items and energy attacks

[Scion]

I cant find it in the srd, can anyone tell me what the various multipliers are for different energy types on objects? I know that some are half, some are quarter, some are the same and each special case is adjucated by the dm, but which is which?

If it is in the srd somewhere I must be blind today and it is pretty important currently while away from books ;/ bah

Acid and sonic do full damage. Electricity and fire do half (and don't forget to apply hardness too). Cold does 1/4 (and hardness applies here too).
