A kwestion (or 2)

1) With FA, you only boost the damage with cold arrow. Now, Ice arrow adds nothing but freeze length of course.Now the arreat summmit sez that Freeze length drops to .5 seconds in hell. The question is : Is this hardcoded, or does it increase with added points in Ice arrow? In other words, is the Freeze length reduction in Hell based on a formula, or is it fixed? It would be unfair to those who boost Ice arrow if the value is, in fact, hard coded.
2) Your guide points out that a decent sized mana pool is useful. Seeing that FA costs about 20 mana for each bolt, I can Totally see why

So what IS a decent sized mana pool? Should I make this TOTALLY item dependent, or can I boost Energy a bit? Your build seems to leave some room there, but I am not sure. In my build, since 1 energy point adds 1.5 mana, I put two levels in energy to add 15 base mana pool points.
I ask this only since most players seem to feel that it is a sin to boost mana with statpoints...
Merlin, the happy Charge striking wizzard.
