Umbral

Overview
Umbral is the 2nd map that was added (and later reworked in Update Log : 22) to Trenches and it features a bog/swamp like climate with mushroom flora and towering trees with blue leaves being fought over between Noxuia and Rostora.

Unique Mechanics

 * The map features dense flora allowing for excellent ambushes and makes it easier to get behind enemy lines
 * The map features swamps that drastically slow you down upon trying to walk through them
 * Due to the point above, duckboards are used more on this map to act as a bridge to cross the swamps that would otherwise slow you down

Trivia
Umbral might be inspired on a Verdun but it has added jungle vegetation on it.

The map can be possibly turned into a wasteland by using full artillery barrage on both sides.
