Long story short i wanna make an explosives expert That is more heavily focused on explosions, demolishing structures and long ranged artillery then other alchemists, and essentially modifying a crossbow into a makeshift grenade/rocket launcher.

I think i got the core idea down but i would like some ideas on how to proceed, and before anybody asks the idea is to set up a bunch of pellet of fuse grenades set a delayed or remote bomb in the middle of them and set it off to cause a chain reaction blowing them all up at once. Plenty to bring down most structures.

Are you locked into a specific race? Half-Elves and Humans can start with EWP, saving you from burning your level 3 feat on it.

I'd get tanglefoot bomb or glassfoot bomb at some stage to stop enemies running away from your tower of doom. Think of them as Poetry Appreciation boots.

Problem, takes a full round action, and even rapid reload its standard, meaning i would have to wait every other turn to fire it until i got crossbow mastery It would take too long.

So, take Crossbow Mastery. A Launching Crossbow is still a Crossbow.

Another option would be to take Explosive Missile. Regardless of the regular rate of fire of your weapon, with Explosive Missile, you put a Bomb in your ammunition and shoot it as a Standard Action.

I'd spend some time thinking about the best way to destroy stuff. I think you should probably take the Master Craftsman and Craft Wondrous Item Feats.

I like the whole Sapper thing, but completely focusing on something that, in all likelihood will be very difficult to set up, is a fool's errand.

Why would literally any enemy allow themselves to be baited into your traps?

Who leaves their position to go "see what that noise was" in a world that has invisible enemies?

How are you going to set up all your fun things when you don't have time to prep the battlefield?

Thus the grenade-launcher? Maybe focus more on that, given that it is likely to be used far more frequently. Buy or craft an Ioun Stone for EWP

if you want to be able to stockpile explosives (so you can add one to every bolt and maybe also as explosive tags) i would consider taking the "Explosive Calligraphy" discovery. as it work like explosive runes and those have permanent duration. (i took two levels in rogue for the "Cunning Trigger" talent to set them off, this let me fold them or cover them to prevent untimely explosions).
and since they work like the spell. anyone standing close enough to read doesn't even get a save! (the debate is ether in same spot or in 5 ft range, save is mentioned for 10 ft)

It occurs to me that if you really want to be good at demolishing structures, you could just play a Titan Fighter with a level in Living Monolith, take Shikigami Style, and get yourself an Adamantine Sledge Hammer. You will inflict 12d6 Damage/hit, and you will ignore the first 20 points of any object's Hardness. The progression of Vital Strike Feats can get that up to 48d6. Take Master Craftsman and Craft Magic Arms and Armor, and turn your Adamantine Sledge Hammer into an Adamantine Maul of the Titans, and now you will do Triple Damage vs. inanimate objects, so, 144d6 Damage vs. inanimate objects. I guess you should take Greater Sunder so that when you smash someone's weapon or shield, the residual damage will go to the wielder, who will probably evaporate in a red mist.

Get yourself a Lyre of Building, and 1/week, you can emulate the labor of 100 men working for 3 days in 30 minutes: enough to undermine a castle wall? Definitely!

I get the aesthetic of sneaking up and planting demolition charges and blowing up the bridge, but I'd hate to see your demolition expert get outmatched by a Bard with a Lyre of Building or a guy with a hammer.

To press on with your demolitions Alchemist, there have been a lot of good suggestions already. Some might not have been mentioned yet:

I haven't looked at it too closely, but the Bottled Ooze Discovery might yield from the list of Oozes a monster that could dissolve a lot of your targets with Acid and stuff.

The Promethian Disciple Discovery lets you can build Constructs. There are a lot of Constructs that are great at destroying building and stuff.
