Carrying Portal Scrolls is usually recommended unless a player is using the Portal skill gem. Players may also use Portal Scrolls to go in and out of town, to immediately refill flasks and heal to full while in the middle of combat. However, this strategy has limited value in a map since the number of portal trips is limited to six.Because Portal Scrolls are quite common, it is typical for players to use Portal Scrolls more slowly than the rate at which they drop.

Portal is a spell that performs the same function as a Portal Scroll, creating a portal to the current act’s town. Portal is a colourless gem and can be placed into any item socket.It is a normal spell so it is affected by support gems like Faster Casting Support, Cast on Death Support, Cast when Stunned Support, Spell Totem Support, etc.
Unlike most gems, Portal does not gain any experience and therefore cannot level up. It is possible to gain an additional level on a Portal gem by corrupting it with a Vaal Orb, and the gem can also have its level temporarily increased by items or Empower Support. However, increasing the gem level has no effect.
