Wall

Strategy and Synergy
The wall can be built in Hostage zones to block up the shots and give enough time for them to get back up and reward the player. In combat instances, this spell will seldom offer much, aside from being quickly built to be dismantled with for 100 free, since this spell costs no mana at all. This makes the Wall a perfect scapegoat for the aforementioned Salvage spell. This combo along with allows the player to quickly recover 140  for free! That is 10 points lower than, however this synergy can repeat many times during an encounter and will cost only 1 mana (From salvage), allowing for a quick restoration of your shields.
