Henry V's Battle Helmet

Origin
Henry V (9 August 1386 – 31 August 1422) was King of England from 1413 until 1422 and was the second English monarch from the House of Lancaster. He first gained military experience fighting the Welsh in the northern territories, including Owain Glyndŵr. He next came in conflict with the government and his father, King Henry IV. Henry V ascended to the throne with his father’s death to face the French in the Hundred Years’ War, ending in a massive victory at Agincourt. Months of negotiation led to France declaring Henry heir, who married the daughter of King Charles VI.

Effects
When the wearer is physically injured, the helmet will emit a pink tinted energy shield to protect the user from further harm. It appears only moments before impact with objects, whether they are blunt or sharpened.
