It's always funny when fiction depicts someone immortal as completely unstoppable but otherwise more or less mortal. I mean if you really want to ensure the immortal person never bothers someone, just bury them. If you're buried six feet under, you're under (quick google search later) 1.3 tons of dirt. Unless you have a burrow speed or earth glide you aren't getting out on your own, even if you're the protagonist of Kill Bill.I remember reading something ages ago that, even if you are immortal, something sometime will happen that will make you wish you weren't. How many warforged have been caught in a cave in and gone mad? Something will eventually get you and being immortal will be curse rather than a blessing
I was thinking about the amount of hard drive they have to store memory. The older they get, the more things become fragmented and space gets tight. They start to delete old memory to make space. I could see an adventure where you need to find an old warforged to get some information and he has forgot it.
It's been mentioned a few times by others but it feels like people are treating it as a footnote of fluff rather than the actual mechanic it was.As I recall, warforged have a (dark)wood core, with the idea that the reason they can have a soul bound to them is that it is contained in this "heartwood" core.
As such, that wooden core is subject to rot, strain, hardening and whatnot over time. Personally, I'd put them at about 145 years of age for an average lifetime before parts finally give out and replacements can't be made for critical core pieces (essentially the "brain" and "heart").
It'd be interesting in later aeons to come back and discover "petrified" warforged whose heartwood had morphed to stone, leaving them frozen and unable to otherwise move - perhaps the fate of the Lord of Blades, who had to pass on their position to a successor, but is still consulted at times as a sort of "living statue"/god.

Theoretically they're immortal. Last session the players encountered a giant pike. This turned into how old are sharks. 450 million years they're older than trees. See where I'm going with this?
You're going to the land in which they mistake how old the general family line is for how old the individuals are?
Nope it was how old the species was. Went from pike, shark, how long sharks live to long lived individuals in D&D thinking about could they last epochs.
