this helps thanks so much . So if I understand it correctly:
- Top floor: 2/2, i.e. 2 x pools of 2 resolve - spend 4 get 4 back split 2/2 ie cost free to place with free steel thrown in
- Middle floor: 2/1, i.e. 1 x pool of 2 resolve and 1 x pool of 1 resolve - spend 4 resolve get 3 back split 1 pool 2 1 pool 1 ie effectively cost 1 resolve with a steel thrown in
- Ground floor: 1/1, i.e. 2 x pools of 1 resolve - spend 4 get 2 back split 2x 1 pool ie costs 2 resolve with a steel thrown in
