It all started with this silly idea of stacking Tiamats. Since the passive of splash damage is not unique, stacking would be a possibility. I know I am not the first to come up with this idea, but I had never seen or heard of anyone actually trying this. Then, I had to decide which champion I wanted to try this with. I decided to use Tristana because I figured that weakening surrounding targets with the splash effect would allow them to be easily wiped by the Explosive Shot.

It worked.

I do not yet think that it's an exceptionally powerful build, but it was very funny. I only wish that I could have finished the match, but three enemies ragequit, so the other two surrendered.

I've tried it, and it does not work very well because it is not cost effective. The cost of a tiamat is around 2300. Two would cost more than an infinity edge, frost mallet, or bloodthirster.

Having 3 was pretty silly, with 150% AOE damage. The game ended well before I could get 4.

Another problem is that tiamat sucks as it is currently.
