Question regarding siege engines.

Are there any rules on how the damage, reload , and crew requirements for siege engine are effected when you shrink a siege engine? So are ballistas in the same weapon category as crossbows? If not would it be too much to ask for them to be in the same category? Pathfinder only no 3.5 or 3party.

We don't really have any rules for how this should work.

At best, if you shrunk a ballista to the size of a crossbow I would simply tell you it now functions exactly like a crossbow. This would however be a house rule, and now you've just got a regular crossbow in terms of damage and such.

Can you provide some more detail about what you're trying to do?

If your trying to get ballista damage but able to use it without the annoying reload times and such I will tell you that such a thing would definitely be unbalanced mechanically and is simply not allowed by the rules.

So my idea is to make the siege mage archetype work. I have a lvl 7 gestalt character to work with. Was looking into how shrink item would work in this situation.

Also is it possible to create a construct siege vie craft construct or animate object? If so how do you think that would affect reload and mobility?
