No XP for summoned creatures, right?

[borc killer]

IMC I give XP for summoned creatures if the party doesn't actually fight the summoner (IE, badguy laughs, summons some stuff to fight them, says "Kill them my minions!" and teleports out in bad cinema style.) Usually done in cases when fighting the summoner would kill them anyway.

If the summoner sticks around, no XP.

That is what I do as well.

If the summoned creature is created as a result of a summon monster spell or summon nature's ally spell, I don't give XP for it.

However, if the creature is gated in, called, or similarly brought to the battle by means of not a short-term spell like those I mentioned above but a much more long-term summon where the summoned creature can act independant of the summoner in many ways, I give XP.

The first set of spells feel more like an extension of the spellcaster, and the second set seem more like independant actors.
