The  team  that  i  use  for  all  Scarabs  (this  worked  on  Hard  as  well,  level  30,  but  havent  tested  further)

High  Khatun-  Lead  ---  Turn  Meter,  Decrease  Speed,  Increase  Speed

Miscreated  Monster  ---  Shields  (NEEDS  BOOKS)

Armiger  ---  Turn  Meter  (Destroy  Set)

Armiger  ---  Turn  Meter

Alure  ---  Turn  Meter

Make  sure  MM's  A2  is  up  when  you  enter  the  fight.  He  also  needs  to  be  the  fastest.  You  should  have  enough  control  for  the  waves.  You  could  probably  swap  in  the  two  Coldhearts  for  the  two  Armigers,  as  long  as  someone  is  in  Destroy  gear.

What Destroyer said should work. Alternatively, if you have a bunch of champions with decent resistance, you can go for a team that doesn't reduce TM as much and just takes the hits, with Brogni in lead for his aura, so that plus their resistance stats prevents most of the debuffs (on Hard stage 30, they needed about 250 plus the aura - on Normal 100, 200 plus aura should be enough). Brogni's shield can't be removed, though it can be destroyed if you take enough hits. 

I see you have Brogni. Have you got him booked yet? I believe he should be able to keep his shield up constantly when fully booked, especially with his A2 boosting the shield?

This strategy will work through 100 hard, with at least 1 armiger in destroy gear.   The speed and accuracy requirements are ridiculous high at 100.  I run:

MM (250)

Apo (HK is better) @245

Stag (Destroy)

Armiger (Destroy)

Alure

The AI is bad for Armiger and Alure, so if you are too fast they start using a2/a3 .... so need to manual.  Also if MM has lasting gifts it is slightly problematic.

No, you can't get perfect uptime on Brogni's shield even when booked. So you either need a second shielding champ like MM, or you just accept that some hits will be made without a shield up and build the team tough enough to survive the counterattacks that will result. 

Ah you're right, forgot the A2 only boosts the value of the shield, not the duration.

In that case, I would think the simplest solution for him would just be to get another champ with a shield buff, so that he can time it to use his Brogni A2 to boost the other champ's shield (if it's not strong enough on its own).

Thanks all!

Yes,  I  have  been  experiencing  many  technical  difficulties with  that  team  due  to  my  lasting  gifts  and  cycle  of  magic  masteries.  It's  all  because  of  that  stupid  Shield  change...  and  wasn't  it  just  better  for  like  two  champions-  Scrapper  and  Madame  Serris?
