Don't worry fellas I have you covered. There are built in resistances to the Siren's Call, an amulet that can be made, AND in the end you can fight the call through sheer willpower. However, to keep things realistic and challenging I will be keeping an eye on the resistance factor (having a broken heart), and who has a realistic chance of overcoming the call through willpower.
If you have further concerns please feel free to message me. I'm not going to cut anything powerful loose without thoroughly making sure that there are ways for characters to work around it. The pull goes both ways though, I'll call BS if someone randomly has a broken heart or has the amulet (which has to be made
). I don't think I'll have that problem with you guys, though.
