My group has only recently started running into dispel magic in Pathfinder and I'm not sure entirely about the effects on certain spells. I understand how things work when dispelling single target effects even with multiple effects on a target but what about a multi target spell such as haste or communal resist energy. What about multiple creatures summoned with one summon spell?
Dispel magic says "You make one dispel check (1d20 + your caster level) and compare that to the spell with highest caster level (DC = 11 + the spell’s caster level). If successful, that spell ends."
So is haste dispelled from only the target or does the "spell" end along with all of its targets. What if I specifically target the spell haste itself instead of a creature. Would it then be considered "a spell affecting an area" like wall of fire? If I target a summon spell do all the summoned creatures disappear or do I have to target a single creature?
Especially with the reduced effects of the spell it seems like I should be able to take down a whole spell and not just one target worth of its effects. I know in 3.5 I always used the rule that it only affects one target but back then there was an AoE effect which could be used to target multiple effects from one spell.
