The "Chipadin" will max the Holy Fire skill and try to get as many pluses as possible to that particular skill. The Holy Fire skill give a strong enough fire damage pulse at high skill levels that it can usually kill act 1 normal monster in a single pulse, even when they are spawned in a game with a higher player count.
you said you searched it on google? did you try clicking, i am feeling lucky?
pretty much a chipadin is a chipped gem farmer... he can kill low monsters in one easy pulse, then just max vigor and run around looking for chipped gems
not very viable because a perfect gem = 81 chipped gems
so if you were on ladder, you could make one of them, and get 324 chips for a high rune
Players used to use 3x chipped gems and an elite type sword in cube to roll a cruel prefix mod with three sockets. It no longer is viable tho as new runewords out damage the best magical mods.
