Nasty tricks with Nemelex! Who said destruction decks are the only ones having offensive cards?
Water Card (Deck of Dungeon)
Turns floor tiles around you into water, at high power turns a lot of tiles and some into deep water. Just like Fedhas' rain invocation, instantly drowns non-flying, non-aquatic, non-giant-sized creatures, Although you have to be careful with getting trapped and loot if you can't wade into deep water.
Swap Card (Deck of Escape)
Exchanges positions with a random monster, can be used in combos offensively:
* Levitation/Flight/Flight Card + Swap Card - while over lava or deep water
* Metamorphosis Card/Spider Form(Clinging)/Bat Form/Ice Form/Dragon Form + Swap Card - while over lava or deep water
* While in a Cold/Fire/Mephitic/Miasma/Poison Cloud + Swap Card
* Tomb Card + Vitrification Card + Swap Card - traps a monster in a glass cage for eternity, unless it has teleport or digging(someone confirm?)
Damnation Card (Deck of Escape)
Banishes random creatures within your vicinity into the Abyss, at high power it banishes a larger number of monsters. Ala Lugonu's banish but multi-target, randomized and risky since it can also banish the player. Great use if you are surrounded and without any means to escape: it either clears the room, or lets you escape into the Abyss(for better or for worse)
