|Level 2:|| Increased Armor|
Increased Health Recovery
|Level 3:||Further Increased Armor|
The Tank's passive skill. At level 2, the skill increases his total health and increase health regeneration. At level 3, the skill increases his total health once again.
A Level 3 passive Tank cannot be killed by an Assassins grapple attack, use this to your advantage.
If you're planning on playing on offense it's a good idea to upgrade this first, so you can take more damage without dying. If you're planning on playing defense though, it's better to give preference to Tank Deploy instead.
