Eternal Hell
“The blaze consumes both sinner and saint”.
This mod adds a very simple infernal flame but with an interesting (and extremely difficult to survive) effect: for each hero in the formation, both heroes and enemies will receive permanent burn dots, stacking indefinitely.
There are two variations: the first adds the dots at the start of each round, while the second adds a dot at the start of each hero’s turn.
Apart from that, the flame does not include extra light or stats modifiers, it’s like playing without a flame (ignoring the eternal fire that will consume your heroes, of course).
