Shield of Chaos

Aegis, the Shield of Chaos is an Infernal Arm that can be unlocked for 3 Chthonic Keys.

Fighting style
The main attack is a single swing that hits in an arc and knocks enemies back. Holding the attack button will block damage from the front, and releasing will perform a shield bash forwards, dealing damage to enemies hit. The special throws the shield, which bounces between enemies and objects before returning.

It's worth noting that the shield is capable of blocking nearly anything, including attacks from bosses, except for traps and AoE attacks.

Aspects
The Shield of Chaos has 4 Aspects: Zagreus, Chaos, Zeus, and Beowulf. Like all other weapons, each Aspect has 5 levels that can be unlocked by spending Titan Blood. The higher the level of the Aspect, the more effective its improvement is. Reaching the highest level in all Aspects requires 51 Titan Blood. An Aspect will not only change the appearance of the Shield of Chaos, but will also improve its attacks. The Aspect of Beowulf has a unique move-set which changes the fighting style of the Shield of Chaos. * Blitz Disc will move through foes until stopping in place for 10 seconds or until Special is pressed again, at which point it travels back to Zagreus. Deals damage every, even when travelling back. You can still Attack before the shield is recalled.

Revealing the Aspect of Beowulf
Reveal the Aspect of Beowulf by meeting the following requirements: "You come to my domain bearing an all-seeing artifact that sprang from me after the dawn of time. It is considered a defensive instrument, I do believe. Though, I suspect you have discovered, or soon shall discover, it is nothing of the sort."
 * Reveal the Aspect of Guan Yu (does not need to be unlocked with Titan Blood)
 * Have a total of 5 or more invested into Shield aspects
 * If you have not previously received the following dialogue from Chaos, talk to them with the Shield equipped until you do:

"I bear a message for you, Son of Hades. One recorded in an age when certain concepts it describes did not yet all exists. Remember this: I see you stand your ground against the serpent's flame. A waking-phrase, to which you and the all-seeing artifact of my creation may respond."
 * Talk to Chaos (with any weapon equipped) until they give you the waking-phrase ("I see you stand your ground against the serpent's flame")


 * Equip the Shield at the House and then interact with its placeholder to reveal the Aspect of Beowulf

Additional notes

 * The Shield of Chaos is based on the Aegis from Greek mythology.
 * Both Charged Shot and Power Shot ignore shields wielded by Greatshields and Theseus. Shield throws can also circumvent shields if homing in from the back.
 * The bonus shields from Chaos aspect are not affected by Explosive Return. Catching all the shields will only deal area damage once.
 * The bonus shields from Chaos aspect are not affected by Dread Flight. Only the uncharged shield throw bounces 6 times. If you use Bull Rush to activate the Chaos aspect bonus, all shields thrown will only bounce once.
 * The bonus shields from Chaos aspect are not affected by Dashing Flight. If you use Bull Rush to activate the Chaos aspect bonus, then activate Dashing Flight, only the center shield will become faster and deal extra damage.
 * When using the Aspect of Chaos, Chaos will occasionally speak throughout the run.
 * When using the Aspect of Beowulf, the boons for your cast will have different names. Example: Flood Shot -> Flood Flare
 * When using the aspect of Zeus, any boon that upgrades your Special (for example lightning strike), will apply the effect for each tick of damage that the special deals, same is true for the Ares doom effect and Dionysus hangover.
