Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

Because I have armor that has +1 Constitution, and a belt that has +3 Constitution, when I log in and they re-equip themselves I take 26 damage right off the bat. Why is my character taking damage when I equip something with a con bonus? Please stop it. Remember, there are WEAPONS that have Con bonuses on them, too. Like The Iron Corporal in the Blushing Mermaid shop. I want that weapon, but I don't want to take 1 damage per level every time I equip it.

Well, you answered it yourself — have only 1 item with CON bonus at the time, no other solution is possible. It's an anti-exploit script afaik, preventing endless HP gain.

I can't help that the only mithral plate I could find had +1 con. Also, what about weapons with + Con? If I get that nifty cold iron morningstar +4 with +Con I'm going to take damage every time I equip it. Can't we just have a script that, when we equip something with +con, check to see if the character already has something equipped with the same or equal con bonus and if so, temporarily remove the con bonus from the new item?

In the meantime, could a dm please remove the +Con from The Iron Corporal in the Blushing Mermaid Tavern shop?

You could catch a DM in-game and ask to remove the con bonuses, that's possible.

And if I were you, I'd do it sooner rather than later, as I've died from that multi-con item script.
