    xpgain()
            if (hp <= 0)
                usr.xp += rand(20,100)


I have a problem with the XP situation. I used the above code to gain exp and I see the limitations as I cannot embed a value. eg. usr << "You have gained [gainedxp] XP!".

Please could someone help me with this. I am still learning so please bare with me :P

You can't expect us to understand what xpgain() is for with just this information alone. I'm going to assume xpgain() is called each time you want to detect something's death. A much better alternative would be define who the attacker is:

mob/verb
     Attack(mob/M in view(1, src)) // select mobs in a 1 tile-wide radius
          M.hp -= 5
          M.xpgain(src) // src is the attacker


mob/proc
     xpgain(mob/attacker)
          if(hp <= 0)
               var/expgained = rand(20,100)
               attacker.xp += expgained
               attacker << "You have gained [expgained] xp!"
