Only two.

The meeting went on for a couple of hours during which Sam and Mimir decided their next course of action and ironed their objective in the next battle.

Now that they had several hundred Nephilim on their side, reaching the portal gate was no longer their top priority. However Sam saw it fit to leave a detached force that would focus on that part. Getting reinforcements from the forty sixth base would definitely tilt the scales in their favor.

The second objective would be freeing the captured Nephilim. This was an obvious step, one that was absolutely required to get Mimir's support. Eliminating them wasn't an option so it was going to be a really tough nut to crack, especially when considering the final point.

The third objective, and the most important in Sam's opinion, is stealing the Key the Olympians were trying to obtain. This was what made things a bit complicated.
