Good to know, Seriously though at some point it will probably end up in a fight.Who would win 10 kobolds vs. 1 Gruen?
Also how long are ticks concerning both OOC and ingame?
Ticks: What others said.
Combat 10 Kobolds vs 1 Gruen: Too variable to tell. You'd have to be more specific about intelligence, skills, equipment, magic, etc of the participants. Specifically for the Gruen, I'd also ask what mutations it has if any and how old it is (young, mid, old, ancient) because they grow constantly while alive and can live indefinitely assuming they keep eating enough.
Note on Combat: Even an "infant" Gruen without any notable mutations should be more or less like an "adult" of another species with the possible exception of size and worldly knowledge. Also I gave Gruen the ability to spit acid but I've never actually seen it referenced in the game thread. The lack of seeing that in action leaves me uncertain of its effectiveness in this theoretical battle.
Either way like others said, you could do Death Battle Plane combat to check.
Fun Gruen Fact: Gruen don't die from aging directly but can die from starving when older. Any Gruen can eat excessively but the youngest ones can actually survive purely from photosynthesis or small food portions limited to just dirt and rocks. Food requirements grow with the size of the Gruen which increases with age or excessive eating. So as Gruen grow due to age or eating, they actually go from little or no food requirement to massive food requirement. Effectively any Gruen that doesn't die in combat will probably eventually die from starving after getting too big which "normally" happens slowly due to age but is sped up drastically by excessive eating... which all Gruen have a natural tendency to do. So most Gruen are purposely speeding up their life cycle by eating more than they need to. This is a well known fact to Gruen but almost all are willing to risk the potential early death to become bigger and more powerful sooner. The idea is that big enough Gruen earn enough power and influence in society to procure enough food. This usually works until a point when the aging younger Gruen become powerful and numerous enough to overthrow and eat the older Gruen, effectively taking their positions.
