Leaderboard kill and Infernal Spawn Trigger

i want to know 2 things and my map will be done:
1.leaderboard when units owned by player 1 red kill 1 unit add 1 kill to the leaderbord
2.every 10 minutes create infernal in region ( this must be looking like dread lord ultimate skill : infernal spawn from sky and do littledmg etc. )

1. check tutorials
2. u can make invisible unit and make him cast that spell every 10 minutes.
Action: Unit-Issue Order Targeting A Point

Leader board triggers

variable:

E: Unit - A unit owned by Player 12 (Brown) Dies
C: (Owner of (Triggering unit)) Not equal to (Owner of (Killing unit))

A: Set kills[(Player number of (Owner of (Killing unit)))] = (kills[(Player number of (Owner of (Killing unit)))] + 1)

Leaderboard - Change the value for (Owner of (Killing unit)) in (Last created leaderboard) to kills[(Player number of (Owner of (Killing unit)))]
