The commands named on the Modrinth page of Altar SMP Arc 1:
/boneblade/bonealtar/bloodlust/bloodaltar/frostscythe/frostaltar/vulcanaltar/wandofillusion/illusionaltar/weaponhandle/vulkanhead/wardenhead/illusioncore/removenearbyaltarsThis plugin is a replica of the Altar SMP Arc 1 plugin (which adds Boneblade, Bloodlust, Wand of Illusion, Frost Scythe and Vulcan's Crossbow + all the items needed to craft them and their corosponding altars.) This plugin lets you recreate what you see on the proper SMP.
It is very simple to set up since it has zero dependencies so all you need to do is put the .jar file in the plugins folder of your paper/spigot server. Please make sure everyone is using the texture pack as well (it only works if the clinet is on 1.21.4 or higher). Get the texture pack in my discord in the plugins channel.
If you have op you can do:
/boneblade
Gives you boneblade.
/bonealtar
Spawns the bone blade altar.
/bloodlust
Gives you bloodlust.
/bloodaltar
Spawns the bloodlust altar.
You can change the bloodlust kills, the bleed chance, the bleed time and bleed damage in the config.
/frostscythe
Gives you the frost scythe.
/frostaltar
Spawns the frost scythe altar.
You can change the damage of the frost scythe projectiles in the config but it does depend on the difficlty of the server a lot.
/vulcan'scrossbow
Gives you vulcan's crossbow
/vulcanaltar
Spawns the vulcan crossbow altar.
You can change the power of the fire ball in the config but it does depend on the difficulty of the server a lot.
You can also change the damage of the normal vulcan's crossbow's arrows.
/wandofillusion
Gives you a wand of illusion.
/illusionaltar
Spawns the wand of illusion altar.
All the mobs are configurable in the config for when you transform into them. By deafult flight is disabled for all of them since I felt this was a bit op but you can change it if you want.
Example of what one of the mob's config looks like:
The transforming in to players and mobs looks a bit weird becuase I made my plugin spigot not paper so ye.
So far for per mob custom abilities I have added:
Warden - sonnic boom attack, damage and cooldown cofigurable in config
Enderman - throw a pearl, cooldown in config
Elder Guardian - Gives nearby mining fatigue, cooldown in config
Ender Dragon - Fire a dragon fireball, cooldown in config
/weaponhandle
Gives you a weapon handle.
/vulkanhead
Gives you a vulkan skull.
/wardenhead
Gives you a warden head
/illusioncore
Gives you an illusion core.
/removenearbyaltars gets rid of nearby altars.
If you don't have op:
You can craft the weapons at their corrosponding altar spawned in by someone who has op.
You can craft the wepaon handle with this recipe:
You can craft the vulkan skull with this recipe:
You can craft the illusion core with this recipe:
Kill a warden and it will drop a warden heart.

Make sure your server runs Paper and Spigot on Minecraft 1.21.
Download the .jar file from Modrinth and put it in the plugins folder of your server.
Restart the server. Avoid /reload, many plugins do not handle it well.
Type /plugins in the console: Altar SMP Arc 1 should be listed in green. Its config files are created in the plugins folder on the first start.
