that's the thing with heat inherit here, I let the sentinel land a hit which primes the target with heat and all other multipliers (heat mods + banes etc). So long as the first proc from the sentinel gun doesn't expire, any other heat procs with multipliers (furis in this example) just add to the lit fuse and thus will still act like it was done by the sentinel because the starting procs never dissipated. If the kills counted like they were from the furis then the procs wouldnt have spread.
