ClanOps · Updated

Overview
The Portal Master opens portals on the World Map, helping your army reach distant locations without marching the whole distance from your City.
You need a Portal item or a Portal to Another Kingdom item in your Items section to open the corresponding portal.
Types of portals
| Portal item | Where it takes your army | Availability |
|---|---|---|
| Portal | Within your own Kingdom | Use a Portal item |
| Portal to Another Kingdom | Another Kingdom | During Clash of Kingdoms |
Portals and attacks
An enemy can attack your open portal even while your City has a Shield of Peace. Your Walls do not participate in that battle.
A successful enemy attack causes all your open portals to disappear. A shield on your City does not protect your portals.
Duration and portal limits
Upgrade the Portal Master to extend portal duration and increase the number you can have open. Researching Portal duration and Maximum portals technologies also improves these limits.
The building allows a second portal at level 20, a third at level 30 and a fourth at level 40, before any additional research effects.
Level benefits
Building benefits by level. Research can further affect portal duration and capacity.
