It's a simple tanky build, but with Rammus' high base defenses, you can be the DEFINITION of tanky. By the time you finish every item, you will have at least 300 armor and magic resist. Plus with cinderhulk's 15% HP gain, you can have 5000 health! Beware though, because you're nothing offensively, making you a bodyguard or peeler instead of bruiser. Also, without offensive items, you can be shut down early, disabling the superior durability end-game. I'd say it's really fun to shrug off the damage of the enemy team and being the epic-front-line Mecha Sonic!
