Running a Clientsided Hook on a Player in a Server Sided Function

[EFEX03]

Hey, I know I just asked for some help, but I need more! I had asked earlier for HUD text to appear and disappear for EXP gaining. The code is flawless, but I am not sure how to run the hook for the hud text on a player in this case:

function ENT:OnTakeDamage(dmg)
local woodcuttingskill = dmg:GetAttacker():getChar():getData("Skill_Woodcutting")
if !IsValid(dmg:GetAttacker()) or !dmg:GetAttacker():IsPlayer() then return end
--if woodcuttingskill <= 24  then  dmg:GetAttacker():notify ("You need atleast have level 25 woodcutting to chop this!") return end
    if table.HasValue(SWM_CUTTING_TOOLS, dmg:GetInflictor():GetClass()) or table.HasValue(SWM_CUTTING_TOOLS, dmg:GetAttacker():GetActiveWeapon():GetClass()) then

if CLIENT then
hook.Run("HUDPaint", "draw_xp_gain", XP.drawGainNotification)
end

end

Below is the HUD EXP gain function that I have in my HUD file (which is client side only ofcourse!):
local XP = {}

XP.alpha = 0

XP.GainNotification = function(gain)
    XP.alpha = 600
    XP.gain = gain
    hook.Add("HUDPaint", "draw_xp_gain", XP.drawGainNotification)
end

XP.drawGainNotification = function() if not (XP.alpha > 0) then hook.Remove("HUDPaint", "draw_xp_gain") return end
    draw.SimpleText("+ 500000 EXPERIENCE!@!@#!@#!#!@", "ChatFont", 20, 20, Color(230, 230, 230, XP.alpha))
    XP.alpha = XP.alpha - 15 * FrameTime() * 10
end

Use Net library to send a message to the client server which will replace the usage of hook.Run
