Hello,
I am not yet a gamer of arena rex, I intend to buy the minis during the gencon, but my arena is ready : I ordered a custom mat by deepcut studio, and made some hazards.
The hazards :
The columns are simple hazards, the one with pikes and the mantrap are some wounding hazards and the pit and the blaze are lethal hazards.
I confess myself inspired by the works of Gomez.
Here is the "arena" mat with hazards :
I wish some marklings to place the hazards symetricaly. I asked deepcut studio that these marklings look like lines on playground. I think they also could be useful for scenarios.
Sorry for my english : I'm a french player and it seems that we are not good at languages...
