I am playing a warlock (Fiend patron, if it matters), and am trying to avoid some of the common min/max-ed stereotypes since they're likely to imbalance my party of beginners with unoptimized builds. As I am nearing level 3, my Pact Boon selection is coming up. I was thinking through ways of making my character interesting while not overwhelming the group. Since I'm not a Hexblade/melee warlock, Pact of the Blade seems like a good choice then - but summoning a weapon I'll rarely use might be a little too underwhelming.
Would it be gamebreaking to homebrew it slightly so that a warlock may perform their ritual on things not usually considered melee weapons (e.g. a key, a potion, a spellbook)? Stuff for an emergency if I was captured, or things that the party might want to smuggle or hide from scrying.
The ritual would still take an hour, I would still have to hold the item for the ritual hour, it couldn't go further than 5 feet from me without a ritual to unbind it, and the item would replace the ability to conjure a pact weapon while it's bound. The “must be magical” requirement would likely be relaxed to help the utility of it.
Naively, it seems like it could make for some interesting roleplay and be only slightly underpowered, but I feel like I might be overlooking a way it could be abused.
