This mod allows you to make PvE with command blocks!

(I think also it is able to create PvP. Also good for modpacks, it is all up to you!)

 

This mod provides:

・Custom Potions can be used as enemies' actions.

・Options to change aspects of entity using scoreboard tags.

 

You can include this mod to modpacks or just use for your modded server. Be careful that this mod itself does not add any boss, you have to create them!

For documentation and usage of this mod, see the github wiki page.


Features

・Custom damage potions which can be applied with any integer damage (unlike vanilla damage pots, it can deal from 1 to 127000 damage)

・Damage potion which ignores invincible time (can be used to attack continously)

・Fire/Poison/Wither potions with configuable dps

・Damage buff/debuff potions can be applied to increase/decrease damage entities deal/recieve (physical damage and magic damage is separated so it works better with some magic mods! Also the amplifier can be modified by 1% units)

・An effect allows to reset invinsible time

・Allows to give entities more resistance by setting Effective Health parameter (it can only be up to 1023 in vanilla, but this feature enable to give more)

・Allows to give entities more melee damage (same as health)

・Player shaped entity (I recieve any requests with your skin!)

・Entity with boss bar


How to use

1. Install this mod by putting jar file in your mods folder.

2. Open the world.

3. Create what you like by using features on your own!


Player Skins

There is Player shaped model data, so I can create player shaped entity with your skin.

Player shaped entities currently available:

white_garden (Creator: mikokonoGuilatti)

cutecute (panda) (Creator: Cutecutebethoven)


If you want me to add player-shaped entity with your skin, please let me know as a comment!

(22/7/2023) Added a Google Form to request addition of your skins. Please fill in This and submit that!

(28/4/2025) I am sorry to say but maybe it took some (can be infinite) time to make mobs cuz this was what I made 2 years ago and I do not actually remember how to tackle with this mod (I am creating a brand new RPG mod, so stay tuned!)


Fun fact: This mod was originally created for modded server played among my friends. One command enginner created challenging bosses with this mod and players fighted using power of other mods.
