1) There are only 4 melee training tokens. Does this limit the heroes to only four melee
purchases in a game? For example, lets say three heroes play melee characters. Two of the
heroes buy 2 melee training tokens each (so four have been purchased). Thus the third
melee hero would not be able to purchase a melee training token since the shop is out of
the melee training tokens.

2) The only use for an OL rolling surges is for collecting threat (2 surge = 1 threat token
if not a miss). There are no other options, correct?

1) Yes

2) Normally yes. However if you own AoD and have Dark Priests, then they convert 1 surge into 1 Threat, and get 1 damage +1 range for each surge.

From what I remember, everything in the game is explicitly limited by the number of tokens available in the set. So if the heroes posses 9 life potions, then they can no longer purchase any, nor will any appear in the dungeon until they use some. Along those lines, I believe the same goes for money and overlord threat (which I think caps at 68?).

Surges also do special things for Trolls (AoD), due to the Bash ability, and if the heroes get the Fear ability (there's a gold treasure that grants it) then monsters can of course spend surges to overcome the Fear.

However, except when there's an effect that specifically allows surges to be spent on something else, the only use for the surges monsters roll is 2 surges -> 1 threat (and that option is only available if you hit a hero).

That's right, I forgot about Bash. Thanks for throwing that in there.
