Yup, beat the spider with malee, just whack away while eating grass.  :-)

i've decided to just complete the game, don't wanna bother with gecko hunting anymore.
dragon god imo is the easiest demon. u just need to survive/avoid the impact. firstly turn to your right towards the rumble.
clear the path ahead of you, or survive/avoid dragon god's slam.
continue towards the pathway and u'll see a machinery. activate it to shoot dragon god. it's hp will reduce to half.
repeat the same sequence on the opposite side.

try to avoid the impact. if still cannot try some level grinding to increase your physical defence. i suggest visiting other levels. the shrine offers good souls for grinding.
