[b]Each binding contract lasting twice as long as it too to make, certainly it would appear as if Zande had been locked into a loop. How nasty. He may have been a cannibal of flesh, but she was a cannibal of souls. He imposed his power in the physical realm and she imposed hers in the aether. They were two sides of the same coin. He could not break the loop with magic nor wiles or endurance. In fact he'd at best be able to last ten minutes like this due to the taxing effects of the Zamorak Brew. Which was why raw strength was another matter. He had that to spare. 

Zande's striated muscles quivered and bulged, straining with obscene force as a continuous gout of steamy breath streamed from his gaping mouth in a long, gutteral sigh of effort, like a tea pot that hadn't quite boiled yet.
He could throttle a gorilla when in under the influence of his maddening, supernatural drug.
Forget ten minutes. Now that the headhunter had set his mind on breaking out of the binds, seconds might be all Tanya had.
