Hey, Hovde? I couldn't help but be reading over your post on Fallout and notice some... well, things we can work on.
First of all, keep in mind you're wielding superpowers! Do you think a scalpel or a grenade for that matter are going to seriously hurt Superman for instance?
Generally speaking, any blade will be hard pressed to hurt a pokespirit wielder unless wielded by another pokespirit wielder. (A blade is only as powerful as the strength put into it.) However, blades will also break fairly easily if used on something as durable as a wielder either way.
A grenade will only do very mild damage to a pokespirit wielder, and grenades are pretty rare considering it's the post-apocalypse, so nobody is going to have all that many of them. Maybe a few, but that's it. You'd need at least a dozen to seriously injure a pokespirit wielder, presuming none are dodjed, shielded against, or the pokespirit wielder is not particularly bulky or capable of powering up their defenses.
Lastly, have you noticed your posts are just one big block of text? Content is good, but your posts would look much prettier if you split the text up into multiple blocks.
Me, I personally put text in it's own mini block everytime someone talks. It makes posts very easy to read, like so.
It's rather simple. Basically you write out what your character does or says just like any other post, but you leave space for the other person's character to react to what your character does. You should never control another person's character without their permission.
So you don't want to type too much in a single post, lest you accidentally control the other RPers character.
