Welp, I just spent the past 5 or 6 hours tonight getting this ready and all appear well. The Anti-Magic Field is a new floor event that can rarely happen from floor 5 onward. It can also stack with many other floor events which should be interesting.
What it does is completely negate both you and the enemy's magic spells from working. The good news is that the enemy is too stupid to realize what's happening and will try to continue to cast spells, being a big advantage to you. Of course if you're a wizard yourself or are using weapons that have magical spells you better be extra cautious on these floors.
Spells affected by Anti-Magic:
FLAMES
ICE
ZAP
HEAL
RUST
MORPH
BLIND
The HEALTH and STAMINA options a held Totem gives you are special and will still work while in an Anti-Magic Field.
In addition, there is a new item you can get from high tier golden and any shadow chest that will instantly create an Anti-Magic Field when used. Imagine how useful this'd be when you're preparing to go up against some champ or boss enemy loaded with strong spells?
I think that's enough for tonight, I gotta' go sleep. ːJAC_Clericː
