Elden Ring: Shadow of the Erdtree player finds the perfect way to shut down one of the final boss's most annoying moves, and it's all thanks to best girl Ranni

Elden Ring: Shadow of the Erdtree's final boss is absolutely brutal, but if you're struggling with the fight, fear not, as one player has now discovered a perfect way to counter one of the most annoying moves that can be thrown at you. Be warned, there are spoilers ahead for the final boss.

It took me more hours than I'd like to admit to beat Promised Consort Radahn, but this counter could help speed things up significantly for any magic builds by unlocking the ability to not only dodge but also deal safe damage to the burly foe during his rock throw move, which is otherwise tricky to punish. While it's not too difficult to get away from Radahn as he rips a load of rocks out of the ground and soars into the air, in the process of performing the attack, he tends to get really far away from you. Even if you dodge the boulders as he hurls them, you're probably not going to be able to get to him before he lands to deliver a hit in retaliation before he's onto the next move. 

As demonstrated by Reddit user Popular-List7033, however, using the Ranni's Dark Moon sorcery right after he takes off is an incredibly effective attack. As you can see in the clip below, the magical moon you fire out outright smashes through the incoming boulders, and then hits Radahn for a nice chunk of damage, to boot. This is even better when you consider that Ranni's Dark Moon builds up Frostbite damage, which Radahn is weak to. It also apparently works in phase two, too, as long as you're quick to dodge out of the way of his speedy follow-up attacks right after casting it. 

You can only grab Ranni's Dark Moon once you've gotten a large way through Ranni the Witch's questline, so it now feels like an even greater reward for helping out the action RPG's best girl. Unrelated to the strategy itself, it's also worth noting that Ranni and Radahn are siblings, so it's very appropriate that her power would be able to help you match and even surpass his in this fight. 

Admittedly, unless you're already
