Before the rework you get 400 less mana Currently you get a max of 4 with 1900 mana if you play right you can have maxxed farms at wave 15, 25 waves for mana you get a total of 5600 mana (solo) 5600 times 25 is 140k. A maxxed sci is worth 17k ish. You can buy 8 scientists and still have 4k. (Is banned, according to the meme) dog witch lowers cost by 40% and slightly decrease damage by 2% Scientist cost would be 11k ish instead of 17ish you have low cash count, you normal get half of the hp of enemy you kill into mana, so you would have little mana, also it's ability makes it increase a tower count. But costing 100k, that would only work if you had lemonade (not allowed) or wait for boss wave, (meme says: you must have it)
