Add damage trigger and ability?

[Black-Hole]

Can someone make a trigger that increases damage of a tower by 25, and every time they use it make it cost 5g more (Starts at 100g)

So if the tower starts with 25 dam, it will now have 50 than if they use it again 75.... so on and so forth.
If there anyway that it will only effect that one tower that would be the best! and hopefully they will be able to use it unlimited times on any tower.

Also since none answered my other post can you please tell me how to put a Jass Script into my map. Im new to jass and i cant figure it out.

Can't you just make an ability that does what you want, takes x money from you when it's cast, and sets x=x+5?

Extract the war3map.j and open it in JassCraft. Then, you can just add the triggers under endglobals, and make sure to add any globals you need below globals.
