How can I increase the damage a mob does in Minecraft Bedrock?

[rosemadder]

I'm making a backrooms map in bedrock and I'm using the silverfish as a hitbox for the entity. Although the silverfish moves fast, it doesn't deal enough damage to the player. How do I fix this?

Give the entity strength with the /effect command.

/effect @e[tag=TagOfTheEntity] strength 99999 [Effect level 0-255] true

At the end of the command, change true to false if you want the player to be able see the effect particles.
