In terms of his ability to fight this monster, he's completely useless.
Umm. I don't remember anything like this being said, but my memory is fuzzy about this game, so I'll defer to you. Still, he has healing magic, and those wards. Plus, if zombies or something wander near he can almost certainly help wih those.
And at the very least he's another potential target for the creature. Instead of a 50/50 chance of it taking us, it's a 33/33/33.
You mean, groups like the army it was created/summoned to destroy?
No. Or maybe. Pretty much, I'm just wondering if it works like normal horror monsters, with the "As long as it's a lone person, they're not safe.". Or at the very least if a higher percentage of groups who went in came back then pairs or loners. Probably not, but it can't hurt to ask.
No, no we have not. Which is why I suggest telling him that since Order magic apparently does nothing to the creature and he is likely far less capable in forests than either Omo or us, he should stay behind.
When was it said that order magic doesn't work on the creature? Regardless, the -only- disadvantage of taking Eko is that we can't use obvious necromancy. The only spell we were going to use is steal vitality, and if he gets curious about that, we can tell him GG's story.
Speaking of, I don't think we should tell that story yet. We don't know if Eko will join our group, and it could be risky to tell it now. I think it's a good idea if Eko becomes a long-term companion, but not before that's been proven. Also, it would just be a terrible idea to say we're a necromancer before testing the water. For all we know, he might have lost family and friends to zombies, and just assign all that hate to necromancers.
