I can see throwable items becoming a thing in the future, as a starting point.
From my experiences in testing, it’s actually really cool to see how each addition was a layering of core mechanics, to bring everything together.
To achieve grappling hooks/ropes - the developers would have to expand to throwables - I’ve always thought a great starting point would be grenadas (early lit fused cannonballs for you history buffs)
Once a throwable item is added, that mechanic could be expanded on to include ropes/hooks, throwing knives and maybe even potion/mystic area of effect weapons like poison or blinding... lots of options here.
