At each level

4% increased Physical Armor per level

Level 1
Physical Armor points from equipped items are increased by 4%.
Level 2
Physical Armor points from equipped items are increased by 8%.
Level 3
Physical Armor points from equipped items are increased by 12%.

Each level costs 1 skill point: 1, 2, 3 in total. Rule from the Enshrouded dedicated server's code (build 25988414, which matches the game's changelist 1269579).

Cheapest way there

2 skill points from the nearest Spark, taking one level of each node on the way:

  1. Constitution Attribute, 1 pt
  2. Heavy Plates Passive skill, 1 pt

A node opens when a link joins it to a Spark or to a node you have, whichever way the link points, and each level costs the node's points: the unlock check in the Enshrouded dedicated server's code (build 25988414, which matches the game's changelist 1269579). From level points alone (2 a level) that's character level 2; extra skill points from the world bring it lower.
