level first more and get frozt Nova and buy much magic Dust.
Make against him Nova frozt and attack normal. then make more nova frozt and get magic
Dust . that one more one more .... unitel he is dead.

There is a much easier way. u need to be lvl 13 and have pyroblast, polymorph and cold
blood. activate cold blood and use polymorph in the same turn. then use magic dust and
cast pyroblast. little foot cant attack u when hes a sheep, and when u cast pyroblast, ull
hit a critical hit cause of the cold blood, which is like a 1600 hit, enough to kill
little foot.

frost nova then cold blood pyroblast (keep trying it because i had the same problem)

to kill him you need heroic strike , cold blood frost nova and magic dust then activate
cold blood and frost nova then while he is frozen hit him with heroic strike keep doing
this until he is dead

killing him reqires sheep, polymorph, cold blood, and pyroblast and do it in that order
(my spell ranks were in the 100s)

use polymorph on him, then use some magic dust, activate coldblood, and shoot pyroblast.
Epic fail to littlefoot

u need polymorph,pyroblast,magic dust,and cold blood
