to mods: I know there's all in one topic but there's 1100+ pages of posts... so don't be kidding -----------------------------------------
After establishing powerful mana farm and getting 100k+ max mana what is the best way to kill approaching mosnters? They all have 100k hp minimum and the gems do mere 200-500dmg.
uber-gemmmed* grade 11+ prismatics, in traps-at least for levels with all 8 color components. for other levels, mix supergemming dual gems with supergemming junk gems (made with whatever the level has).
*I've made prismatic gems with over 100k max tower damage. uber-gemmed simply means a very, very powerfull supergem.
But of course, as the monster hp increases exponentially, and the fastest damage increase you can do (once you're above grade 8 gems or so) is linear, you will eventually be overwhelmed....and don't try beating all 500+ waves. the 228 waves on last level are near the border of impossibility.
