You could, but at that point it's become something very different to triggering the attack - the attack isn't triggered (it's performed by it's user by playing the animation, which is just attacking), and it isn't you doing or triggering it - it's a mirage or similar totem-style object, which has all kinds of mechanical consequences. We could do that, but it would be fundamentally different enough from triggering that we couldn't call it that.

Conveniently, the only part a triggered bow skill needs is to fire the arrow, which is the simple to fake part of the animation that matches how most skills work. The other stuff in those animations is mostly to do with turning visiblity on and off for the arrow the character has ready in their hand (hide it when you fire, show it again when you reach to the quiver so it looks like you grabbed a new arrow) and making the bowstring animate - both of which a triggered bow skill doesn't really want because they would conflict with any non-triggered bow skill you were doing at the same time.

Melee skills (especially strikes) tend to have more mechanical info in the animation that makes generic triggering of them much harder.

The problem there is a skill can't have multiple triggers. Since counterattack skills already have a trigger built-in, adding another trigger would disable them.

I am very sorry for your loss. Stay strong!

That isn't how ancestral call works. The ancestor is entirely a client-side visual effect with no impact on mechanics - the attack is driven by your character's animation.

what would it look like?

Ngamahu's Flame.

No, really. Probably not exactlly like it, but a lot like it.

So far as I'm aware, this wasn't intentionally created to match with the other two you mentioned, but it ticks a lot of boxes that I think fit.

Fire is the element associated with strength, so it would make sense for the fire one to trigger attacks rather than spells, as a point of difference - it's always more interesting to have a cycle where one sticks out a bit than where everything is clean mirrors of each other (see added fire damage support or hatred as exceptions to their cycles, for example).

But because attacks are very animation-driven and triggered skills can't play animations on the character, we can't just trigger arbitrary socketed attacks - they just won't work (and/or will horribly crash). So it supplies it's own attack that's very generic - scaling on attack, physical, fire, projectile, ...

If this is correct, it is a bug, and I will look into it. Skill Popups are explicitly not meant to display stats from passives, gear or otherwise on the character - only stats from the skill itself. This is because if they displayed all the stats from those other sources, all your skill popups would (a) contain a lot of duplicated information and (b) be unreadable messes with hundreds of stats mixed in together and in some extreme cases not fit correctly on the screen, making it impossible or unfeasible to actually find the relevant stats in display.

This has nothing to do with this case relating to minions, just that the skill popup is fundamentally not where passive stats belong, for any skills.
