I don't know, majestic arrow eater looks like a one shot for me. unless two like that, i'd need another cauldron.
There are usually five like that... So many arrow eaters in UD and so many sources of majestic in ST.
UD is dependent on 3 early game spells, without these spells UD is the most trash faction of all time. It's a sad dependence. UD will always be hated whenever it's even kind of good.
