Part of the Zaoan Set. It is better than the Demon Helmet, since the Demon Helmet has one armor value more, which blocks 0.7 damage on average, while the Zaoan Helmet has 5% protection against Physical Damage, which blocks at least 1 damage.
If a creature hits an average of 100 damage every hit, Demon Helmet will reduce the damage with a minimum of 4.8 and a maximum of 8.5 while Zaoan Helmet will reduce it with a minimum of 4.3 and maximum of 7.6 with an additional of 5%.
In the end, Zaoan Helmet will reduce the damage by 9min and 12max compared to Demon helmet with 5 min and 9 max.
Dwarven Helmet only reduces the damage by 2.9 min and 5.7 max with an additional amount of 2% which goes towards reducing 4.8 min and 7.6 max. Keep in mind that "100 damage" was used for the calculation. The price of the Zaoan Helmet has decreased since the Elite Draken Helmet was implemented because it was first used by many Paladins.
