The invisibility spell makes the affected person invisible to the natural eye.
Only those who have been magically affected to see invisible can see those who 
have concealed themselves by the invisibility spell.  A person affected by the 
invisibility spell would become seen again if he is engaged in combat.  

The mass invis spell makes all the people or creatures in the caster's
group invisible, including the caster.  It has a similar effect as casting the 
invisibility spell to each and everyone in the group, thus, whoever engages in 
combat while invisible will cease to be invisible.
