Mot it's not really concerned with the exact topic, indeed.

From things you've mentioned, I'd pick sneaking as the first thing. Hard to implement but very useful. And of course needs detailed work-through, like "will other mobs that didn't see you react when you stealthy kill one of them" etc.
Also I'd suggest to implement some pole vault equipment for longer jumps.

PS My opinion: keep on more realism and less OP stuff. Please choose realism instead of super-hero stuff like levitation :)

I think more realism/less OP stuff like toomanynights said would work.. but sneak/sneak attack would be cool, as in you sneak, which makes it so most mobs (most) can't see you, and a sneak attack could be a multiplier to the weapon you're using (Only multiplying damage if the mobs don't see you) er something like that. I just woke up so don't mind me if I sound tired.. x3

@Taylor620 Yeah, I didn't mean sneaking to be an OP stuff. Since IRL one actually could sneak and hit, it's not considered as a superhero trait for me. Which couldn't be said about flying ability etc.

cyclopes glasses when examineing it it whould say (i dont think he was a real cyclopes) and it whould be a held iteam like the spear it be ranged lazer and mayber you can save the idea for a x man mod

How about the ability to hold someone?

They should be able to resist you though. The longer they wait to resist, the longer it should take for them to succeed (Typing, or not expecting it.)

Once they break free of your grip, you can't grab onto them for awhile, depending on how long it took them to break free (Instant-break = A LONG time. Long-break = instant grab again.)

Grabbing from the front makes breaking easier, from the side the grabber get's hurt and knocked during during break, and from the back is most effective.

Breaking free, THEN holding a weapon/tool would make being able to be grabbed take longer.

Someone already holding a weapon/tool may have it snatched out from behind them if they don't instantly-break (Within one/two second(s).)

EDIT: Oh yeah, and you should be able to move with someone you are holding onto. The longer you hold onto them, the faster you can move (Up to almost full speed... but still slower to let their friends catch up to their AFK friend.)

Players should also no be able to talk while being grabbed, unless they are close to breaking free (Whisper Only mod + This = PERFECT COMBO.)

Take cover would also be interesting if it was automatic. Walking between a wall, mob, or any other object while being shot at will make it take the hit (I HATE Bishops! I need a way to easily kill them! Haha!)

Sneaking would also be useful. Perhaps for players, you would have to take a single step at a time. If they are facing you, and you are not behind an object, you become visible. Otherwise you are completely invisible.

To pickpocket, you would have to be standing behind a non-moving/turning player for ten seconds to take something they have (Or something they are holding if you grab them, ;)), or if they look in a chest, it would take five seconds.

Sneak + sneak attack and Plant explosives are the few ones that seem reasonable enough. Being able to do something more with gunpowder is always a good thing when done right.

Have you considered something along the lines of Confuse/Distract Action? One use for it could be something like: Using confuse will allow you to remove a creature's agro on you.

Another idea for more actions is Charged Attack, holding the auto attack button(F) or holding a mouseclick of Attack on a creature will hold an attack pose and do increased damage upon release but it will have a long cooldown if you miss your Charged Attack.

Third idea, would be Roll. Rolling away should allow you to dodge any projectile targeted at you. It can also help with kiting Giants, but rolling more than three times in a row will trigger a long cooldown before you can roll again. Anything along those lines.

Whichever ideas you take and in what ever variation you choose to make them, thank you for taking the time to make this mod and every other mod you have ever made. Cheers!

this somehow remembers me of monster hunter.lets all dodge roll away from deerclops :D
