Malphite

Malphite is the easiest champion on the roster to understand and one of the most decisive. Unstoppable Force charges across the map and throws everything at the landing point into the air: one well-placed ultimate wins a five versus five on its own, without him needing to do anything else.

Before that, he's a wall. Granite Shield eats the first burst of any trade and recharges the moment he's left alone. Seismic Shard steals movement speed from its target, Ground Slam converts his armor into magic damage. He has no late-game weak window, no difficult mechanic, and one real question every game: when to press the ultimate.

His main appeal is being the game's best answer to anything that attacks fast. Ground Slam cuts enemy attack speed and his natural armor makes any duellist harmless: several toplane matchups become unplayable against him. His shield gives him a very comfortable lane, because it cancels repeated free poke.

On the other hand he has no way to win a fight by himself once the ultimate is spent. His mana suffers early if he uses spells to farm. And since all his weight sits in one button, the enemy team plays around it: an ultimate dropped on a single isolated target, or thrown too early, leaves a Malphite spectating for the twenty seconds that mattered.

Your lane is an exercise in patience. Granite Shield absorbs the first trade, so let it recharge before contesting anything: stepping up without the shield is handing over free health. Max Seismic Shard for the pressure and the slow, which lets you stick to a target or deny a disengage.

Against an opponent who lives off auto attacks, Ground Slam changes everything: the attack speed cut makes a losing duel entirely holdable. Watch your mana, that's your real early constraint. And once your ultimate is up, the lane becomes secondary: your presence on other lanes is worth more than three waves of minions.

The first spike is sharp and singular: your ultimate. Before it you're a wall that absorbs. After it you're a threat that can open any fight on the map. Your entire game organises around its availability.

After that, armor is your real damage item, since Ground Slam scales off it directly. Stacking defence isn't a passive choice on this champion, it's an offensive one. The last spike is cooldown reduction: a Malphite who gets his ultimate back twice in a teamfight completely changes the rhythm of a late game.

All your value sits in choosing the moment. Wait for the enemy to group, and above all wait for your team to be ready to follow: a perfect ultimate on three targets means nothing if nobody comes with you. Look for corridors and tight spaces where the enemy can't spread out.

Once you're in, you're not the main character any more. Stick to the most dangerous target, slow it, cut its attack speed, and let your team do the work. Your death isn't a problem if the fight is won: you're the first piece the plan spends, not the one that has to survive.
