- Battle Royal system against other players/servants
- Summon powerful servants to fight alongside you
- Reward from the Holy Grail granting powerful gear and buffs
🏆 Holy Grail War Mechanics
Every few days a grailwar will start that you can join. The grail will announce to you when its time to join.
To join a grailwar you need the followings:
Quite a bit of gem shards, obtained via mining, to craft mana gems

A valid summoning altar setup
This can be created by drawing a 5x5 area with chalk and the altar in the middle. Right-clicking it will then activate it.

Filling this altar with mana gems and then right clicking it once again will start the summoning process after which you will now be a part of the current grailwar. You will be granted 3 command spells when joining which have various use cases. Other players are also able to join this way.
During a grailwar enemy servants without players might also spawn in case these slots are not already filled up by other players.
Defeating all other servants will award you with the holy grail.
Pressing [H] with a summoned servant allows you to take control of them in various ways such as attack targets or movement patterns.

Servants have their own mana pool which will be used for nobel phantasm but you can also use up one of your command spells to immediately command them to use it.
Command spells also can be used to give your servant a temporary buff.
⚙️ Configurations
The mod is highly customizable via the standard config files. You can e.g. configure the amount of participants in a grail required to start a grail war or the max amount of participants.
Additionally changing attributes of servants or the loot tables the grail provides is possible via datapacks. For this please refer to the wiki for more information.
