The Chosen Ones

Some minor bugs in chpt 7:

a) Potion of mana has no effect on Fradz (suppose to have +50 permanent mana)

b) Description of restoration scroll. 700% of the health and mana?

c) After one's has the other 2 pieces of holgro, if you choose the third option when talk to paladin (holgro optional quest), you will no longer able to select your heroes.
