World raids are special raids which do not have a health bar and are only "defeated" when the timer runs out.
They do not have essences, but are rather summoned by one of the game's developers whereupon a link appears on the ingame home page.
World raids last for several days (as opposed to Event Raids that last 24 hours).
The cap on the number of players which can join a world raid is set arbitrarily high (90,000) so that all players on a given server may join.
The goal of world raids for each player is to deal enough damage to qualify for a loot tier (as appears on the loot tables).
- There are currently 18 different World Raids in the mobile version of DotD.
