Arda

I would make a suit of rohan armor out of mithril

I like Gil-Galad's armor the best. This was copid from tolkien wiki.

The Armor of Gil-Galad
Gil-galad's armor was similar in composition to that of all the elves of the Second Age: a cuirass and fault of interlocking lames of steel plate over a hauberk of fine mail, together with pauldrons and braces. However, befitting his status as High-king, his armor was blued and etched with vine like tracery, and the plates were embossed with tengwar symbols and included leather pants, which gave greater protection. At the throat he wore a steel collar that bore his heraldic insignia, twelve stars on a midnight-blue field. The color blue may have reflected an association with the sea; in any case, it was certainly a dye that was rare on Middle-earth, and it would have required a great deal of time and knowledge to locate enough flora or fauna with which to make it. His cloak was of a deep blue and his armor was golden, and instead of a helmet he wore a golden crown, fashioned for him by the smiths of Eregion, possibly by Celebrimbor himself, who made the Rings of Power.

The Shield of Gil-galad.
The shield of the High-king was the same shape as the regular elven shield, but like his armor it was more richly adorned: it was enameled in blue on and around the boss and decorated in gold with the twelve stars of his house. Because Aeglos (his spear) was wielded two-handed, it is likely that the shield was carried only to the field of battle rather onto it, to be left with one of Gil-galad's attendants.

Something as trivial as that probably wouldn't cause his death.
