Jumping up and down waving my arms.  I got BANNED when I posted this.  I still need help.  

This isn't your full roster. Would have been more useful to start the thread with that. I'm using the one you posted here: https://plarium.com/forum/en/raid-shadow-legends/674_game-discussion/615875_arena---dragon/

Spider:

• Scyl (CC on Spiderlings, healing) - make her fast, doesn't need to be as fast as Apoth though. 180-200 SPD should be fine Relentless / Stun sets are useful for her. give her 190-220 ACC. other stats are irrelevant. 
• Psylar (TM control) - make her fast. again, doesn't need to be as fast as Apoth, but probably faster than Scyl. give her 190-220 acc. other stats are irrelevant.
• Coldheart (damage, TM control) - make iher reasonably fast. around same speed as scyl. 70% CR, and as much CDMG as possible. try for 190-220 ACC, but if you have to, you can afford to lose some here.
• Apoth (speed up, TM up, healing) - make him *fast* - 200+, ideally 250+ SPD. other stats are irrelevant.
• Mountain King (damage absorption) - make sure he has 300 RES, and otherwise, just stack HP on him. He needs no speed at all - his only purpose is to be attacked by the spiderlings.

IG - just use your Dragon 20 team. No need to change anything. If you're running any Force champs, you may want to swap them out, but its not really that important. You could run Eva here if you want, for block revive.

FK - i thought we had another thread on this one already? did the teams in that thread not work?

We built a FK team for 20 but I could not get past 19.  

I am going to upgrade something to lvl 6 for the CvC points.  I hoped something in the pic might have dungeon value alos.  

Okay - so 19 is Magic, so I'd probably do something like:

• Psylar (TM control)
• Coldheart (TM control, multi-hit on boss) - turn off a3 on wave two, a1 opener on boss
• Duchess (protection)
• Draco (wave debuffing, multi-hit a2 on boss) - turn off a2 on wave two, a2 opener on boss
• Kreela (wave clearing) - not convinced about running her, but i don't see a better wave clearing champ in your roster

Which aura?

How do I turn off A2 and A1 for the champs on wave 2?

Probably Duchess - I haven't checked but I think she's the only one with a speed aura that works in dungeons. Regarding turning off stuff - you open the saved team, and edit the AI settings.

Duchess aura. 

Go to the team setup page when you pick the dungeon stage, then go to Round 2 and make adjustments as you'd like. :)
