this may seem like a dumb question, but with the librarian power veil of time, are you allowed to reroll all rolls (ie i could reroll an inv. save and a missed shot in the same turn) or is it just all rolls of one type (ie i could reroll 2 failed inv. saves or 2 missed shots, but not a combination).
oh, and a second point. if i wanted to combine fury of the ancients and veil of time (on an epistolary librarian), i can do so for (9+10) 19 points or i can do it for (30+3) 33 points. or does upgrading the first power to a new power cost the epistolary cost, ie the same amount as buying a new power?
this may well have come up before, but i've searched and not found it, so forgive me
