- Terra Alloy - Provides a flat boost to maximum HP
- Auto Heal - Periodically heals the unit
- Healing Amplifier - Increase the effect of healing
Rarity and drop requirements Edit
- Requirement 1: The game generates random number between 0 and 1. If the value is smaller than 0.00035 then proceed to Requirement 2.
- Requirement 2: Highest Level achieved > 3 (i.e. drops only if you've beaten Kenta Phi - doesn't mean it can't drop on Section IV (!) )
If all 2 of the above are achieved, the killed unit drops Defensive Wall.
Maximal amount of Defensive Wall that you can have (field + inventory): 10
/Taken directly from the game code./
- Defensive Walls in the mobile version of the game are longer than their Flash counterparts.
