Caustic Resin

Caustic Resin is an essential crafting material. It can be obtained by using a Tier 2 Axe on the Tall Thornwood Tree using RMB in Myrkfen. This is an uncommon drop that decays at a rate of one berry per minute in each stack. Caustic Resin is primarily used with tarberries which will also decay in a similar amount of time. A wise adventurer should be wary of taking too long in the swamp when harvesting this resource.
