TokenEnchant Explosive - way too large?

[PurrfectMistake]

Hey, im trying to lower the odds of the explosion occurance and im also trying to lower the amount of blocks it destroys.

Currently, the pickaxe im using has explosive 100 on it, and when it "explodes" it breaks a lot of blocks - https://prnt.sc/khwo7j

This is my current config:

Spoiler: Config

    Explosive:
      max: 6000  # the level of Explosive will be used as the radius of explosion.
      price: 10
      radius: 1  # radius
      use_explode_event: true
      # you can set the multiplier to calculate the total amount of blocks to be exploded
      # level 150 and multipler 2 = 150 x 2 blocks within the radius 3 will be exploded
      multiplier: 0.5
      # you can nominate the world, which prevents explosive
      invalid_in_world:
        - plotworld
      # you can turn on automatic pickup.
      pickup: true
      # you can turn on automatic smelting
      smelt: false
      # you can turn on/off explostion sound/visual effects
      effect: true
      # you can turn on/off explostion sound effects
      sound: false
      # You can set the occurrence of explosion.
      # random: randomly occur based on the level
      # always: explosion occur always.
      occurrence: random
      use_explode_event: true # use efficient explode event.
