Alchemical Items?

[Viladin]

Greetings from Spain

A few questions?

1. The alchemical items, the attack is vs AC, vs touch AC, or DC fort as the spell?

2. The alchemical items level 2, do 3d6 +6 (web) or 5d6 +10 (pdf)

3. As the cost calculated?

thanks

1. Touch AC, but if it has a save, requires both.

2. 5d6+10

3. Not sure I understand the question. Rephrase?
