Suppose there's an everyday ordinary human character who becomes invisible, either due to quaffing a potion of invisibility or from somebody casting the invisibility spell on him. These cause both he and the gear that he's carrying to become invisible.
While he's invisible, can he see himself? Can he see the items he's carrying that are invisible with him?
The plain reading of the "invisible" condition would say "no", as he is "impossible to see without the aid of magic or a special sense". There's nothing in either the potion or the spell which says it gives such aid, so since effects generally do only what they say then it looks like he can't.
But on the other hand, I'm trying to figure out how that would work in practice, in both a narrative sense and if there are any game mechanical implications. For instance,
- It'd be harder to watch one's footing on rough uneven terrain, so perhaps it would be even slower going than usual, or some dexterity checks or saving throws might be called for.
- It'd be harder to swing a sword or aim a bow. Mechanically, attacking a creature that can't see you grants you advantage on the attack, but I'm having a tough time picturing it really being easier to attack if you can't see what you're doing (particularly for some weapons like a bow), even if the opponent isn't seeing it coming.
- It'd be really hard to find a particular item among one's belongings. For instance, if I had two different potions in similarly shaped containers, I might not be able to quickly figure out which one was the specific one I wanted to find.
For those reasons and others, I'm thinking that allowing a person to see themselves and the invisible items they're carrying may make things a lot easier (and more fun), even if it's not supposed by a strict reading of the rules.
So, my questions:
- Is my reading of the invisibility rules correct, that rules-as-written one can't see oneself when invisible or one's carried invisible items?
- Is it "typical" for a DM to treat this as a downside of being invisible, such as by making it take longer in combat to be able to get out a desired item?
- Is there anything I need to be wary of if I decide to make it a house rule that people can see themselves and their things while invisible? I'm assuming it doesn't make the invisibility spell overpowered or anything like that, but there may be something about the tradeoffs the designers have in mind when being invisible that I'm missing.
