@Unknown555: your weapon overheating affects your damage, so you just gotta take a different - slower - weapon. I got a golden gun, which drains about 15% of my weapon dmg a second.
Try being life itself with forest scorpions, queens, which make bioluminescent critters, who provide light for Rustlers, which gives you about 50-70 quantae a turn when you have 30 fireflies. Add empathic bond six times for 150 hp regen a turn and you'll be immortal!
ummm guys... if you use a heal scroll at the moment you die, your HP goes under 0, heal you for x% and then your HP bar says undefined/undefined ? wiiierd.
