For people using my pack who wants to mess around or is a developer wanting to use it for their project, here are the commands and details:

This is basically the command.

/function s_effects_lib:cmd/effect/<effect>/<modifier> {duration:<count>}

<effect> is for what effect is being used in the command, here are the availables:

• bleed
• fatal_bleed
• frostbite
• lethal_frostbite
• electrify
• stun
• eternal_flame
• rage
• infetion
• invulnerability
• batrachotoxin
• fatal_poison
• stealth
• true_invis
• wet

<modifier> is for what modifier is used for command, here are the availables:

• apply (to increase the duration of the effect)
• set (to set the effect to a specific duration)
• reduce (to remove some of the duration)

<count> so the count in duration is basically the duration of the effect.

Examples:

if you are still confuse here are some commands and what they will do:

#1

/function s_effects_lib:cmd/effect/bleed/apply {duration:10}

This command will give the player the add 10 seconds to the bleed effect.

#2

/function s_effects_lib:cmd/effect/frostbite/set {duration:4}

This command will set the player's Frostbite effect to 4 seconds.

#3

/function s_effects_lib:cmd/effect/electrify/reduce {duration:15}

This command will remove 15 seconds from the electrify effect.
