Blade Barrier traps in the ruins
These do 30 damage a pop, if not more. They're also centered on the player rather than a specific tile so it seems trying to move away from them only causes them to hit you twice. Getting healed after moving away teleported me back onto it so surviving the damage wasn't particularly helpful either. Given how low hp is on this server, and how grindy it is to get XP past level 8, having stuff like this in the module just discourages exploration.
I'd recommend trying to have the trap be centered on a location rather than a character, and reducing the caster level of the blade barrier if possible. I understand the ruins are meant to be dangerous, but it's good to keep the server balance in mind as well. 6th circle spells on a server where the level cap is 10 are a bit much.
These are standard nwn triggers, will look into replacing them with something else.
