3. There is a respawn point at continent borders, for a total of 19. They are exactly at the vortex that allows you to cross from one continent to another.
I feel it important to point out that a few of the portals listed are not on the edge of a region and thus may not seem like they are a border but they actually are. The portals to/from Prime Roots may appear in the middle of the Jungle or Desert, but they are still the border between PR and wherever.
"Border" doesn't always mean "edge".
