barrows

Can some one give me a good guide for it? thanks. and will fire blast be ok?

The one on tip.it seems pretty informative - http://www.tip.it/runescape/?page=barrows_guide.htm

Fire blast is fine, I used it every time I went with no problem.

Cheers +rep

This one on zybez.net is pretty good aswell, http://www.zybez.net/minigames.php?id=2

I'm going back, just got 80 bloods, what ya think -.-?

minds etc... -.-

I usually take around 85 bloods but to be safe go with 100 bloods, then after a few trips do what suits you best.

Another day,and is the chest random?

yes
it is unfortunately (sp?)
