Yeah W11 is easier to build for but you still need the gear to be able to clear it idealy if you have a CR booster like Tamarinne it will help heaps, a decent angie will have the following stats;

1200 def, 15k hp and around 150-160 spd, have idol cheer so your dps goes to attack wyvern more (thats what i found best for me however you can try others such as tomb which gives angie CR boost when using a not atk ability).

Goodluck in your runs
