himself. The key to success is to get your enemies alone and grasp them after you've turned on ooze and applied spit, to prevent them from using any escape/healing abilities or moving off the acid pool. If your enemies have specialized in movement, you may wish to drop the scale mail a little earlier for boots of speed.
Hope that helps ^^
