In Vikings War of Clans, the War Bloc allows you to mount an onslaught against an opposing Jarl’s town.
An onslaught is effectively a march on another player’s town, which allows members of your clan to join in. Your Hero will lead the attack with your own troops, plus troops donated from other clansmen.
For each level you upgrade your War Bloc, the number of supporting warriors donated from other clansmen increases. At level 21 you also receive a 10% attack bonus to all onslaughts.
All the troops in the onslaught will have the owner’s hero combat boosts applied to them. When you start the onslaught you can decide a time between 5 minutes and 8 hours, before your troops leave your own town. This allows other members of your clan time to join in on the attack.
The War Bloc needs Warrior’s drafts to upgrade as well as the standard resources. These can be found by attacking invaders or by purchasing them in the clan store for 300 loyalty each.
The table below has the build cost for each upgrade level from 1 to 21, the build time (before boosts), buildings required and the influence rewarded.
