1) In the 3.5 Player's Handbook on pg. 93 where it addresses the "Empower Spell" feat, it means that the results of a damage roll, say 1d4+1 where I rolled a 4 on the die would be: 4+1=5x1.5=7.5 correct? If that is the case, are numbers (such as the 7.5 above) rounded up or down in regards to damage? If you multiply the result of the die roll (4x1.5=6) before adding the +1 (6=7), that would work except if you rolled an odd number (such as a 3) in which case: 3x1.5=4.5+1=5.5.
2) In order to create a rod that can replicate the effects of the spell "Acid Fog" (pg. 196 in 3.5 P.H.),for example, 10 times per day upon speaking a command word, would one use the formula: spell levelxcaster levelx1,800gp (pg. 285 in 3.5 D.M. Guide table 7-33) and then because it has 10 charges per day, divide the total cost of the above by 2 (pg. 285 in 3.5 D.M. Guide table 7-33)?
3) Page 88 in the 3.5 P.H. states that metamagic feats can be used to apply metamagic versions of spells in scrolls, potions, and wands. When scribing a spell to a scroll that has been enhanced via a metamagic feat (such as "Empower"), how much does that increase the base value of the spell? When looking at a scroll that just contains the spell "Acid Fog" for example, an un-enhanced basic version of the spell has a base value of 1,650gp (pg. 240 in D.M. Guide); so what would be the value of the same spell that was empowered? Is there no set formula in which case it is something the D.M. is to eyeball? If that is the case, I came up with the idea since the metamagic feat "Extend Spell" fits in with the regular formula for scrolls (spell levelxcaster levelx25gp on pg. 285 in the D.M. Guide table 7-33) where the spell "Acid Fog" is concerned for example, as it simply doubles the duration of the spell based on the level of the caster (say 11th), would equal a duration of 22 rounds with the feat applied (2 rounds per caster level) & would make the scribed spell worth: spell level (6)x caster level (11x2) because of the "Extend Spell" feat=22x 25g=3,300gp Thus, since all the metamagic feats have the same prerequisites (none) meaning one isn't significantly more powerful than another, that if said scroll above had been scribed using only one of the other metamagic feats, for example "Widen Spell", then that should equal the same base value of 3,300gp because the metamagic feat "Widen Spell" isn't necessarily better than "Extend Spell". In a second example, scribing the spell above (as an 11th level caster) using both metamagic feats above ("Extend Spell" & "Widen Spell") would equal: spell level (6)x (11x2=22)x 25gp=3,300gp (for "Extend Spell")+ 3,300 gp (for "Widen Spell") equals a total cost of 6,600gp for the scroll. Using this formula, the maximum cost for an "Acid Fog" scroll would be 19,200gp if it were scribed by a 20th level caster with all applicable metamagic feats applied: spell level (6)x (20x2=40)x 25 gp=6,000 (for "Extend Spell")+ 3,300 (for either "Empower Spell" or "Maximize Spell")+ 3,300 ("Enlarge Spell") +3,300 ("Quicken Spell"), +3,300 ("Widen Spell")= 19,200gp.
4) Page 99 in the 3.5 P.H. states that the creator of a scroll must use up to one-half of the base price of the scroll. Using the above scroll as an example (base price of 1,650gp), that would mean that the scriber must pay 825gp in raw material cost? That seems like a lot considering all the raw materials one would probably have to have in order to scribe a scroll being: parchment (2sp per sheet), inkpen (1sp), ink (8gp per 1 oz. vial), & perhaps a scroll case (1gp). Even in the case that a scroll such as this took more ink or more parchment, it would be quite a bit to equal the 825gp cost...
