An interesting build was made in our group. Basically the night took the stalwart ability combined with the mace of kelos and mana weave. This meant that anytime he was killed he could move and attack and if he rolled a surge then recovered one health. If he did not roll a surge then he could use the mana weave to gain a surge and recover one health. This made him near invincible since it was rare that he did not roll at least one surge to begin with. There was actually a moment of debate as to whether this was allowable or if he was required to be knocked out after the attack. We decided this was allowable and I think partly because it was just a cool build.
Another question that was brought up was if the iron ring allowed you to add a shield for a blank die roll even if you rerolled that die after getting the blank or if the blank had to be the final result. Just curious how others are playing it.
