Hi Guys!
I will not write down the whole reinforcements rule in connection with this one just a part of it, it can be found in Labirinth of Ruin Rulebook page 36.
The following is stated:
...............................
"The Overlord must pay a number of damage tokens equal to the number of spaces the reinforced monster occupies. For example, an arachyura occupies 4 spaces and would cost 4 damage tokens to reinforce. The Overlord may reinforce up to 2 monsters."
"Ariad may be reinforced on Exit at the cost of 3 damage tokens."
So question: Ariad is included or excluded, the following phrase -The Overlord may reinforce up to 2 monsters-
So Ariad is 1 monster and i can put an other 1 from my open group to the map -as the Reinforcement RAW-?
