ZenSummoning Examples

Once a Summoning Info is registered with the Summoning Director, it will be available for players to use.

To perform a summoning, the player must insert the reagents into the altar and activate it with the catalyst in their hand.
Alternatively, the catalyst can be dropped above the altar and a redstone signal applied.

Players can look at the usage of the altar in JEI to see available summonings.
Looking at the recipes for spawn eggs will show summonings that include the mob the egg is for.

Example summoning 1

Summons 4 cows and 10 blazes
- Spawns the blazes 8 blocks above the altar, +/- 3 blocks in each direction
- Spawns the cows 4 blocks above the altar, +/- 3 blocks in each direction
Consumes 1 stone, 12 eggs and 1 stick as catalyst
Doesn't work in the rain
- If it's raining, displays a custom message
- If it's successful, displays "Woohoo!"
Gives the mobs custom NBT
- 1.16 renamed generic.maxHealth to generic.max_health.
