drop shazzar and adelyn and put in achack and warmaiden. Warmaiden needs to be faster than both coldhearts.

Thank you for your reply, I tried that lineup, and Warmaiden went down way too fast, she is only 50 so I expected that, but I still can't get it down, I am not seeing any benefit with the two Coldhearts, even tried it with my level 50 Armiger

take scren shots of the champions and post them. This is a gearing issue as a single coldheart well equipped would kill spider 13.

Im going to fuess you are missing speed+accuracy.

Are all your champions over 170 speed? Do they have 130+ accuracy. Do the coldhearts have 70% crit rate?

Thank you, that's the problem, I need better gear/enchants

You may need to run Dragon more, Spider is a bit odd. Once you have a team down, Spider is the easiest of the 4 Dungeon Bosses (5 if you count Odin). 

Honestly you might do well with Achak and Neldor, I think Achak will freeze the spiderlings. Perception Gear is gonna be the best option if you can craft it rank 4-5 or preferrably 5-6.

With 2 Coldhearts, and decrease speed, you can probably keep Spider from ever getting a turn. What is likely killing you are the spiderlings. That's where Neldor and Achak come into play, getting freezes out to lock them down (especially with Neldor and Achak's passive boosting the TM of your whole team).

Warmaiden, like Evilzed said, is gonna be needed for the Decrease Defense unless you have another champ that can do Decrease Defense 60% (single target is fine). 

Coldheart, Coldheart, Warmaiden, Achak, Neldor. Try that one time and see if enough freezes stay out and focus all your DPS on the Spider Boss. Don't use Coldheart's A2.

What is a sub for royal guard , I keep seeing every spider build with him. I have 5 CH and not 1 guard lol. Gonna work on 3 CH, I've been told thatll work but what's the role of guard that i can swap out? https://omegle.onl/   

There is none. 3CH will work just fine.

# CH should make short work of SP 13....
