[HELP]Buffing others as a char perk? Performing an action after a set amount of time?

[Banacizo]

Hello!

So, I am currently making a character mod, but I'm fairly new to this and I can't figure out how properly do this.

I want to make a few character perks that will work something like this:

1. When [Player is this specific character], all other players in [this proximity] of the player get ++to their armor.

2. If [Player is this specific character] and there is [this another specific character] in [this range] of the player, they both recieve a health regen boost.

3. If player doesnt hit anyone for [this set amount of time], his next first attack damage is boosted.

All the feedback is appreciated. Thank you.
