[STORY]
Elden Ring takes place in the Lands Between, a fictional landmass ruled over by several demigods. It was previously ruled over by the immortal Queen Marika, who acted as keeper of the Elden Ring, a powerful force that manifested as the physical concept of order. When Marika eventually shattered the Elden Ring and disappeared, her demigod children began warring over pieces of the Ring in an event called the Shattering. Each demigod possesses a shard of the Ring called a Great Rune, which corrupts them with power. In the game, the player character is a Tarnished, one of a group of exiles from the Lands Between who are summoned back after the Shattering. As one of the Tarnished, the player must traverse the realm to repair the Elden Ring and become the Elden Lord.

TUNNEL ADVENTURE

A friend who is also playing Elden Ring was telling me about a cool place to find Smithing Stones so I asked him to show me the spot and got summoned into another world.

The open-world of Elden Ring is so massive it's nice to get advice or tips on where the needed or special stuff is because often if you don't know about it you'll probably ride or run right past it.

We start off by ambushing some mutated-looking miners. Fang slashed away with his Bloodhound Sword and I threw down some electrical support in the form of a Lightning Spear incantation spell. We make for a pretty good combo since he can act as a tank and I can sit back and magic away at enemies from a distance.

This poor guy with the scythe-like pickaxe was dead before he stood up but hadn't registered it yet. Seemed like he was having a tough day so we gave him company for a while.

I keep finding new gear but so far nothing's got the elegant swag of the original Confessor gear. I mean, check out that cape -- my Tarnished so stylish!

I do THREE things wrong here
when we find some new enemies later:

First I locate an enemy and don't call out their location to my friend.

Next I start zapping the monster he already called out earlier.

Due to not keeping track of my FP (magic) bar, I turn around to see my friend getting scorched by the first enemy I spotted and said nothing about ... and can't do anything to immediately help.

And then I try to attack with my sword and not only get pushed back but manage only a measly 18 points of damage haha.

Bloody Finger Invasions always feel like bonus rounds during Co-op Mode. Every time I see the banner announcement I imagine some festive Mario Kart 64 music playing.

We find a shirtless carrying what looks like Tambourines in his hands and he of course goes straight past me to attack my friend, the Host of Fingers, because that's the objective of Bloody Fingers.

But he gets caught in a whirlwind of blade strikes from my friend and I assist with a gift from Olympus, a bolt from Zeus.

The poor guy's already dead but he's dying so slowly my friend just keeps on slashing and slashing away at him.

Magic's flashy but it's pretty cool to watch enemies get diced by the sword machine.

At the end of the tunnels we find a boss door and my friend, as the host, pushes it open to reveal a misty veil.

I start things off with a Lightning Spear straight to the Stonedigger Troll's heart.

Black Flames fireball!

The stonedigger troll's pose in this screenshot made me laugh -- looks like he's scared of something or hurt his leg.
