upon spawning in get the Ruby Crystal. DO NOT build any armor or magic resist until you know who is in the top lane with you. From then on if you are facing AD, build armor items like Sunfire Cape and Randuin's Omen. If you are facing AP, build magic resistance, such as Banshee's Veil and Spirit Visage.

Once you get the two items that are going against who you are facing in the top lane, start building opposite items. For example, if you faced an AD champion and built armor, start building a Spirit Visage and Banshee's Veil and vice versa. You should be mainly focusing on minions and farming them for your W, but you should still push and take tower. Also, if you have a chance for kills take them.

At this point you are now a pretty good tank. Your main focus now is to just bait out other champions ults and protect your team. Chances are you will not get many kills, but you can get a lot of assists, and this is actually good for a tank. Also, being a tank, you should start diving towers and be the person to split push, since they will need to send more than one person to take you out, especially if you have Thornmail and Sunfire Cape. A lot of people say that you need a good kd. This case is quite the opposite late game as a Tank. You are in the role to protect your team at all costs, unless it will result in a double kill. Also, during late game, DO NOT FORGET TO KEEP GETTING CREEPS FOR YOUR W.
