Marvel Avengers Alliance Shields and Force Fields Guide by Cidolfas

Only shields which actually absorb damage are included. Buffs such as “Mirror Image” has the same animation like a shield, but since it does not actually absorb damage, it is not get included here.

How multiple-shield stacking works:
Shields which are in the same category replace each other. Shields from different categories can be stacked.

?Reflective Shield?????2

When taking damage, the shields will work on first-come-first-serve basis. That means, the shields which are applied first will take damage first, regardless of the categories.
* Update for Base Health: Base Health is now the health of a character including PVP bonus, but without ISO bonus.
1 Assuming IW’s “Fourth Field” doesn’t overwrite Cable’s “Cone of Silence.”
2 “Reflective Shield” is mentioned in ToyMaker’s post:….k-of-8-31-2012, but I have never encountered this shield yet. Inputs will be much appreciated!
& Probably due to a bug, the extra turn will still be granted upon the destruction of “Magnetic Field” even if the character already has “Exhaustion” status.

Definition of a shield:
Shield or Force Field is a protective wall buff which – if the incoming damage is less than the shield’s strength, the attack does not ignore defense and penetrate shield, and not a psychic attack – have 100% chance to activate and could absorb the entire incoming damage in place of the character being protected[1][2]. Furthermore, the shield will show a certain amount of hit points after taking the attack, unless the shield is completely destroyed or have unlimited strength[3].

[1] The easiest way to test whether a shield or the character taking the damage is to see if you still have the “Perfect Strategy” bonus at the end of battle. If you still retain the “Perfect Strategy” bonus despite taking the damage, that means, it was the shield/force field (or any kind of protective wall) which actually took the damage, not the character.

[2] Thing’s “Stonewall” is considered as a shield since it passed the “Perfect Strategy” test. You still retain the bonus even after Thing’s “Stonewall” got hit. It’s like Thing set up some kind of a wall in front of him to take damage instead of Thing itself. This, I would consider a ‘shield’ in itself. On the other hand, Colossus’ “Steel Fortress/Curtain” and Emma’s “Diamond Body” do not satisfy part of the criterion since you will lost the “Perfect Strategy” bonus if those characters are hit while the protections are still active. This implies that the characters themselves took the (reduced) damage, and thus, their abilities are not included in this thread.

[3] While Vector’s “Kinetic Shield”, Invisible Woman’s “Force Cage” and Baron Mordo’s “Crimson Band of Cyttorak” protect the character and have unlimited strength, only Vector’s “Kinetic Shield” is considered as a shield because it’s a buff-type effect. IW’s ‘Force Cage” and Baron Mordo’s “Crimson Band of Cyttorak” are not considered as a shield because they are debuff-type. With the same argument, Grey Gargoyle’s “Complete Petrification” is also removed from the list since it’s a debuff-type effect.

[4] Some shields may only block or pass certain type of attacks or characters with certain attributes, for example Magneto’s and Fixer’s shields.

[5] Due to constant (undocumented) updates of the game, the shield strength may be a little bit different from what we have calculated initially. For example, Iron Man’s “Deflector Shield” strength is now 40% of his Base Health (previously 55.5%). I have not checked every shields’ strength (and will not check every time we have an update), so the numbers listed may not be perfectly accurate. Apologize for the inconvenience. On the other hand, if you are a detail-crazy person (and more detail-crazy than me) and would like to keep this guide accurate, feel free to let me know of any inaccuracies and I will give you credit. Thanks!
