Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

I tried using Contingent Summoning on my cleric with the Rune Domain that gives Lesser Planar Binding Spell. Instead, the ability casts Summon Creature V though I don't even have it memorised, only the aforementioned Lesser Planar Binding.

If it's a bug, my best guess is Contingent Summoning doesn't take into account domain spells.

Edit: The ability's in-game description is simply misleading. It states that it works through memorised spells while it actually works through known ones. The wiki seems to have a more accurate description of the ability.

Contingent Summoning always chooses the highest summon in the spellbook.

For a cleric, I’m going to assume it takes the summons for the highest spell level your PC can currently cast.

Ah, I see, thanks. I thought it was tied to the highest summon spell memorised like many other spell-like abilities. Still, it's weird to have a summon creature spell prioritised over a Binding/Ally one. Kind of makes the ability useless if you're not into summoning creatures, at least, on clerics who can't avoid getting that line of spells. Not mentioning the power gap between them and planar summons. Well, I guess it's a coding issue or something. Some old topic on this states it's intended.

Well, I see where all the confusion is coming from for me. The in-game description of the ability states that it's all about memorised spells. While the wiki says it's actually about known spells.

Yeah, clerics would need to use Contingent for a Summoning, and memorize a Planar Ally. Still not bad!
