I was playing a Delve last night, it was a stage where frequently an effect would happen where it says "all heroes must test x, if they fail move 3 spaces back towards the entrance. Test is modified by -1 shield for each adjacent hero".
It said "heroes" and "hero", not figures. This wasn't a peril. Would familiars treated as figures like the Reanimate, Beastmaster's wolf, etc. count in any way for this? As either having to test (and autofail), or when calculating the penalty for adjacent heroes?
RtL rules mention that Peril effects don't affect figures treated as heroes, but this wasn't a peril effect. The notation of "figures treated as heroes" is interesting though, I don't see that notation in the core rules about familiars. Page 17 and 18 reference that some familiars are treated as figures, but not "figures are treated as heroes". Is this stated somewhere else?
I also wonder if familiars treated as figures need to be adjacent to the portal to leave a stage of the delve? Whether familiars treated as figures means the figure is a hero or not would answer this question as well I think.
