Can you guys who know, suggest the best tank build for Rammus? I have a huge win streak with my jungler, and I'm ready to learn how to do the thankless job of being an effective true tank. I'm looking for the build that makes it so my HP barely drops when hit so it's laughable, building to his damage dealing capability is great, if it can be done in the context of an uber tank.
The thing to being a tank is you have to be very flexible with your build. You build to counter the other team rather than follow a set build every time. Rammus however does benefit more from armor items than MR, but you will almost always need magic resist.
Here is how I build:
Core:
Cloth Armor + pots (usually I go for 3 health and 2 mana.)
Lets you play very aggressively, getting a lot more minion kills, as well as a good chance for first blood with a good DPS teammate in your lane.
Heart of Gold
Tank really benefits from extra gold/5. Later builds into randuins.
Boots
Either go
Ninja Tabi or
Mercury's Treads.
Depends on their amount of AP vrs AD damage, as well as the amount of CC they have. If it's a lot of CC no matter how much AD they have I will still go merc's. If they have a lot of AD without a lot of CC, Ninja Tabi is a lot more beneficial to Rammus.
Rammus is one of the few tanks that I do not get swiftness on as he is such a great initiator with powerball.
Giant's Belt
You need the HP, even if you don't end up building sunfire.
Other Items
Banshee's Veil
If they have decent CC this item is a must. You will not be able to initiate if you get stunned on the way in. Getting stunned/rooted can prevent you from catching that squishy, completely killing your teams push.
Sunfire Cape
While the DPS it does in teamfights can help, I typically purchase this item based on whether or not I need to do a lot of jungling/farming. This plus defensive ball curl will decimate minions.
Guardian's Angel
Good MR, Great armor, and its passive lets you stay in that team fight beyond where you would normally have to retreat. The more I play Rammus, the earlier I try to build this item.
Randuin's Omen
Powerball in, taunt and they now hit you and are slowed. As they try to run away, trigger the active. Soon powerball is up again as well as tuant. It's almost impossible for somebody to run away from you. However, while the item is beneficial, it isn't super high priority for me. One powerball and taunt should be enough for your team to finish somebody off. It is an easy purchase once you have heart of gold though, which is why it is on this list.
Oracles Elixir
If they have a major stealther on their team you should be the one to purchase this item.
Summary:
Cloth Armor + Pots
Heart of gold + Boots
Giants Belt
Banshee's/Sunfire/Guardian Angel
Randuins
