Here are some things you do not do in a roleplay.
Godmoding; 1. To seize control of characters other then your own at any given point within an rp without permission, and cause them to do things their owner had no say in. Bob steps on their back, laughing as they fall, and bites their neck rendering them helpless. 2. To act as if a god within rp, to entirely set up the roleplay around your character and make its life easy in many aspects, Lary gives Bob herbs, Bob is healed.
Powerplaying; 1. To avoid, ignore, or null hits within a fight to your character, can have many stages of severity. Bob dodged the attack, slashing at their throat, Bob dodged the other lion's attack unfased. 2. Healing quickly within time constraints that are not possible, may also be classified as godmoding, this is the point the two terms merge depending on opinion.
Mary/Garysue; 1. A character who portrays many perfect traits and no downfalls. ie Beauty, Immortality, Magical abilities, etc. Bob was the most powerful lion ever. And his mate was the most beautiful lion in the entire world. Whether or not a character fits under this is entirely up to opinion, and the way the user rps said character. You can have these traits and balance them, and not be a Mary/Garysue.
Autohitting; 1. To take actions upon another character and not wait for them to acknowledge said actions upon them. Bob slashes across Lary's face, causing him to bleed.
