Realm has lagged out due to lightning summon command block

Hi Mcvncontact, I hope you're doing great out there despite the issue that you're experiencing. I am an Independent advisor and I am here to help you in regard to your concern.

Kindly repair the game by following the steps below:

Windows Settings > Apps & Features > Apps > Search for the game > Advanced Options > Repair.

Also, I would appreciate it if you can let me know what exactly happen whenever your friends try to join your realm?

I generally roll with the lightning ring with these two because their lightning butt slams deal some serious damage and the AOE if pretty big if you don't get out of the way in time.. also good to have a shield with high stability, and armor with lightning
resist. Summon Solaire and other phantoms for assistance (there are usually quite a few summon signs at the bonfire before these 2).

I have noticed a lack of summon signs as I have increased my level, sucks because it gets harder especially in NG+! But yea summon Solaire, hit them with fire, and boost your lightning defense for when you smite one of them the other starts using lightning.

To clarify on the co-op.

If your human, you can summon others to play with you.

When your undead you can't summon others into your realm but you can be summoned. (Leave a white soap marker)
