Not Updated For Current Season
Here is my new Rammus Version i'v been playing for the last couple days , and it actually work perfectly.
Note that Shurelya's Firecrest is not in the list of item choice, But this items should be your priority.
Also good thing about rammus is that you can always go back in Lane super quickly with ur Powerball , So dont hesitate to return to base to buy stuff. Like boots, and Philosopher Stone at lvl 3-4. These items ll give you a edge over your enemies
Also i love to take ignite and Slow. These 2 spells allow you to neutralize a Single enemy by yourself really quickly.
PowerBall, Taunt, Exhaust, Randuin's Omens, Shurelya's Firecrest. Allow you to Chase like hell and never let a enemies get out of your claw. Also with the extra cooldown you get from , Firecrest and the mana runes , this also help you to be everywhere needed by your team. You can always change Lane super quickly.
Here is a Exemple of final items build also as the order im buying it
