Hello everyone, as Sharp stated in the most recent post about server development, Mythic Mob development for the server is in need of content and players able to fill the gaps.

So, to that end I'm posting an example mobfile for players that want to play around with the plugin.

If you want to try it out on a free server, I suggest doing a free trial on https://server.pro/ as you only need to do an hourly captcha to refresh it, and it's an otherwise good and free platform to test your plugin configs.

The plugin can be downloaded here but you can use the "plugin" button in Server Pro, if you do make a server, and it will install it for you.

I only have TWO caveats for making mobs if you do use this template.

1. Keep your idea of a mob's lore consistent with its mechanics, making a mob that is immune to suffocation or fire damage because a player might cheap a mob with them is the very LAZY way to do things and makes for UNINTERESTING and IMMERSION-BREAKING mobs. If it's a zombie, immunity to drowning MAKES SENSE and is fine to use, if it's a humanoid mob then it doesn't .. unless its somekinda mer-creature.

2. When developing skills, please, please, PLEASE, PLEASE!! DO NOT give the mob an unavoidable skill that hits players, unless there is some kind of AoE visual effect for a radius the skill is affecting. The WORST thing you could do with mobskills is to make a mob that randomly uses an unavoidable skill that teleports the player, or otherwise does something to the player regardless of their skill level, and actual ability to dodge. If you are going to play around with skills that push or pull players, I suggest you take cues from retro video games, that use charge-up and particle effects that telegraph the effect is about to happen (like a wave of outwardly expanding ripples for a shockwave skill).

Or shoot me a DM and I can help you develop some cues for players to use to avoid the attack, and methods for attacks to be accurate enough without being OP.

Mobs can be given skills to overcome player cheaping tactics, like the ability to break specific blocks that the mob is inside of when it takes damage, or the ability to use a one-time waterbreathing potion when it takes drowning damage. Skills can literally be whatever you imagine.
