You can break a class by making it overpowered while still not being god tier

[NinjaTaru72]

Sch - shields from heals now shield for 3x the amount healed, and have light spikes effect.
Aether flow gives stack of 5 and restores half of your max mp when cast.
Ss and shadow flare can coexist.
Ss no longer takes aether flow stack.
Adloquium costs the same as cure
Lustrate uses 10% of your max mana rather than aether flow stack
Shields from heals last till full damage is taken, rather than 30 seconds. (would love this)
