penalties on tanglefoots and alchemist's fire?

[pylfer]

So it came to my mind that I have a wizard that does not have proficiency in thrown weapons of any kind (same with my monkey familiar) if I were to throw either of these items (range incriment 10) would I be taking a -4 penalty to throw it (meaning throwing it within 40ft would net me a negative of -8 to 10?). If so would me and my monkey (+6 and +4 to hit respectively) be inable to even reliably hit unatended squares (ac5 needing 9+ on d20 to hit a square)?

Read the section on splash weapons. Even a wizard is proficient.

I remember an infamous 3.5 rules explanation from WotC notes there is no non-proficiency penalty... then gives an example where a character takes a non-proficiency penalty...

Actually, I believe that's the language Pathfinder uses as well.
