Personally, I'd rather see a slight buff to Deer Knight. Ever since the buff to Scarecrow, there is almost no point to use Deer Knight since with Epic enhancements, Scarecrow deals almost double the damage Deer Knight does and it steals hp. For my set up, I keep 1 Deer Knight just in case I need to deal a little damage or get a DoT on the enemy. Otherwise, I just use Lulu or Scarecrow.
There actually is a 4 pip multi hit Death spell called Ship of Fools: www.wizard101central.com/wiki/Spell:Ship_of_Fools#axzz6ZltMBH73. However, it's in the Celestial Spellemental Pack and it requires Spellements. I gave up on trying to get it after awhile since there are 3 other spellements you can get in the pack. Hopefully, they have an update making certain spellements easier to get but for now, I'd just focus on using Scarecrow past level 48 till 130.
well there's the new celestial pack that has ship of fools which is probably what you're looking for probably not the answer you seek since it entails opening a pack for spellements, but it's either that or deer knight.
Well there is the new spell called Ship of Fools, It's Death worth 4 pips. You can only get the spell through Spellements from the Celestian Spellement pack. It's a decent spell it's an aoe and a health absorb too.
Ship of Fools exists, Colossafrog exists as well on the Gloomy Eye.
Colossafrog also exists as a treasure card. I think we are fine with Deer Knight, Scarecrow and Ship of Fools. At max, you start with 5 allowing that first round Deer. Death also has an easier time of getting through the game than the other schools in my opinion. So keeping things the way they are is just fine.
