|+6-30% armor while at low health
Unbreakable is a skill in the crafting skill tree. The skill is in the fourth tier of the skill tree, and requires Industry specialist or Blacksmith at level 5 to level up. Each point allocated to this skill will increase armor by 6% while at low health.
Low health threshold is 25% and lower. It is indicated by your health bar blinking red.
Experience is awarded per craft, not per item crafted (when there are multiple). For example, when you craft wood bridges you will make 2 bridges. Crafting wood bridges doesn't give you 2x the XP because you make 2 bridges.
However, when holding down CTRL to craft multiple 10x at once, you will get 10x the XP as a single craft. The game treats this as 10 separate crafts.
Each crafting skill level increases your armor by 0.5%, for up to 50% at level 100.
