What defenses kill own troops?

[PickleJar]

I just watched an interesting clan war attack in which one of our bases had a few valkyries in the clan castle, and when they came out to attack some golems (only golems, so they were not being attacked by enemy troops), the mortar went into action and did a lot of damage to them. Presumably the mortar was targeting the golems and the valkyries were taking splash damage. I'd been under the impression that one's own spells and defenses didn't damage ones own troops (we tested lightning and wall breakers, which I thought at one point damaged our own troops but in testing did not), so I was surprised.

My question is: what does, and does not, damage your own (clan castle) troops as they defend their own base? According to the attack I watched, mortars do. Do traps? Can they hurt each other?

you sure the valks weren't under a poison spell?

your defenses don't harm your cc troops or heroes at all

Your own troops do not receive damage from own defences. There was evidently wizards or something nearby. If convinced otherwise, upload a vid to YouTube and let everyone else judge.

When Golem splits (and also when resulting golemites die) they do damage to anything nearby. Quite a bit of damage, actually. Two max golems could kill the max valks with just their damage on death.

Tips to make youtube videos look less like ♥♥♥♥ appreciated. This is my first time trying to put a screen captured video (which looks crystal clear on my end before I upload it) on youtube.

EDIT: just read the post about golems exploding which I hadn't considered -- will look closely for that.
