Re: MF Concerns
Dropping points into strength isn't a big deal; you can get enough by simply running Rakinishu on /p8 'til clvl12. What's much more difficult will be completing the Sigon's set, or ANY set for that matter, with your first MF character before it becomes useless.
If you're that concerned with the first 30 levels, socket gems into or gamble high damage bows and stick behind an ActII merc. Safe. Your biggest test will be Duriel, but that's just an inconvenience so long as you drop TPs in his lair. Cube rings/ammys all the while looking for MF or +mana gear so that when you reach Eldritch you can spam Blizzards until clvl40. By then, you're a powerhouse.
