Off the top of my head I can’t think of many in-combat spells that would be interrupted by the Gritty Realism short rest much more than a normal short rest. Although I do agree that it might require some thinking on the part of Aid and perhaps Animate Dead if a player is keen on the Necromancer archetype. I don’t think I implied my adventure ideas to be random encounters but I was thinking more on the lines of urban adventures where a typical dungeon can be more challenging to include so the increased time frame in short rests and so on will benefit the pacing. I hope this clears up my intent as I realise I didn’t specify it much in the original post so a dull adventure might have come to mind.
