Flame Wall is an AoE fire spell skill that creates a wall of fire at the cursor location, igniting enemies standing in them. Any projectile fired by allied entities that pass through this wall will gain added fire damage. If you have a Lightning Infusion, it is consumed to add additional lightning damage to projectiles that pass through it.

Skill functions and interactions

Projectiles that are fired by the player and their allies passing through Flame Wall deal added fire damage. If a Lightning Infusion is consumed upon casting, it will also deal added lightning damage. Flame Wall is limited to 3 instances at a time. Attempting to place a Flame Wall while there are 3 other Flame Walls down results in the de-spawning of the oldest one created.

Item	Description

Version history

Version	Changes
0.3.0	Flame Wall: Can now consume a Lightning Infusion to grant additional Lightning Damage to projectiles that pass through it, as well as the Fire Damage. No longer causes projectiles that pass through it to ignite enemies. Now deals 1.8 to 59.6 Fire Damage per second to enemies in the wall at Gem levels 1-20. Now ignites as though dealing 5-8 Fire Damage at gem level 1 (previously 9 to 14), scaling up to 181-271 at gem level 20 (previously 299-448). Now has a base Critical Hit chance of 5% (previously 0%).
0.2.1	Added "Barrageable" gem tag.[Undocumented]
0.2.0	Many Skills have had their base damage and/or damage growth per level rebalanced. Most of these changes are not specifically mentioned below as the changes are too widespread. Flame Wall now causes projectiles which pass through the wall to deal 33 to 48 Added Fire Damage at gem level 20 (previously 64 to 91), while the Gem level 1 values are unchanged. More significant reductions have been made past Gem level 20.
0.1.0	Introduced to the game.
