The goal of this Cerb build is to be In-and-Out support. You run in, blast all your abilities, hop out, and repeat. The super-long cooldowns are practically nothing, with that almost 100-sec ult cooldown going to 30 seconds or less.
I play as a defensive meat shield, knocking up enemies and distracting them so my allies get their hits in safely.
Build shoes first for some good starting cooldown reduction. Pridwen next for a bit of def and more cooldown, plus its passive helps protect you after you ult and everyone who didn't die targets you. The next three are to increase the damage you do with your attacks, which helps you pack a punch late game. The blade is there in case you hit a healer, but it can be swapped for whatever you prefer. I keep it for the added attack and movement speed anyways.
Shoes of Focus
PASSIVE - When your Ultimate ability has finished casting, you gain a Shield equal to 90% of your Protections from items and abilities for 5s. When destroyed, by timing out or being depleted, it explodes in a 30 unit radius and deals Magical damage equal to 75% of your Protections from items and abilities and slows targets by 25% for 3s. This can only occur once every 45 seconds.
AURA - Allied gods within 70 units have their Magical Lifesteal increased by 8% and their Magical Power increased by 20 or their Physical Lifesteal increased by 6% and their Physical Power increased by 15.
AURA - Enemy gods within 55 units have their Magical Protection reduced by 10%.
PASSIVE - Killing or assisting an enemy minion provides you with 1 stack, granting 1% Movement Speed and 4 Magical Power per stack. Stacks last for 15s and stack up to 5 times. Enemy gods provide 5 stacks.
Belt solidifies you as a support, by helping buff your allies. In a pinch, however, you can use them alone to rack up some massive damage during a blitz. Shield of thorns is my go-to relic when I'm surrounded and has saved me more times than i can count. Don't be afraid to run purification beads if you are worried about stuns!
Most squishies are very vulnerable to this, and anyone who relies on strictly melee rarely gets hits in if you pounce fast enough.
Anyone who can slow or stun you! Stunning is my #1 cause of death as cerb, so beware. Run beads if you don't think you can outrun them.
