Which monster does the summon focus on? Long way around, avoiding traps, or get stuck behind a player?
Focus: Living Bones 6
Target Hex: The hex next to Living Bones 6 and Living Corpse 6.
Path: Path 3
Move To: First hex of Path 3.



1. Determine the focus.

I'm assuming the summon doesn't fly, and that the summon has a melee attack.


The minimum amount of movement required to attack Living Bones 6 (without setting off the trap) is 5.
The minimum amount of movement required to attack Living Bones 9 is 5.
Even if given infinite movement, the summon can't attack Living Corpse 3.
The minimum amount of movement required to attack Living Corpse 6 (without setting off the trap) is 5.


This rules out Living Corpse 3, and leaves us with a three-way tie. Proximity is the first tie breaker.


Living Bones 6 is 3 hexes away.
Living Bones 9 is 3 hexes away.
Living Corpse 6 is 4 hexes away.


This rules out Living Corpse 6, and leaves us with a two-way tie. Turn order is the second tie breaker. Living Bones 6 acts before Living Bones 9, so the summon will focus on Living Bones 6.

2. Determine the target hex.

I'm assuming the summon doesn't fly, that the summon has a melee attack, and that the attack targets a single opponent.

There is only one hexes from which the summon can attack Living Bones 6, so the summon will move towards that hex.

3. Determine the path taken.

Giving an infinite movement, Path 3 is the only shortest that doesn't set off the trap.

4. Move as much as possible along the path.

The summon will end its movement in the first hex of Path 3.

  Both Living Bones 6 and 9 are 2 hexes away, so by default I would assume that it tries to focus on Living Bones 6


This is not correct. They are 3 hexes away, and proximity is not the primary criteria for choosing a focus. The primary criteria for choosing a focus is the minimum amount of movement needed to get into range to attack the candidate.


  If it tries to take Path 1, it gets stuck behind the player and cannot attack.


Even given an infinite movement, that path won't ever be fruitful. That rules out that path.


  Path 4 is 4 hexes, but it goes through an obstacle, so for determining focus I believe we're supposed to treat obstacles as barriers unless there is absolutely no other possible path. (Is that right?)


Correct.


  Path 3 is 5 hexes to get to Bones 6. Path 2 is 5 hexes to get to Bones 9. Since both of those paths are 5 hexes long, I assume the initiative order is the tie-breaker and so it would focus on Bones 6.


You first need to rule out Living Corpse 6 (also 5 hexes). See above.


  The summon has 2 movement.


This isn't relevant any point in the decision process. Always assume an infinite movement of the current type (flying or not).


  On a subsequent turn, assuming it's still focusing on Bones 6, would it continue to be stuck


There's no point in guessing what it will try to do next turn as that's also irrelevant.


  The trap in Path 4 does enough damage to the kill the summon.


Not relevant.

If the only path to its focus would bring it to the trap (which isn't the case here), it will go through the trap even if it kills it.


  Or, as a wildcard option, would the summon choose to focus on Bones 6 but take Path 5 because it's the only path that it could ACTUALLY fully complete?


There's no point in guessing what it will try to do next turn as that's also irrelevant.
