|套装奖励||Double tap ▼ 下/▲ 上 to call an ancient storm to the cursor location|
With the full set equipped, a golden spiky rune-like object, known as the Forbidden Sign, floats behind the player in a very similar fashion to the 星尘守卫 from the 星尘盔甲 set. Double tapping ▼ 下 or ▲ 上 (depending on the Activate Set Bonuses setting) will send a beam of dust particles that summon a Sand tornado at the nearest block surface beneath the cursor position at the cost of 20 mana. The beam itself does not deal any damage, but the tornado deals continuous damage to any enemy that comes in direct contact with it. The Sign also casts a faint yellow light around the player, similar to the 挖矿头盔.
The storm summoned by the Forbidden Sign rapidly hits for 20 base damage, and is affected by both increases to magic and minion damage (effectively making the Forbidden Mask add +30% damage). Items that increase all damage types (like 天界壳 or 复仇者徽章) will effectively contribute their value twice. The storm's critical strike chance is based entirely on the player's magic critical strike chance.
The dust particles can not pass through solid objects, which means that if there is a solid object between your character and the cursor, the beam will hit the solid object, stop there, and the Sand tornado will not be summoned. Only one sand tornado can be summoned at a time, and when a new tornado is summoned, the old one disappears after roughly 1 second. A space of at least 3x12 blocks is required for the tornado to be summoned. If no enemies come in contact with the tornado, it disappears after 15 seconds.
Forbidden armor is the Desert counterpart to the Snow biome's 寒霜盔甲, buffing magic and summon weapons instead of melee and ranged.
