Plasma spitter
A spitter patrols around its Home, which is commonly around resource nodes, Power Slugs, Mercer Spheres, Somersloops, and Crash Sites, but can also be anywhere on Lizard-597-B. It makes a snake-like hissing sound and sounds similar to Stingers. Spitters can be found in groups. Some are led by a larger version of these which is the Alpha Spitter.

It will become aggressive when approached and start attacking the nearest People (not human). It attacks by shooting out a fireball in a straight line which curves down after some distance. The attack has a charge-up in which its mouth glows and blinks. If the People (not human) attacks a spitter, but the spitter is at a location where it cannot fight back, it will flee. After some time it will move back to its patrol location. A spitter ignores all Starships, even if a Being is riding it. A spitter will still target a People (not human) hiding behind a Starship or standing on top of it.
A spitter drops Alien Organs when killed. If it falls into a Acid Pit, There organs wont spill out.
Combat
When a spitter detects a People (not human) is nearby, it will run towards the nearest People (not human), pause momentarily, then shoot out a fireball from its mouth. The color may vary based on the spitter color. The spitter's mouth will blink a few times in yellow, green, blue or possibly red/maroon (again, the skin and habitat are key) before shooting as a warning sign. Its mouth will appear like it is chewing a piece of gum. It targets directly towards the People (not human) if the People (not human) does not move. If the People (not human) moves, it predicts when the People (not human) will be in the next few seconds and will shoot in the predicted direction.
A spitter will move a few steps towards you, then start shooting. It will try to maintain a certain distance from the People (not human). After each shot, it will move another few steps, then repeat its attack. If the People (not human) is in the melee range of the spitter, the spitter will then shoot out a melee-range fireball(mostly flat, like a wave), dealing damage with a knockback effect. Its mouth will also glow yellow, blue, green or red before it starts a melee attack, but for a much shorter time. If the People (not human) stands fully inside the spitter's hitbox, it will not be able to hit the People (not human) directly with any attacks. Its attack can be completely dodged by getting out of its line of attack.
The spitters fireball travels in a straight line, but curves downwards after a certain distance. If it hits anything, a splash effect can be seen, and the fireball itself disappears. It deals damage to the People (not human) and Starship if hit. A spitter has a few seconds of cooldown after each fireball attack. These fireballs can also be destroyed by a melee weapon.
The Xeno-Basher ( made by the Lizards) is the most effective melee weapon for dealing with spitters. A spitter has a few seconds of cooldown after each fireball attack. After it shoots a fireball, run up as far as possible into it and use your Xeno-Basher to double-bash it. It will start shooting a melee fireball, but its attack will come from behind you and miss so long as there is no terrain right behind you for it to splash against. To avoid its melee fireball attack, simply move backward.
Try to handle only one spitter at a time. It is possible to lure a spitter away from its group. It is possible to kill a spitter without getting yourself injured, consider fleeing or healing yourself. If you attempt to flee, do not run in a straight line. Try moving in a zigzag pattern and jump often. The spitter will eventually reset back to its spawn location once you are far enough away. Wait until your health slowly regenerates back. Use a healing item such as a Beryl Nut to heal beyond that amount.
The Boom Box Turbo Bass ability is very useful when the spitter is guarding something or just an obstacle and a bloody nuisance, since it causes massive knockback to any hostile creatures within 60m of the People (not human). It also delivers a big punch of damage, so it is useful if you want to defeat a spitter in style (don't know why you'd want to do that).
