Viper’s Marsh Guide
The key to this entire adventure is the damage bonus from faction advantages.
This is because at the start you’re given a relic called the “Flag of Courage“. This unique relic buffs your heroes damage by 100% and reduces their damage taken by 25% when they have a factional advantage.
Some of the enemies guarding the crystal treasure chests are actually very strong, so you might have to create a faction specific team for each one.
There’s 4 different crystal treasure chests in this adventure, 3 of them are surrounding a lake in the middle of the map. The 4th one is in the north west and it contains the Dura’s Blade artifact.
Mixed Chief Enemies (North West)
This is the enemy that guards the crystal chest which contains the Dura’s Blade artifact. It’s located North West of the start.
This is actually a pretty easy fight and the easiest out of all the chief enemies on the map. If you just want the artifact it might be a good idea to just go straight for it.
