What it does

Each attribute has a base value plus modifiers. base set changes the base, base reset restores the default, and modifier add <id> <value> <add_value|add_multiplied_base|add_multiplied_total> stacks a named change you can remove later. Attribute IDs have no generic. prefix in current versions, for example minecraft:max_health or minecraft:scale.

Good to know

Needs operator permission level 2.
