Added the new spell to compare. Not taking duration into account of course since it's handled differently now. But as you caqn see both cast range and the area which the targets may spread out has changed a lot.
The D&D Next Variant:
Choose one creature within 100 feet of you. That creature and any creatures you choose within 20 feet of it become invisible. The creatures remain invisible until your concentration is broken, but for no longer than 10 minutes.
If any creature affected by this spell attacks or casts a spell that affects a creature other than itself, the effect immediately ends for all creatures affected by the spell. Furthermore, the spell ends for any affected creature that starts its turn more than 30 feet from any other creature affected by this spell.
The 3.5 Variant:
|Components:||V, S, M|
|Casting time:||1 standard action|
|Range:||Long (400 ft. + 40 ft./level)|
|Targets:||Any number of creatures, no two of which can be more than 180 ft. apart|
|Duration:||1 min./level (D)|
|Saving Throw:||Will negates (harmless) or Will negates (harmless, object)|
|Spell Resistance:||Yes (harmless) or Yes (harmless, object)|
The creature or object touched becomes invisible, vanishing from sight, even from darkvision. If the recipient is a creature carrying gear, that vanishes, too. If you cast the spell on someone else, neither you nor your allies can see the subject, unless you can normally see invisible things or you employ magic to do so.
The effect is mobile with the group and is broken when anyone in the group attacks. Individuals in the group cannot see each other. The spell is broken for any individual who moves more than 180 feet from the nearest member of the group.
