Here is an OP build for rammus, i used it alot. and it totally makes you own!

Ravaged by Rune Wars long past, the lands south of the Great Barrier are wrecked by chaotic magical storms, leaving the grasp of nature's rule tenuous at best. While abnormal flora or fauna are the norm rather than the exception in these ruined areas, perhaps none is more curious than the case of Rammus. While no one is entirely certain why an armadillo from the Shurima Desert crossed the ***ungu Jungle into the Plague Jungles, Rammus made just such a journey. There, amongst the twisted vines and festering rot, he came across an oddity - a healthy evergreen hedge maze, stretching as far as the eye could see. As he explored the maze, something compelled him toward its center - a light, a presence of some kind. As he drew closer, the light surged, blinding him and knocking him unconscious.

When he awoke, Rammus' whole world had changed. The maze had vanished and he felt truly cognizant for the first time in his otherwise unremarkable life. As his predicament dawned on him, Rammus had a moment of panic. As he trembled, the earth around him began to shake, the intensity increasing until he managed to steady himself. As the quake receded, Rammus arose and left the Plague Jungles in search of others like him. His search brought him across all the lands south of the Great Barrier, but everywhere he went, he was unique.The hardships of this sojourn inspired him to craft the suit of armor that would earn him the title of Armordillo. Rammus' quest eventually drew him to the only place where a sentient armadillo is less than confounding - the League of Legends.

''I've seen a lot of things, but this... this is a first.'' - Ezreal, the Prodigal Explorer, after first meeting Rammus

Spiked Shell
Rammus gains additional damage as his shell becomes reinforced, converting 25% of his armor into damage.

This passive gives Rammus viable attack damage. He will never be Master Yi, but his physical attacks will be noticeable enough that the enemy can't simply ignore them. It does exactly what the tooltip says.


Doran's Shield = +2 damage

Cloth Armor = +4.5 damage

Ninja Tabi = +6.25 damage

Heart of Gold = +6.75 damage

Aegis of the Legion = +7.5 damage

Guardian Angel = +17 damage

Thornmail = +25 damage

Easiest way to think of it: +20 armor = +5 damage


Powerball
Rammus accelerates in a ball towards his enemies, dealing 100/150/200/250/300 (+1) magic damage and causing 20/25/30/35/40% reduced movement speed to nearby enemies on impact.

Cost - 70/80/90/100/110 Mana

** Hits all enemies in a 300 AoE.**
**Right clicking or A-clicking an enemy will not cause you to ram into them. Instead, you will stop just short of their model, in the position to autoattack. To ensure a hit, click a spot next to or behind them.**
** In order to hit Golem, Dragon, or a big Cho'Gath, you must collide with the back of their hitbox.**
** Powerball continues through Flash : this can surprise enemies
** Can be canceled at any time by pressing Q again.**


Defensive Ball Curl
Rammus goes into a defensive formation for 6 seconds, increasing his armor and magic resistance by 40/60/80/100/120 and returning 15/25/35/45/55[(+0.10)*(armor)] magic damage to attackers.
Cooldown - 14/14/14/14/14 seconds
Cost - 40/40/40/40/40 Mana

**Can be canceled at any time by tapping W again.**
**Damage return procs spell vamp (courtesy Civil Enemy).**
**Does not proc on Sivir's Ricochetor incoming Thornmail damage


Puncturing Taunt
Rammus taunts the unit into a reckless assault, reducing their armor by 10/15/20/25/30 and forcing them to attack Rammus for 1/1.5/2/2.5/3 second(s).
Cooldown - 12/12/12/12/12 seconds
Cost - 50/60/70/80/90 Mana
Range - 325

** Sometimes bugs a bit if at maximum 325 range. To ensure target switch get closer to enemy.**
** Remember enemy doesn't hit you immediately when you taunt. There is a brief time before they attack as they switch targets and move over to you or their attack cooldown timer ticks (this is important for tower aggro).**
**Cleansable.**
**Switches target of all minions except Baron.**


Tremors
Rammus creates tremors beneath him, dealing 65/130/195 (+0.3) magic damage per second to nearby units and structures.
Lasts 8 seconds.
Cooldown - 60 seconds
Cost - 120/120/120 Mana
Range - 300

**The damage is entirely independent of the animation, it will strike once per second (regardless of the apparent pulses) and a little bit beyond the range of the animation.**
**Continues during Powerballuse.**
**The AoE hits through thin walls.**


explanation taken from Bguggs's Guide to the Competitive Rammus

aaah u use noob runes most will say.. well, then pick ur own runes what u think is good, i allway's use this. and it works fine for me, u remember the 25% of armor goes into atk dmg? well, i make alot of kills because when i taunt i deal alot of dmg too. sure it might not be the best runes, but it works great for me!

i think i don't have to explain alot here, just get some more def, and some mana because ur allway's low on that

we start off with a Dorans Shield[*]then we get a Ninja Tabi[*]or a Mercury's Treads[*] depens, if there are more then 2 stunnes/slowers in the enemy team u need the Mercury's Treads[*]otherwise allway's go for the Ninja Tabi[*]boosts ur everything at the beginning. After ur boots u need to get the Aegis of the Legion[*]why? because it's the best item u can get! boosts ur team, and ur own ALOT! after that we go for the Warmog's Armor[*]u already have some nice armor and mres, so this little hp lets u take around 2000 more dmg! because of the armor ur Health is worth alot more! after the Warmog's Armor[*] u are a good tank already. Then u need the get the Thornmail[*]or the Force of Nature[*]wich item u get first depens on ur enemy team, just look what they have more, atk dmg or ability power? pretty easy i guess..after this u can take another Warmog's Armor[*]or wich one i prefer a Gaurdian Angel[*]

Why u do this skills? i start with ur Qjust because ur early at ur lane, and i can go Base and back in no time. after this i get my E skill, just because if they are very agressive u can pull em in ur tower and thier done.. be sure to lvl ur Eskill any time possible, but first on lvl 3 get ur Wskill, boosts ur armor (so also ur atk dmg) and let the enemy take dmg when he atks u, after that just keep doing like this, lvl ur Ulti (R) when ever possible, and also ur E skill, then ur Wskill, the last priority is ur Qskill.




ill explain u how to use ur skills, if he's near you, use ur Eskill, then ur Wskill, then ur Rskill. u will do really sick dmg! once ur taunt has gone, hit him with ur Q skill, it slows him and u have enough time to kill him.

when he's furter away, use ur Qskill then Ethen Wthen R

ahh noob heal!!..well NO it's not, it saves ur *** alot, also ur team mates. and think about this, normally it's just a low heal, now it is still but because of ur amount of armor and mres, it is worth alot more, lets say it heals u for 300HP, u got 70% dmg reduction. so u can get alot dmg befor ur death! so Heal then escape with ur Q skill! Why flash ? it's the best spell ever for Rammus.. u go with ur Q, there are some minions between u and ur target, just flash and u hit him instand with ur Q skill, then E then W then R. and he's death

I didn't make this build to look nice, but to help people playing rammus, if you don't believe this build is good, then try it.

because mobafire made it expire, but nothing has changed on here. i just putted it back
