Divine Might (Enchantment)
For now it's not worth much. Whirling Spirit and Gray Wraith are only Incorporal monster for now
Mana Prism (Conjuration)
Again not worth to put in spellbook, very situational spell. Good only against mana control Wizard
I expect Divine Might to become more important as more incorporeal creatures are added to the game. Whirling Spirit, Gray Wraith, and Invisible Stalker are still quite difficult to kill without ethereal attacks though.
I have removed Mana Prism. I originally included it because I mistakenly thought it worked on removal costs for condition markers.
@Kharhaz I am on the fence about including Retaliate on this list. I need to use more Retaliate in more spellbooks before I can make that decision. Surging Wave is a good suggestion though. Didn't think about that. It is cheap, ranges 0-2, unavoidable, puts out burn conditions, and has ~83% chance of Slam. The only thing I dislike about it is that it can't target flyers.
Retaliate is a really strong card, especially since the Battle Fury errata.
Its good because its not a mandatory reveal (so you can actually choose when you get your second attack)
And, like Battle Fury used to be ruled, its a new attack and not an "additional strike".. so you get full damage from melee+X, Vampirism, and other buffs. With good timing, you can reveal it the same round as you Battle Fury and can squeeze a third attack out of yourself or a creature (assuming you or that creature is being attacked.)
Surging Wave's high Slam chance is reliable enough that I usually run it instead of Knockdown in most cases.
Jet Stream is also a strong contender as a generally useful card, very high Push chance plus damageā¦ if you are pushing a target through a passage attack walls you don't have to pay extra mana for the effect like you would with Push, Bash or Wave. So in that case its not only cheaper but you also get the Jet Stream Damage on top of the Wall damage. (Plus its etherial and gets even more damage against Flying targets. )
The problem with Divine Might is that, by the same reasoning that they will add more incorporeal objects.. they will also continue to add Etherial attack spells and creatures with Etherial attacks, or weapons that do Etherial damage, all of which makes the card unneeded in most cases. I generally have enough Etherial damage on hand passively just from Attack spells/weapon choice/creatures already present in the spell book.
