An ally takes 16% less damage when they receive a single target dual attack/counterattack/additional attack, and before the attack is made, said ally without a barrier will be granted a Barrier, equal to 12% own max health if their health is higher than 99% or 6% if their health is lower than 99%, lasting for 1 round, then heals all allies equal to 8% own max health and advance all allies action bar by 5%. When the first effect is triggered for the 1st time and every 4th time thereafter, additionally use [Holy Alliance Summons].
