目盲且耳聋的生物去找人就太跑题了，和对方隐不隐形一点没关系了。
关系还是很大的。两者都是通过unseen and unheard导致必须要猜格子，只不过隐形（unseen）加躲藏（unheard）是从源头解决问题，目盲加耳聋是在末端解决问题。通常来说前者会好一点，可以一次迫使多个敌人猜格子。但是遇上能够看破隐形的敌人后者才能奏效
躲藏这个词本身看着似乎跟声音关系不大，但声音其实是写在躲藏相关规则里的。躲藏不只是保持安静，但保持安静是必要条件
HidingThe GM decides when circumstances are appropriate for hiding. When you try to hide, make a Dexterity (Stealth) check. Until you are discovered or you stop hiding, that check's total is contested by the Wisdom (Perception) check of any creature that actively searches for signs of your presence.
You can't hide from a creature that can see you clearly,
and you give away your position if you make noise, such as shouting a warning or knocking over a vase.
An invisible creature can always try to hide. Signs of its passage might still be noticed,
and it does have to stay quiet.
