Talk about Death spells, how your death character is doing, death combos, And good Secoundary combos with Death.
Some good combos are
Death Shield + Sacrifice
With no boosts you take 50 damage to heal anyone 700 health.
There is also a glitch were you can heal YOURSELF!!!!!! with sacrifice!
Doom and Gloom + Lifestealing
Lifestealing spells are unaffected by Doom and Gloom so your healing is unaffected while all your opponents have their healing crippled.
BAD COMBOS
Sacrifice + Deathblade
Deathblade will increase the damage you take from Sacrifice.
Doom and Gloom + Sacrifice You will halve the damage you heal but do nothing to the damage you take!
