BTW everyone i listed on my current team is fully booked. I also fully booked dhukk the pierced and have tried subbing him in there with  miscreated d monster who i do not have booked yet. Those are the only 7 I have really tried spider with and have not been able to find the right combination yet. Please help!

you should definitely try to get your gear to level 16; not for spider specifically, but just in general.

in terms of spider specifically, you should run both coldheart and miscreated monster. mm offers a huge shielf buff and coldheart has massive damage and a substantial turn meter decrease on her A3. You'll also get a huge amount of value out of drexthar and scyll if/when you get them. scyll offers consistant tm decrease and revival, while drexthar has hp burn (the most valueable debuff against spider) and will act as an off-affinity tank against level 20.

i read somewhere that the rmiger has been  nerfed and is now useless in spider , is that correct?

From everything I read ,, you need to get / Find / have an AOE HP Burn Hero .... or two ? 

and Debuff stripper / Healer / rezer

Nope. If you heard that, it was probably in relation to the planed lvl 25 dungeons where Armiger will be less useful in Spider because he will have a weak affinity against Spider 25. 

Armiger himself remains a FTP god as he should be

Your  not  using  speed  boots  are  you...
