I have a question...I know with Skull Mage if you put him in bastion reserve defense that his fortitude skill works and after he inevitably dies he latches onto defense structures, but I was wondering if putting Won TON in bastion defense would trigger his fortitude skill?? Or putting Arcane caster would trigger hers (i.e. instantly increasing defensive structure dmg by 10%)?  I assume Wolf in bastion increases walls defense when he comes out??  Thank you!!

Ok, thanks man.  I didn't know if anybody had a definitive answer.  Guess I'll have to do some more testing.

We have tested a lot and found no base structure bonus from fortitude (dr, pg, wt, etc) work while in reserve. Most hero fortitude bonuses, like ambro, work in reserve.
