Proof -> http://terraria.wiki.gg/Lifeforce_PotionI don't think the life force potion existed when this thread was made. Also that still only brings the player to 600 if you have full life fruits.
I say "still" even though 600 is an overpowered amount off health as it is.
Actually the life-force potion was introduced in 1.2.4 which released over a year before this thread was posted.
^ This. The major issue with increasing total health is having to do all kinds of balancing.I don't need to say yay or nay, because thankfully this will never happen. Oops, I guess I gave my nay here.
Doubling a player's hitpoints would make normal mode an absolute breeze (more than it already is) and would make expert mode incredibly easier as well.
