Abbatial
Rather amusingly, adjectives in Scribblenauts can sometimes have no discernible effect, and indeed, that is fairly true to life. If you were to point at a person and describe them as being necessary, without them actually putting this into action, it’s really up for interpretation whether they are in fact necessary or not – and even if they do something that in your eyes is entirely necessary, in actuality, it’s fairly subjective. Adjectives are fun like that.
In the case of abbatial, it adds a halo to whatever noun it is assigned to. When speaking in the literal sense, abbatial is relating to an abbey, abbot or abbess, which makes its context in the game rather fitting. This is primarily an aesthetic alteration, however, and will not wildly alter the behavior of the target beyond giving it a fascination with religious items like a toddler collecting their favorite toys. If you’re after something a little more interactive (but not nearly as lyrically compelling), try making it ‘angelic’, wherein it will also sprout wings. Angelic beings may be benevolent, but if you commit an atrocity on an innocent, they can and will go to town on your wicked ass. Most damnable!
