So tonight we're playing the "Death's Wing" or something like that adventure and I get 1 open group of monsters ... its a 3 person game ... I thought I'd try giants ... seem like fun but with 3 people I only get 1... So i'm thinking maybe this isn't the best choice ... and maybe I should try something else like Sorcerors ...

ANyway my question is ... if the unit size is 1(red) monster and the reinforcements is in effect... if that monster dies ... can I bring it back? (Because the open monter unit is gone ... I'm not sure if you can reinforce or not)

Yes, you can keep bringing it back.

Thanks I may use something else but its good to know for future reference

Reinforcements are determined by encounter so always check what is allowed. There is no set in stone rule for what can be reinforced.

Yes- and I believe your question was anchored in group limits. That limitation (in the case of Giants, 1 master and 0 minions for a 3 hero game) determines the maximum number of figures that can be ON THE MAP. If your master dies and you have the opportunity to place a giant, you can place one so long as you dont end up with more than the group limit on the map at a time.

What if a Master Troll is killed and replaced by a Minion Troll? If the Group Limit is (1 Master/0 Minion), can the Master reinforcement be placed if the Minion Troll is still alive and bashing?

See my response in your other topic. Because your minion troll was placed with "Undying" and that ability specifically says that the placed minion ignores group limits, you may still place a master even if that minion is still on the map. In other words, that minion is not a "placeholder" for the master- it is technically an entirely separate monster, and not considered for reinforcements.
