You can modify all those values in the config

Talisman Crafting Recipe

You can prevent abuse of the talisman by setting xp_boost_enable_level_threshold in the config to true. This will set a level threshold which the player has to reach/surpass in order to receive the talisman's xp boost. This is disabled by default. You can edit the level threshold as well in the config. (xp_boost_enable_level_threshold_value) The default threshold value is 10.

Information for Version 0.5.0+ (1.12.2):

You will most likely get the following message / warning in the console:

[Server thread/WARN] [minecraft/LootTable]: Tried to over-fill a container

This is caused by MC-91727 (fixed in 1.13+ so ¯\_(ツ)_/¯)
