Got close to Tinker's Top XP score through the use of Imawal (this should be the extra glyph from the prep).

I used an L3 Goblin to access the Secret Sub, yeah, it was the Zoo. But since there was an L6 Druid near there, you could also access the sub by knocking it through the walls there.
As for Frank, he definitely was in a bad spot. I could only used a few walls to the north of him after realizing I could Pisorf an L1 mob to below him and then attack from below him. Now that I think of it, there's actually an L2 Snake somewhere near the bridge and you could actually Pisorf it all the way to the bottom of Frank. That way, you can attack Frank from above towards the L2 Snake below it. But, this has to be done early (at L1 or L2) and there's no way you would know that right from the start.
