It would mostly be Trouble for Renko since it's kind of completely focused on him; it completely ignores one of the NPCs in the game in favor of attacking him, in spite of the fact that he's much more heavily-armed. Any destruction will probably be limited, though, since the temples are constructed of unknown materials that (I assume) would be too strong for the tick to break. And Renko will probably get right on training it to Not Do That once he gets it chilled out a little.
