Invisibility is a highly useful tool for both player characters and DMs.
Handled well, it can create surprises and unexpected encounters. However,
invisibility requires careful judgment on the part of the DM, lest situations occur that
could unbalance a scenario or campaign.
First, an invisible creature is invisible to everyone, including itself. This
is normally not a great difficulty; most creatures are aware of their own
bodies and don't need to see their feet to walk, etc. However, when attempting
detailed actions (for example, picking a lock or threading a needle), invisible
characters have serious problems, suffering a -3 (or -15%) penalty to their chance
of success. This does not apply to spellcasting.
Second, invisible characters are invisible to friend and foe. Unless care is
exercised, it is easy for a visible person to blunder into an invisible
companion. Imagine a fighter swinging his sword just as he realizes he doesn't know
where good old invisible Merin is standing! The problem is even worse with a group
of invisible charactersócharacters crash and tumble (invisibly) into one
another, all because nobody can see anybody. It would be like having a roomful of
people play pin-the-tail-on-the-donkey all at once!
